VSATPlus 3 > Overview > Functional Description

Functional DescriptionThis topic provides background information about and describes the operation of the VSATPlus 3 network.

TDMA Overview The VSATPlus 3 system makes maximum use of satellite bandwidth by combining Time-Division Multiple Access (TDMA) and Frequency Hopping (FHOP) techniques. Each station transmits short, high-speed bursts, one at a time for a given frequency. To do this, each earth station temporarily buffers its user information, and then it periodically transmits that information to the satellite in a short burst. Each burst is timed, or synchronized, so the bursts received on a given frequency by the satellite are closely spaced in time but never overlap. This approach assures that the satellite amplifies and retransmits bursts to all nodes.

As a result, each VSATPlus 3 Terminal can receive information from all other earth stations with no additional hardware. This factor is significant in making TDMA lower in cost and more flexible than other multiple-access methods.

The terms Node and Station have the following specific definitions:� Node � Addressable point on a network that is associated with one TDMA

terminal� Station � Geographical location of nodes including the Radio Frequency

(RF) equipment

Although a VSATPlus 3 network is hubless, it does contain primary reference and non-reference nodes:� The VSATPlus 3 Terminal that is the primary reference node provides the

primary timing reference signal that defines the start of the signaling channels, the start of the first frame, and the start of the superframe.

� The VSATPlus 3 network contains a primary and a secondary reference node that may be geographically distant from each other. The secondary reference node transmits the reference signal when the primary node stops transmitting the signal.

� The other VSATPlus 3 Terminals are the non-reference nodes.� Any node can become a reference node. The terminal hardware is the

same at all nodes.

Burst, Frame, and Superframe Architecture

This topic describes the architecture of bursts, frames, and superframes in the VSATPlus 3 system.

Superframe, Frame, and Burst Structure

Burst StructureEach burst includes the following:

Guard � Period of time during which no node transmits� Assures that no bursts overlap due to the imperfect timing of transmit

bursts from one node to the next� Compensates for differences in clock frequency between nodes and the

doppler effect (satellite motion)

Preamble � Sequence of ones and zeroes providing defined transitions for the demodulator� Defines where information bits are located within the burst� Used to detect the start of a burst and estimate carrier phase, carrier

level, and symbol timing

Payload � Sequence of data that begins immediately after the preamble and contains an integral number of turbo blocks

Tail � Segment of bursts that incrementally reduces the transmit power

Frame StructureBursts are arranged in frames. Each terminal is allotted bursts in the frame to transmit traffic. A frame is made up of three types of bursts:� Network Broadcast Channel (NBC) burst � Transmitted by the

primary reference node to manage network configuration, status, and bandwidth allocation

� Common Signaling Channel (CSC) burst � Used by each node to transmit to the primary reference node, configure and synchronize to the network, respond to queries, provide status, and request bandwidth allocation. Each node has one or more CSC slots in the superframe.

� Customer information bursts � Includes information from a single node. Information is normally contained within IP packets that are routed to the Ethernet port of the destination terminal.

Superframe Structure

Characteristics of a superframe include:� The number of frames present is sufficient to include a CSC burst from

each node.� The number of frames in the superframe and the number of CSCs per

frame determine the maximum number of nodes that can be supported in the network.

Each node tracks the superframe count that is transmitted by the primary reference node. This count is used to make sure that all nodes add or delete bursts at the same frame boundary.

Burst Types and Characteristics

Type Characteristics Uses

Customer Information Bursts

Can include any type of IP traffic:� Voice over IP (VoIP), World Wide Web

(WWW) sites, transaction data, data transfers

� Forward Error Correction (FEC) may be applied

� Quantity and size depend on usage and the network configuration.

These bursts carry the data for the customers in the payload.

CSC Bursts Common Signaling Channel

Built-in signaling channel:� One or more CSC bursts for each node

in each superframe� FEC is always applied.

� Carries signaling information for the network

� Return channel to the primary reference node for signaling

� Network acquisition and synchronization

NBC Burst Network Broadcast Channel

The main communication channel from the primary reference to the network:� Contains identification information

about the primary reference node� One NBC burst for each frame� FEC is always applied.

� Carries signaling information for the network

� Downloads from the primary reference to update the parameter lists. The parameter values are the same on all nodes.

� Command network reconfiguration � For example, to redefine which node is the primary reference node and which is the secondary reference node

� Status inquiry � The response to this inquiry is contained in the CSC bursts from each node.

� Bandwidth allocation



Typical Superframe Structure

TDMA Acquisition

TDMA acquisition is the process that a node uses to join the network.

Acquisition has two phases:� Receive Acquisition � The node finds the reference signal that indicates

the start of a superframe and frame. During receive acquisition, the terminal sweeps through time, frequency, and amplitude as it searches for the reference signal.

� Transmit Acquisition � When the terminal finds the reference signal, it starts the transmit acquisition process. The terminal determines the time to transmit to the satellite based on the distance to the satellite. To determine transmission timing, the terminal uses the configured locations of the terminal and the satellite, along with the distance estimate provided by the primary reference.

The center of a TDMA network is the satellite. Bursts must arrive at the satellite within two symbols from their expected arrival time. Otherwise, the integrity of the network is at risk if TDMA channels start to overlap.

All terminals, except for the primary reference node, must complete receive acquisition and then transmit acquisition. The primary reference does not need to complete transmit acquisition because it is the first node to start in a network. It can start transmitting at an arbitrary time, and needs only to perform receive acquisition on its own signal.

Primary Reference Node AcquisitionThe Primary Reference Node provides network timing in the VSATPlus 3 network. The Primary Reference Node is the first node that is acquired in the network. Any node in the network can become the primary reference node, but only one node is the primary reference node at any time.

During acquisition and synchronization:a The Primary Reference Node transmits and receives back its own

reference (REF) bursts.

b The Primary Reference Node measures the round-trip satellite delay between the transmit and receipt of reference bursts. The round-trip time is estimated from the geographic coordinates that are configured at the terminal, and from the coordinates of the satellite. The difference between the estimated and the measured round-trip times indicates the distance the satellite has moved in the center of its orbit. The primary reference node broadcasts the difference to the other nodes in the network so that they can complete transmit acquisition more quickly.

Primary Reference Node Acquisition

Non-Reference Node Receive AcquisitionThe following events occur during receive frame acquisition:a The non-reference node detects the reference signal in the superframe

received from the Primary Reference Node.

b The non-reference node synchronizes the receive frame timing with the primary reference burst.

c The non-reference node synchronizes its superframe count with the superframe number received from the Primary Reference Node.

Transmit AcquisitionDuring transmit acquisition, the VSATPlus 3 Terminal at a non-reference node:a Estimates the round-trip delay form the geographic location and adjusts

the round-trip delay with information from the Primary Reference Node. Geographic location includes the latitude, longitude, and elevation of the node as well as the longitude of the satellite.

b Transmits a burst during a CSC slot that is assigned to this terminal number.

c Adjusts the timing of the transmit burst to compensate for differences between the estimated and the measured round-trip delay.

Transmit Acquisition

Symbol Clock SynchronizationAfter acquisition, the VSATPlus 3 Terminal must monitor its timing in relationship to the network, particularly to the Primary Reference Node. Correction for any timing shifts caused by differences in local oscillators and satellite motion (Doppler shift) is done automatically.

Primary and Secondary References

In a VSATPlus 3 network, the primary node provides the reference signal that indicates the start of the superframe. You can configure one other node to be the secondary reference node. The secondary reference node monitors the primary reference signal. If the primary reference signal stops, then the secondary reference node starts to transmit the reference signal in the second reference slot. The secondary reference node becomes the primary reference node and takes control of the NBC channels.

After the secondary becomes the primary reference node, you can assign a new secondary reference node in the network.

First and Second Reference Slots

Note: � The primary reference node provides timing for all nodes in the network.� A secondary reference node is the backup to the primary reference node.

The reference switchover occurs automatically. No manual intervention is needed.

� No extra equipment is needed for a node to become the primary or secondary reference node.

Bandwidth Pool As shown in the figure, Superframe, Frame, and Burst Structure on page 17, the timeslots from Carrier 0 to Carrier n are aligned over one another. This bandwidth pool is managed by the Bandwidth on Demand (BoD) server that is at the primary reference node. When you add a new carrier to the VSATPlus 3 network, it is automatically added to the bandwidth pool, and the BoD server manages the new carrier along with the previously configured carriers.

For detailed information about the rules to follow when you allocate bandwidth, see Configuring IP Links on page 48.


VSATPlus 3 > Overview > Configuration Overview

Configuration OverviewTo configure a VSATPlus 3 network:� First, you install and configure the VSATPlus 3 Terminal that will be the

primary reference node. This node provides the primary timing reference signal that defines the start of the signaling channels, the start of the first frame, and the start of the superframe.

� Then, you install and configure the other VSATPlus 3 Terminals that will be the non-reference nodes. Once the network is operating, any node in the network can become the primary reference node.

Primary Reference Node

On the primary reference node, you configure the parameters common to all nodes.

The system automatically activates and downloads parameter lists to all nodes in the network. Nodes that are not operating during a download of new parameters automatically receive the parameter lists when they join the network. These parameter lists are distributed to each terminal by way of the signaling channels � the NBC and CSC.

You can configure IP routes, IP links, and carriers when you configure the primary reference node. Alternatively, you can configure these parameters after you install and configure remote nodes.� Configuring the Primary Reference Terminal on page 36� Configuring the Global Network on page 42

Non-Reference Nodes

When you configure a terminal at a non-reference node, first you configure the node locally with the minimum number of parameters it needs to join the network. When the terminal joins the network, it receives the global parameters that are common to all nodes. These include the IP routes, IP links, and carriers that are configured on the primary reference node.� Configuring a Non-Reference Terminal on page 54

QoS Configuration

VSATPlus 3 Terminals are pre-configured with a default set of QoS rules, so you may not need need to configure QoS in order to make the VSATPlus 3 network operational. If the default QoS rules are not suitable, you can edit the rules after the network is operating.� Configuring QoS Rules on page 59

VSATPlus 3 > Installation and Configuration > Configuring the Primary Reference Terminal

Configuring the Primary Reference TerminalThis topic describes how to connect to the web-based user interface and configure the VSATPlus 3 Terminal that serves as the primary reference node in a network.

The primary reference node is the first node that starts in a VSATPlus 3 network. It provides the primary timing reference signal that defines the start of the signaling channels, and the start of the satellite frame and superframe.

On the primary reference node, you configure the parameters common to all nodes. The system automatically activates and downloads the global parameter lists to all nodes in the network. Nodes that are not operating will download the lists when they join the network. These parameter lists are distributed to each terminal over the signaling channel � the NBC and CSC. After the lists are distributed, and the configuration information from the primary reference is replicated throughout the network, any other terminal can become the primary reference node if needed.

The web-based user interface is identical on all nodes in the network. You can edit and save global parameters for the network � IP Routes, IP Links, and Carriers � only on the primary node. However, you can display these parameters from a non-reference terminal.

Note: � For background information about the configuration of a VSATPlus 3

network and a summary of which parameters you configure at the primary reference and non-reference nodes, see Configuration Overview on page 24.

Before you start: � Install the terminal � Installing a VSATPlus 3 Terminal on page 32.� Connect to the user interface for the terminal that will be the primary

reference node � Connecting to the User Interface on page 35.

Configuring the Initial Network Parameters

1 Select Configure > Network.

CAUTION!Risk of Loss of ConnectivityIf you change network parameters when the network is operating, you can break connectivity between nodes in the network.

2 The following parameters prepare the initial configuration. These parameters must be the same on every node in the network. Configure the following on the primary reference node:

Network SizeEnter the number of terminals in the network. The system uses this parameter to define the number of CSCs that are needed for signaling.� The range of values is from 1 to 1000.� The maximum number of terminals is limited also by the number of

signaling channels. Each terminal requires at least one CSC channel, so the number of terminals cannot be greater than the superframe size multiplied by the number of CSC bursts for each frame.

Symbol RateEnter the number of symbols that occur each second. Each symbol carries 2 bits for QPSK, or 3 bits for 8PSK.� The range of values is from 0.128 to 5.0 MegaSymbols/second.

Frame TimeDefines the duration of one TDMA frame in the network:� Select 20, 30, or 40 ms frames.



Frames per SuperframeEnter the number of frames for each superframe in the network. A superframe is a group of frames � Superframe Structure on page 19.� The range of values is from 10 to 60 frames/superframe.� Typically, select 30 or 60 frames/superframe.

Secondary Ref TerminalNote: � You can configure the secondary reference node only from the primary

reference node. It becomes effective only when the primary reference node is installed and configured.

Defines the node that operates as the secondary reference node in the network.� The secondary reference transmits the reference signal if the primary

node stops transmitting the signal.� The range of values is from 1 to the maximum number of nodes that

are in the network.

CAUTION!Risk of Network OutageDo not define the secondary reference node to be on the same terminal as the primary reference node. Also, make sure that the secondary reference node is geographically distant from the primary reference node. If the two reference nodes are close together, interference (for example, from a solar outage) can affect both terminals at the same time and bring down the network. In this case, the network loses the reference signal.

TPC parametersTurbo Product Code (TPC) parameters display detailed information about the type of Turbo Coding that is used in data bursts. Each coding type has trade offs between coding gain and bandwidth granularity of the bandwidth pool.

Columns:TPC Codec � The TPC codec (encoder-decoder) that is used for data bursts� You cannot edit this parameter for the CSC channel. It is displayed for

information only.� You can edit this parameter for the data bursts.

# Blocks� The number of blocks in each burst� For CSC only, enter 2 for symbol rates above 2.5 MegaSymbols/second.

# Bursts

For DATA bursts, the system computes the number of bursts.

For CSC only:� The number of CSC columns or bursts at the start of each frame� The default value is 1. You can enter a different value.� The number of CSC bursts must be the same on every terminal.

Signal Modulation � The modulation type that is used for data traffic:� Select QPSK or 8PSK.Note: � If the DATA bursts use 8PSK modulation, the signaling bursts (NBC,

CSC) continue to use QPSK.



Rows:DATA � The Demand Assigned Multiple Access (DAMA) pool operates on all carriers that are defined in the carrier definitions. Currently, one DAMA pool is available.� The DAMA pool starts immediately in the frame after the NBC and CSC

signaling channels.� The system inserts as many data bursts as possible until the end of the

frame.

CSC Bursts

Satellite longitudea Enter the geographic longitude for the location of the Geosynchronous

Earth Orbit (GEO) satellite, in units of Degrees, Minutes, and Seconds.

b Select E (east) or W (west) of the prime meridian.

Boot as Primary Reference NodeSelect this checkbox on only one node in the network � the primary reference node. This is the first node that starts transmitting over the satellite link.

When this node boots as Primary, this checkbox clears. To make the node boot as Primary again:� Select the checkbox again.Note: � If the terminal is already operating, the system ignores changes to this

parameter.

Configuring Terminal Parameters at the Primary Reference Terminal

3 Select Configure > Terminal.

4 Enter the terminal parameters:

Terminal NumberDefines the number of the terminal, and defines which CSC timeslot the terminal uses to contact the primary reference node.� Enter a number from 1 to the maximum number of nodes in the network.

The network can contain a maximum of 1000 nodes.� This number cannot be zero (0).� The number must be unique within the network. Nodes cannot use the

same number.

IF TypeThe Intermediate Frequency (IF) is defined by the modem hardware signature.� The possible values are 70 MHz or L-Band.� This information is not editable.

Signaling Carrier FrequencyThis parameter is the IF frequency of the signaling carrier of the network. This parameter shows the center frequency for Carrier 0.� This is the only carrier frequency that you enter at a non-reference

terminal.� You enter the frequency of the other carriers on the Carrier tab and only

at the primary reference node. See Configuring the Carriers on page 50.

Enter the center frequency of the carrier:� For L-Band, the center frequency must be between 950 MHz and

1525 MHz.� For 70 MHz, the center frequency must be from 50 to 90 MHz.

ODU Frequency Offset� For 70 MHz modems, enter a frequency offset to compensate for any

frequency offset of the local Outdoor Unit (ODU). The range is from -20 MHz to +20 MHz. The default is 0. The same offset applies to both TX and RX directions.



Note: � Define the VSATPlus 3 carriers only on the Primary Reference node

because the carriers are global to the VSATPlus 3 network. Configure the ODU Frequency Offset on the local VSATPlus 3 Terminals to add to the global value of the carrier frequency definitions and adapt to the local ODU frequency � Configuring Terminal Parameters at a Non-Reference Terminal on page 55.

� The 70 MHz modem filters pass frequencies only in the range from 50 MHz to 90 MHz, and cannot transmit or receive frequencies outside of that range. If a combination of the carrier frequency plus the ODU frequency offset falls outside of this range for any carriers, the terminal switches to the In-Network state. In that state, the terminal releases all bandwidth and remains manageable from the Primary VSATPlus 3 Terminal over the NBC and CSC. The operator at the Primary terminal can detect the change on the remote terminal from the On-line to In-Network state. Then, delete the carrier that was just added to bring the terminal back into the On-line state. Note that when the terminal switches to the In-Network state, you cannot manage it over the satellite link from the browser because all bandwidth has been released. However, the browser remains available from the Terrestrial port. When a carrier is defined outside the frequency range, the log records the alarm, "Carrier X is beyond limit when local ODU offset applied."

� For a CW (continuous wave test carrier), the ODU Frequency Offset also applies.

L-Band parametersOnly for L-Band, define the following parameters for both transmit (Tx) and receive (Rx) directions. For a detailed description, see Assigning Carrier Frequencies � L-Band Center Frequency on page 72.

Receive and Transmit Center Frequency� Define the center frequency of a 40 MHz band. The center frequency

must be between 950 MHz and 1525 MHz.Note: � The center frequency that you enter is the center frequency that the

modem uses to transmit and receive, and it must match the frequency that the ODU equipment expects.

Receive and Transmit Spectral Inversion� Activates spectral inversion on the transmit or receive links.

Receive and Transmit 10 MHz Reference Output� Select to send a 10 MHz reference signal to ODU equipment.

Receive and Transmit 24 V DC Output� Select to send 24 V DC to ODU equipment.

CAUTION!Risk of Equipment DamageIf you apply electric current to ODU equipment that is not equipped to accept it, you can damage that equipment.

local fade.

ULPCWhen enabled, UpLink Power Control (ULPC) automatically adjusts transmit power to overcome uplink fade in order to keep the signal power constant at the satellite. Total fade is the sum of the uplink and downlink fades. Uplink fade is derived from the total fade.a Select Enable ULPC.

b Enter the Maximum Power that ULPC can transmit. Normally, the ODU determines the maximum signal power that it can receive from the terminal. This value must be within the range of and greater than the nominal Transmit Power.

c Enter the Nominal Receive Level. This is the receive power level that the terminal expects to receive from its own signaling bursts when there is no fade. Set this value by monitoring the receive level at the local terminal with ULPC disabled, and when the sky conditions are clear (no fade).

TCP Accelerator� Enable Accelerator � Select to enable Protocol Enhancing Proxy (PeP)

for optimum performance of TCP sessions over the satellite link.� Enable Compression � Select to enable TCP compression by PeP. To

activate compression, select this Enable Compression and Enable Accelerator. This option affects only TCP traffic.

SNMP� You can configure and enable Simple Network Management Protocol

(SNMP) on any terminal that will be polled by an SNMP console. When enabled, an SNMP Agent starts on the terminal and listens for SNMP requests. The SNMP consoles are third-party modules and are not provided by PolarSat. VSATPlus 3 supports version 2c of the SNMP protocol.



� The Management Information Base (MIB) defines the list of parameters to query from a VSATPlus 3 Terminal. The details of the parameters in the MIB are in the file POLARSAT-VP3-MIB.txt. You can download the file and other standard MIBs that the terminal supports from: http://<ip address of the terminal>/snmp

a Enable the SNMP Agent so that it can respond to SNMP requests.The default User Datagram Protocol (UDP) port for the Agent is 161. You can change this port number to a number between 1 and 65535.You can also define a community name of up to 20 characters. The name is case-sensitive.

b To enable the SNMP Agent traps to generate and send SNMP traps:Configure an IP address and community name.Enable the trap destination. The default UDP port for the trap destination is 162. You can change this number to any number between 1 and 65535. Traps can go to multiple destinations.

VSATPlus 3 > Installation and Configuration > Configuring the Global Network

Configuring the Global NetworkYou can display the global parameters at every node, but you can edit them only at the primary reference node. If you change global parameters at a non-reference node, the system detects the change, and overwrites the changes by a download of the original values from the primary reference node.

Global parameters affect every node in the network and are the same on every terminal. Make sure that you configure the global parameters on the primary reference node. The primary reference node distributes the global parameters to every node in the network over the NBC or CSC signaling channel.



Before you start: � Configure the basic parameters of the VSATPlus 3 Terminal that is the

primary reference terminal � Configuring the Primary Reference Terminal on page 36.

� If not connected, connect to the user interface of the terminal that is the primary reference node � Connecting to the User Interface on page 35.

Assigning an IP Address to Each Terminal

The VSATPlus 3 network centrally manages the IP addresses of all terminals and distributes the addresses to all terminals.

2 To configure the IP network, define the IP address of each VSATPlus 3 Terminal in the network. Click Configure > Route.a Add an entry in the table and select the Terminal entry type.

b Enter the terminal number, IP address, and Classless Inter-Domain Routing (CIDR) value.

Note: � The other columns in the IP Route table � Gateway and Default Terminal

� apply only to Static Routing. � The Terminal Name is optional. It supports UTF-8 character sets for

internationalization.

c Click the checkmark to save the local edits.

d When you define all of the terminals, click Save the Configuration to save all of the definitions in the terminal.

Selecting the Routing Protocol

3 In Routing Protocol, select either:� None (default) � Routes between terminals are static and fixed. You

must manually define the routes in the routing table. Go to Static Routing on page 43.

� OSPF � Open Shortest Path First is an adaptive routing protocol for IP networks. The terminal communicates the current topology of the network to other OSPF-enabled routers, and can adapt to changes or faults. Go to Dynamic Routing on page 48.

Static Routing To configure the IP network to use static routing:

4 Turn off dynamic routing on the satellite subnet and on the LAN port of each terminal:a For the satellite subnet from the Primary terminal, click Configure >

Route.Set the Routing Protocol to None (default).Click Save the Configuration.

b For each terminal, click Configure > Terminal.To disable dynamic routing over the LAN interface, set the Routing Protocol to None (default).Click Save the Configuration.

5 Configure a default route for each terminal.

6 Configure additional IP Routes to other subnets.

Default Route7 How you configure a terminal depends on whether the default route

(address/CIDR: 0.0.0.0/0) of the terminal is on the LAN or over-the-air (satellite).� When the default route is on the LAN side of the terminal, add another

IP Route entry to configure the default route to the associated Gateway IP address. The entry is a Route type.

� When the default route is over the satellite side, configure the route in the Default Terminal field of the Terminal entry.



LAN Gateway Default Route � A default route (0.0.0.0/0) to a LAN gateway is typical for nodes that are at the same location as Internet gateways. These nodes provide access to the Internet for the other VSATPlus 3 Terminals in the network. When you configure a terminal with a default LAN gateway, make sure that the Default terminal is set to � (dash = none). This setting indicates that the terminal does not have a default route that is over-the-air.

CAUTION!Risk of Unexpected BehaviorIf you configure both a default route over a LAN gateway and a default route over-the-air, you can cause routing loops and unexpected routing behavior. In the example network, Entry 1 indicates that Node 15 has a Default Terminal value of �, which means that the default IP Gateway is on the LAN side, rather than over-the-air. As a result, Terminal 15 must have another entry � entry 2 of type Route � to specify the default route on the LAN side.

Default Terminal (over-the-air) � If you set the Default Terminal to a non-zero value, the terminal configures a default route over-the-air to the specified terminal. To remove a default route, set the Default Terminal to � (dash). In the example network, Terminals 6 and 10 are configured to use Terminal 15 as the default gateway. Any IP packet that arrives at these terminals on their LAN port that does not match a specific route is forwarded over-the-air to Node 15.

Additional IP Routes8 You can define additional routes on the LAN side of individual VSATPlus 3

Terminals:a Create an IP route entry of type Route.

b Define the terminal number, the subnet (IP address and CIDR), and the Gateway IP address to which the terminal forwards the matching packets. The Gateway IP address has to be in the same subnet as the defined terminal.

c Click Save the Configuration.

The route table for the example network follows:� Entry 1 � The IP address of Terminal 15, which has no Default Terminal.

As a result, it should have a route entry to specify an IP Route on the LAN port.

� Entry 2 � A route associated to Terminal 15 that specifies to forward the packets that match the default route (0.0.0.0/0) to the Gateway address 172.16.100.1

c In the confirmation dialog box, click OK.



Network Mask (CIDR)� Enter the network mask of the local subnet in Classless Inter-Domain

Routing (CIDR) format (0 to 32).� The Mask defines the subnet address that is routed.

Default Terminal� The Default Terminal field is similar in concept to the Default Route. To

route packets to the Internet, each terminal has either a Default Terminal (for routing over-the-air) or an explicit IP Gateway on the terrestrial Ethernet port.

In the example network:� Terminals 6 and 10 define Terminal #15 as the Default Terminal.� Terminal 15 connects to the Internet Service Provider (ISP) on the

terrestrial side, so it does not have a Default Terminal (set to �).

For Route

Terminal Number� Enter the number of the terminal for the associated route.

In the example network:� Entry 5 defines a subnet that is beyond Terminal 6: 172.16.206.1/24.� Entry 2 defines the default route that goes to the Internet.

Route NameEnter a name that describes the purpose of the route:� Up to 16 characters long� UTF-8 is supported for international character sets.� <, >, and & are not allowed.

IP Address� Enter the IP address of the subnet that is beyond the terminal.

Network Mask (CIDR)� Enter the network mask of the subnet that is beyond the terminal.

Gateway IP Address� The IP Gateway field indicates the IP address of the gateway that

continues the routing.� If a packet is addressed to another subnet, then it must be forwarded

to an IP Gateway. Typically, an IP Gateway belongs to multiple subnets and has an IP address in each subnet. In this field, you must enter the IP address of the gateway that belongs to the same subnet as the terminal.

In the example network:� Entry 5 is for a subnet, 172.16.206.x/24, that is beyond Terminal 6.

12 Click Save Route.You return to the Route page.

CAUTION!Risk of Loss of ConnectivityIf the IP address of an existing terminal is changed, then all browser sessions to that terminal are terminated.




Dynamic Routing

If you enable dynamic routing, you must enable it over both the satellite (over-the-air) and over the LAN interface of each terminal.

OSPF Notes� For most networks, set both the LAN and satellite OSPF areas to 0.0.0.0� You do not need to enable OSPF on the LAN side of terminals that do not

have other OSPF-enabled routers. This is typical at branch office or Small Office Home Office (SOHO) sites.

Enabling OSPF on the Satellite Interface14 Over-The-Air Routing � The over-the-air routing is common to all

terminals:a For each terminal, click Configure > Route.

b Set Routing Protocol to OSPF.

c Area � Configure the OSPF Area in dotted decimal notation. To configure the Air segment to be part of the OSPF backbone area, use 0.0.0.0

d Cost Over Satellite � Set a cost for the satellite segment. OSPF selects a path through the network that has the lowest cost. If the VSATPlus 3 network is being used as a backup network, set the cost to be higher than any terrestrial pathways. If the VSATPlus 3 network is the only network that connects remote sites, the cost is irrelevant.

e Enable Static Route Redistribution � Select to allow OSPF routers to see static routes that are defined at the terminal. Otherwise, configured static routes are visible only from the VSATPlus 3 Terminal where they are defined.

f Disable TCP Accelerator Globally � Select to correctly balance TCP traffic flow. With OSPF and depending on the network topology, some routes may be asymmetric where the forward path is different from the reverse path. If this occurs, the TCP accelerator does not work. In this case, disable the TCP accelerator globally on all terminals.

g Click Save the Configuration.

Enabling OSPF on the LAN Interface15 LAN Routing � Configure the Local Area Network (LAN) routing separately

for each terminal.a For each terminal, click Configure > Terminal.

b Set Routing Protocol to OSPF.

c Configure the OSPF Area in dotted decimal notation. To configure the LAN segment to be part of the OSPF backbone area, use 0.0.0.0

d Set a cost for the LAN segment. The value depends on the reference bandwidth used by other routers on the LAN segment. If other routers use 1,000,000,000 (1 Gbps Ethernet), set the LAN cost to 10 to represent the 100 Mbps fast Ethernet connection of the VSATPlus 3 Terminal. If the LAN routers use 100,000,000 (100 Mbps Fast Ethernet), set the cost to 1.

e Click Save the Configuration.

Configuring IP Links

16 To configure IP Links, click Configure > Link.

An IP Link is a connection from one node to another. The direction of the connection is important. Normally, two nodes have a pair of IP links, one link for each direction: A to B and B to A.

Initially, an IP link has no allocated bandwidth. As packets arrive, the node allocates timeslots from the bandwidth pool, and transmits packets to the destination node. For each IP link, you can define the following parameters:



MINThe minimum bandwidth (MIN) remains allocated while the two nodes are up, even if no traffic needs this bandwidth. MIN treats pre-assigned bandwidth in a similar manner to with Permanently Assigned Multiple Access (PAMA).� If one of the nodes on the link goes down, then the bandwidth is released

to the bandwidth pool. When the system detects that the two nodes are up, it allocates the MIN bandwidth again.

� The range for the MIN parameter is from 0 to the maximum number of bursts on the carrier. The MIN must be less than or equal to the CIR.

CIRThe CIR defines the bandwidth to allocate to the link when the traffic load needs it.� The system allocates bandwidth in priority up to the limit of CIR, and

guarantees bandwidth only when the network is not over-subscribed.� The range for CIR is from MIN to the maximum number of bursts on a

carrier.� The value of CIR always includes the value of MIN.

EIRThe EIR is bandwidth in excess of the CIR that the system can allocate whenever bandwidth is available in the bandwidth pool.� The total bandwidth that the system can allocate to a link is CIR + EIR.

The total bandwidth is not MIN + CIR + EIR.� The range for EIR is from 0 up to the maximum number of bursts on a

carrier. However, the sum of CIR + EIR must be less than or equal to the maximum number of bursts on a carrier.

Note: � The system allocates bandwidth in units of bursts. The definition of the

bandwidth pool specifies the burst size. The MIN, CIR, and EIR are in units of bits-per-second (bps), and the BoD server rounds up the burst size to the nearest unit of burst.

� In a network of n terminals, a fully-meshed network can have many connections. You do not have to define the MIN, CIR, and EIR parameters for each of the links. Instead, you can define explicit parameters for an IP Link, and then define default IP Link parameters for any link without explicitly defined parameters.

� The MIN, CIR, and EIR Bandwidth are allocated in a pro-rated manner. If the network is oversubscribed, then each link has the same percentage of MIN, CIR, and EIR parameters.

� The CIR bandwidth is always allocated first and released last.

17 In addition to the MIN, CIR, and EIR parameters, you can configure the following Advanced Parameters to control the bandwidth allocation and release:

Low Bandwidth ThresholdThe Low Bandwidth Threshold is a percentage of the currently allocated bandwidth that defines when to start to release bandwidth.� When the usage of the currently allocated bandwidth decreases below

this threshold, and during the last N seconds that you define in the Decrease Timer, the system starts to release bandwidth.

� For example, if the Decrease Timer is 6 seconds, and the Low Bandwidth Threshold is 35 %, the system releases bandwidth every 6 seconds when the usage of the currently allocated bandwidth is below 35 %.



High Bandwidth ThresholdThe High Bandwidth Threshold is a percentage of the currently allocated bandwidth that defines when to allocate more bandwidth, up to the limit of CIR + EIR.� When the usage of the currently allocated bandwidth increases above

this threshold for a sampling interval of approximately 2 seconds, the Bandwidth Manager requests more bandwidth.

CIR Increase Ratio and CIR Decrease RatioThe CIR Increase Ratio and CIR Decrease Ratio together define the percentage of CIR that gets allocated and released for every request.� For example, in networks where the configured CIR is small � for

example, 64 kbps � the system can allocate CIR entirely to 100 %, as soon as the first packet arrives on the link.

� Conversely, in networks where the configured CIR is large, the system can allocate the CIR gradually until the CIR limit is reached. Then, the system starts to allocate EIR bandwidth, if the EIR is greater than 0.

� Similarly, you can define the amount (in %) by which to release the bandwidth.

EIR Increase Ratio and EIR Decrease RatioThe EIR Increase Ratio and EIR Decrease Ratio together configure the amount of bandwidth to allocate or release from the excess bandwidth in the bandwidth pool.� Often, IP Links can be configured with a small CIR � for example, 32 or

64 kbps � and a large EIR (as large as the carrier permits). This allows multiple IP Links to share the excess bandwidth in the pool.

� These two parameters configure the percentage of the EIR that is allocated and released when thresholds are crossed. Since the EIR can represent a large amount of bandwidth, the bandwidth increase can be small � for example, 10 % � while bandwidth decreases can be done more rapidly � for example, 40% each time.

Decrease TimerThe Decrease Timer sets the amount of time that the bandwidth usage is below the Low Bandwidth Threshold, before the system starts to decrease the bandwidth.� PolarSat recommends that you set the value to 6 seconds or more, but

no less than 6 seconds.


Configuring the Carriers

The carrier definitions defines the frequency offset for each carrier, in the range of +/� 20 MHz, starting from carrier 0. Define the frequency offsets of each carrier as seen at the satellite and, for L-Band terminals, independently of the transmit and receive spectral inversion settings for each terminal.

19 Select Configure > Carrier.Note: � The Carriers page displays Carrier 0 even though you cannot configure

it from this page. You configure Carrier 0 in the Signaling Carrier Frequency on page 38 parameter.



20 Define up to 31 carriers, numbered from 1 to 31:

21 To define the carrier frequency, enter a frequency offset from -20 to +20 MHz.

22 Click OK.


Configuring Multicast Links

Multicast links are configured on and controlled from the Primary Reference terminal for the entire network. If you need to configure or enable a multicast link remotely, remotely connect over the satellite link to the Web interface of the reference terminal. Then, you can control (enable or disable) the multicast links.

In general, you first configure a multicast link and save the configuration. Then, you enable the multicast link and save the configuration.

You cannot change the configuration of an active multicast link. First, you must disable the active multicast link. Then, you can change the configuration.

Multicast traffic has a Time-to-Live (TTL) parameter that defines the maximum number of routers that the multicast packets traverse. To send multicast packets over a satellite network, set the TTL to at least 3, because the TTL count decreases by 2 for each satellite link (between a pair of terminals).

CAUTION!Risk of Signal LossMulticast links have higher priority than unicast links. When multicast links are enabled, the system allocates bursts to the multicast links. If needed, this removes bursts from the unicast links and can disrupt the unicast traffic.

The bandwidth for multicast links is either all allocated or not at all. Multicast links do not have a partial amount of bandwidth allocated.

24 Select Configure > Multicast.

Tx TerminalThe terminal number that transmits the multicast bursts. When the multicast link is enabled, this terminal sends an Internet Group Management Protocol (IGMP) packet to the upstream router on the LAN port so as to register with the associated multicast stream, and start transmitting the stream in the multicast bursts over the satellite link.

RX GroupA list of terminals that receive the multicast stream: a sequence of terminal numbers, separated by commas; or a range of terminal numbers separated by a hyphen (-). To prevent multicast loops, the transmitting terminal number cannot be part of the RX group.

Source IPThe IP address of the device that originates the multicast stream.

Destination IPThe destination multicast IP address of the multicast stream; must be in the range from 224.0.0.0 to 239.255.255.255.

28 To configure a VSATPlus 3 Terminal to be a non-reference node, see Configuring a Non-Reference Terminal on page 54.


VSATPlus 3 > Installation and Configuration > Configuring a Non-Reference Terminal

Configuring a Non-Reference TerminalWhen you configure a non-reference VSATPlus 3 Terminal, first you configure the node locally with the minimum number of parameters it needs to join the network. Then, the terminal downloads from the primary reference terminal the parameters that are common to all nodes. These parameters are called the parameter lists or the lists.

The network and terminal parameters are stored locally on each terminal. You can configure these parameters from the web-based user interface either from a remote node over the satellite link, or from the LAN port at the terminal.



Before you start: � Configure the VSATPlus 3 Terminal that is the primary reference terminal

� Configuring the Primary Reference Terminal on page 36.� Configure the network parameters � Configuring the Global Network on

page 42.� Install the VSATPlus 3 Terminal that will be the non-reference terminal �

Installing a VSATPlus 3 Terminal on page 32.� Connect to the user interface for the terminal, see Connecting to the User

Interface on page 35.

CAUTION!Risk of Failed ConfigurationBecause the VSATPlus 3 Terminal ships from the factory with a pre-configured IP address of 192.168.200.1, you cannot configure multiple terminals on the same LAN. If you need to connect the terminals on an IF loop (that is, not over the satellite link), make sure that the terminals are on different LANs.

Configuring Network Parameters at a Non-Reference Terminal

1 Select Configure > Network.

2 Configure the following parameters to prepare the initial configuration. These parameters must be the same on every node in the network, but you must enter them on each terminal to get the network to recognize the terminal, and so that the terminal acquires the network.

Network SizeEnter the number of terminals in the network� The system uses this parameter to define the number of CSCs that are

needed for signaling (NBC and CSC bursts).� The range of values is from 1 to 1000.� The value must be the same on all terminals in the network.

Symbol Rate� Enter the number of symbols that occur each second. Each symbol

carries 2 bits for QPSK, or 3 bits for 8PSK.� The range of values is from 128,000 to 5,000,000 symbols/second.

Frame TimeDefines the duration of one TDMA frame in the network:� Select 20, 30, or 40 ms (default) frames.



Frames per Superframe� Enter the number of frames for each superframe in the network. A

superframe is a group of frames.� The range of values is from 10 to 60 frames/superframe.� Typically, you select 30 or 60 frames/superframe.

Secondary Ref TerminalDo not edit this parameter on a non-reference node.� This parameter is downloaded from the primary reference node when

the non-reference node joins the network.� This parameter defines the node that operates as the secondary

reference node in the network.

Signal ModulationThe modulation type that is used on the DATA bursts:� When the DATA bursts use 8PSK, the signaling bursts (NBC and CSC)

continue to use QPSK.� You cannot edit this parameter on a non-reference node. It is displayed

for information only.

TPC parametersDo not configure these parameters on a non-reference node.� These parameters display detailed information about the type of Turbo

Coding that is used in data bursts.

# BurstsFor CSC only:� The number of CSC columns or bursts at the start of each frame� The default value is 1. You can enter a different value.� The number of CSC bursts must be the same on every terminal.

Satellite longitude� Enter the geographic longitude for the location of the GEO satellite, in

units of Degrees, Minutes, and Seconds.

Boot as Primary Reference Node

CAUTION!Risk of Failed ConfigurationDo not select Boot as Primary Reference Node on a non-reference node. If the terminal is operating, this setting is ignored. Otherwise, this setting forces the terminal to boot as a primary reference.


Configuring Terminal Parameters at a Non-Reference Terminal

4 Select Configure > Terminal.

5 Enter the terminal parameters:

Terminal NumberDefines the number of the terminal, and defines which CSC timeslot the terminal uses.� Enter a number from 1 to the maximum number of nodes in the network.

The network can contain a maximum of 1000 nodes.� This number cannot be zero (0).� The number must be unique within the network. Nodes cannot share

the same terminal number.



IF TypeThe Intermediate Frequency (IF) is defined by the modem hardware signature.� The possible values are 70 MHz or L-Band.

Signaling Carrier FrequencyThis parameter is the IF frequency of the signaling carrier of the network.� Enter the center frequency of the carrier. This parameter is the same

as on the primary reference terminal.� For L-Band, the center frequency must be between 950 MHz and

1525 MHz, and must be within +/- 20 MHz of the Rx Center frequency.� For 70 MHz, the center frequency must be between 50 MHz and

90 MHz.

ODU Frequency Offset� For 70 MHz modems, enter a frequency offset to compensate for any

frequency offset of the local ODU. The range is from -20 MHz to +20 MHz. The default is 0. The same offset applies to both TX and RX directions.

Note: � Define the VSATPlus 3 carriers only on the Primary Reference node

because the carriers are global to the VSATPlus 3 network. Configure the ODU Frequency Offset on the local VSATPlus 3 Terminals to add to the global value of the carrier frequency definitions and adapt to the local ODU frequency � Configuring Terminal Parameters at the Primary Reference Terminal on page 38.

L-Band parametersOnly for L-Band, define the following parameters for both transmit and receive directions. For a detailed description, see Assigning Carrier Frequencies � L-Band Center Frequency on page 72.

Receive and Transmit Center Frequency� Define the center frequency of a 40 MHz band. The center frequency

must be between 950 MHz and 1525 MHz.Note: � When you use spectral inversion, the center frequency that you enter

� The Management Information Base (MIB) defines the list of parameters to query from a VSATPlus 3 Terminal. The details of the parameters in the MIB are in the file POLARSAT-VP3-MIB.txt. You can download the file and other standard MIBs that the terminal supports from: http:// <ip address of the terminal>/snmp

a Enable the SNMP Agent so that it can respond to SNMP requests.The default User Datagram Protocol (UDP) port for the Agent is 161. You can change this port number to a number between 1 and 65535.You can also define a community name of up to 20 characters. The name is case-sensitive.

b To enable the SNMP Agent traps to generate and send SNMP traps:Configure an IP address and community name.Enable the trap destination. The default UDP port for the trap destination is 162. You can change this number to any number between 1 and 65535. Traps can be sent to multiple destinations.



Routing Configuration for the LAN Porta Protocol � Select either:

Static � See Configuring the Global Network on page 42 > Static Routing on page 43.OSPF � See Configuring the Global Network on page 42 > Dynamic Routing on page 48.For Open Shortest Path First (OSPF), configure:Area � Enter the OSPF Area on the LAN port in dotted decimal notation. To configure the LAN segment to be part of the OSPF backbone area, enter 0.0.0.0.Cost � Enter a cost for the LAN segment. The value depends on the reference bandwidth used by other routers on the LAN segment. If other routers use 1,000,000,000 (1 Gbps Ethernet), set the LAN cost to 10 to represent the 100 Mbps fast Ethernet connection of the VSATPlus 3 Terminal. If the LAN routers use 100,000,000 (100 Mbps Fast Ethernet), set the cost to 1.


7 To configure other non-reference terminals, repeat this procedure for each terminal.

8 After the network is operating, you can edit the QoS rules. See Configuring QoS Rules on page 59.


VSATPlus 3 > Installation and Configuration > Configuring QoS Rules

Configuring QoS RulesQuality of Service (QoS) rules classify IP packets and assign a transmission priority for the satellite link. The 8 priority levels are from 0 to 7; 0 is the highest priority. You cannot specify bandwidth limits on different traffic types.

Normally, you do not need to configure QoS rules to make the VSATPlus 3 network operational. Predefined QoS rules allow the network to operate with a set of QoS rules. If the default QoS rules are not suitable, and after the network is operating, you can edit or delete any of the rules, or create new rules.

When a packet arrives at the terrestrial port, the system examines it for a match. It examines the packet from the first rule at the top of the list of QoS rules, then with each rule in descending order, until the packet matches the criteria specified by a rule. When there is a match, the system assigns the priority of the rule to the packet. If the packet passes through every rule without having a match, then it is assigned priority 7 (lowest priority).

QoS statistics show the number of packets and number of bytes that each rule has matched.

Predefined QoS Rules

Priority Description

0, 1 Alarms� Priority 0 and 1 do not have pre-defined rules. Typically,

only alarms travel at these priorities.

2 VoIP DSCP� All IP packets that have the Differentiated Services Code

Point (DSCP) field set to 46 (0x2E) for Expedited Flow (EF), or 40 (0x28) for IP precedence 5, are assigned priority 2.

� The primary targets are Voice over Internet Protocol (VoIP) signaling and voice packets.

3 DNS UDP� All User Datagram Protocol (UDP) packets that have port 53

as a source or destination port are assigned priority 3.� The well known port for the Domain Name System (DNS)

is 53.

4 HTTP, HTTPS, SSH� All packets for the interactive protocols HTTP, HTTPS, and

Secure Shell (SSH) are assigned priority 4.� These interactive protocols use TCP sessions.

5 Non-interactive TCP� All TCP packets, other than HTTP, HTTPS, and SSH, are

assigned priority 5.� Priority 5 is intended for non-interactive TCP applications,

such as email transfer.

6 UDP� All UDP packets are assigned priority 6.

7 Other� All remaining packets are assigned priority 7. For example,

all "ping" packets are assigned priority 7.



Before you start: � Configure the VSATPlus 3 Terminal that is the primary reference terminal

according to Configuring the Primary Reference Terminal on page 36.� Configure the network parameters according to Configuring the Global

Network on page 42.� Configure the VSATPlus 3 Terminals that are the non-reference terminals

according to Configuring a Non-Reference Terminal on page 54.� QoS rules are not managed globally; the rules can be different on each

terminal. Connect to the user interface for the terminal � Connecting to the User Interface on page 35.

1 Select Configure > QoS.The page displays QoS rules in descending order of processing.

2 You can create, edit, or delete rules. In the Action column, click the Edit icon for the rule.

3 Edit the Priority, Description, and Rule specification for each rule.

Priority � Values from 0 to 7; 0 is the highest priority.

Description � A free-text comment that explains the actual rule. The description is saved in the configuration, but is not used by the system. Enter a description to record the purpose of the rule.

Rule � Contains the rule that classifies the packets. The rule associates values to the fields of the IP packet to find a match. When IP packets arrive, the system examines each to verify if any fields match values in the rule. If matched, the system assigns the packet the priority for that rule. a You can define the following fields of the IP packet in a rule: DSCP,

Protocol, Source IP address or subnet, Destination IP address or subnet.

b You can define a compound rule that requires that any or all fields must match to assign a priority.

Tip: � For a packet to match and be assigned the associated priority, the packet

must meet the conditions defined by each of the four fields. So, if one field is not important for a rule, select the condition that all packets must meet that condition. For example, if the DSCP field is not important for a rule, select Any DSCP for that rule. This ensures that all packets meet the condition for the DSCP field, regardless of the value in that field.

4 From the Protocol rule, select either:� Any Protocol � Does not examine the Protocol field for a match. All

protocols match.� Protocol is � The Protocol field in the IP packet must have the selected

<protocol> value: ICMP, TCP, UDP, or a <value>. If you select <value>, define the protocol as a number from 1 to 255. For the TCP and UDP protocols, define a source or destination <port range> (see below).

� Protocol is not � The Protocol field in the IP packet must not have the selected <protocol> value: ICMP, TCP, UDP, or a <value> from 1 to 255. For the TCP and UDP protocols, define a <port range>.

� <port range> � Define two numbers: the second number must be equal to or higher than the first number. Each number can be from 0 to 65535. To match a single port, set the first and second port number to the same value. For the port range, select:

Customer Service Line ... on page 76



VSATPlus 3 > Assigning Carrier Frequencies � L-Band Center Frequency

Assigning Carrier Frequencies � L-Band Center FrequencyCarrier frequencies in VSATPlus 3 networks are defined as offsets relative to the center frequency of the transponder. This allows a mix of 70 MHz and L-Band terminal types to share a common carrier configuration, with each carrier defined by an offset. The frequencies can be VHF (70 MHz) or L-Band.

To participate in the network, the center frequency of the terminal must be configured correctly:� For 70 MHz terminals, no setup is required, because the center frequency

is 70 MHz.� For L-Band terminals, the center frequency must be set correctly on both

Tx and Rx sides.

Mixed network of 70 MHz and L-Band terminals

In a mixed network, the center frequencies must be consistent between the 70 MHz terminals and the L-Band terminals.

1 First, determine the RF frequencies that correspond to a 70 MHz carrier. Do this for both Rx and Tx sides.

2 The L-Band center frequencies (fCF_TX (transmit) and fCF_RX (receive) in the following formula) for a terminal must correspond, and are calculated from the value of the Local Oscillators (LO) for the Low Noise Block (LNB) (fLO_LNB) and Block Up-Converter (BUC) (fLO_BUC).

If the ODU equipment is non-inverting, calculate the frequencies by:� fCF_TX = fRF_UL � fLO_BUC� fCF_RX = fRF_DL � fLO_LNB

If the equipment is inverting, calculate the frequencies by:� fCF_TX = fLO_BUC � fRF_UL� fCF_RX = fLO_LNB � fRF_DL

Where:� fRF_UL � RF frequency of the Up Link� fRF_DL � RF frequency of the Down Link� fLO_BUC � LO frequency of the BUC� fLO_LNB � LO frequency of the LNB� fCF_TX � Center frequency for TX� fCF_RX � Center frequency for RXWhen the L-Band center frequencies are well configured, a carrier configured with an offset of 0 MHz, appears at 70 MHz on the 70 MHz terminals, and at the L-Band center frequency on L-Band terminals.

L-Band-only network

If a network consists only of L-Band terminals, either:� Proceed as in the Mixed network of 70 MHz and L-Band terminals. Set the

central frequency to the value that corresponds to a 70 MHz carrier transmitted by a 70 MHz terminal, as if such a terminal is in the network. This allows the future addition of a 70 MHz terminal to the network without re-configuration of the network.

� Otherwise, select arbitrary RF center frequencies (fRF_UL and fRF_DL) to define the center frequency in the network, and use the formulas in step 2 to calculate the corresponding L-Band center frequencies.Important: Once the RF center frequencies are selected, they apply to all terminals in the network and cannot be changed easily.

Select the RF center frequencies, according to the following constraints:� Normally, the frequencies are a multiple of 1 MHz. However, if the uplink

and downlink frequency of the transponder are not separated by a multiple of MHz, you can configure only the TX L-Band center frequency as a fraction of MHz.

� fRF_UL corresponds to fRF_DL when down-converted by the transponder.� Choose the frequency so that all carriers in the network are within

+/� 20 MHz of the center frequency.


VSATPlus 3 > Assigning Carrier Frequencies � L-Band Center Frequency

Note: � The chosen RF center frequencies become a reference for the network.

All carriers are configured as offsets from this reference. Use the same RF center frequency on all terminals in a network when you calculate the L-Band center frequency.

For example:� fRF_UL = 6042 MHz = RF frequency of the Up Link of the network� fRF_DL = 3817 MHz = RF frequency of the Down Link of the network� fLO_BUC = 4900 MHz = LO frequency of the BUC for one site� fLO_LNB = 5150 MHz = LO frequency of the LNB (Rx spectral inversion)

The computed L-Band center frequencies are:� fCF_TX = 1142 MHz = L-Band center frequency for Tx� fCF_RX = 1333 MHz = L-Band center frequency for Rx
