Requirements of the Network

YES Dedicated Network A dedicated network always consists of equipment of one type, e.g. only Gx-CNET-LAN

YES Non Dedicated Network with agreed data rates

With agreed data rates the sum of all data rates required is about 60% of the maximum data rate possible

YES Non Dedicated Network with QoS (Quality of Service)

QoS controls the data stream in the network and ensures, that the speech packets are delivered within the demanded time

NO Non Dedicated Network wit-hout QoS (Quality of Service)

99 % of all Corporate Networks, that were developed before the year 2000, are Non Dedicated Networks!

IP-Addresses and Ports:■ Each Gx-CNET-LAN must have a fixed IP-address■ The communication to the central needs Port 4000 (=16384 decimal), 4001

(=16385), 4002 (=16386) and 4003 (=16387) (configuration firewall / router)

Required Bandwidth:The required bandwidth depends on the desired number of speech links(see below). The minimum bandwidth is 96 kBit.

Maximum Delay■ Maximum delay 100 ms■ Delay-Jitter not above 50 ms

Speech ChannelsThe maximum number of conversations depends on four factors:

■ The available bandwidth (maximum 10 MBit can be used)■ The number of conversations the Gx-CNET-LAN can handle■ Compressed or uncompressed conversations■ All Calls / Radio Conferences with 3.5 or 7 kHz

Required BandwidthRequired Bandwidth incl. protocol overhead, for upload/download each:

Number of Conversations per Gx-CNET-LANThe easiest way to calculate the number of possible conversations is the fol-lowing “point system“:Per card Gx-CNET-LAN 32 points are available for speech transmission, aconversaion requires the following number of points:

Compressed conversationsEach Gx-CNET-LAN can compress a maximum of 3 conversations/all calls/radio conferences/music channels, for this reason this card is useable onlyfor 3 conversations/allcalls/radio conferences/music channels. Compressingcan be activated per Gx-CNET-LAN (for all conversations/all calls of thiscard), see ”Programming CCT” on page 16.

Setting the system numbersEach housing must be given a unique number.

There are two methods for numbering the housings:■ With the DIP-switches on the G7-GEP (GE 700) or on the motherboard of

the GE 200 G2-GEM (for a maximum of 14 housings). This is the easiestmethod, because the PC does not need to be connected to each singlehousing.

■ With the program CCT, e.g. for more than 14 housings or if the pro-gramming should be prepared in advance for a central.

Attention: The standard calling numbers, that are automatically allocatedfor the housings (see ”Switch position” on page 14), must be changed byprogramming if more than 9 housings are connected. Otherwise three- andfour-digit numbers beginning with the same digits would occur (e.g. 110 inhousing no. 1 and 1101 in housing no. 11).

Setting the numbers with DIP-switches1. Initialise each housing with the desired number (1 to 14):

- Set the DIP-switches 1 to 4 to “ON“.- Switch the central off and on.- Set the desired number (switch position see below).- Switch the central off and on.Attention: Initialising the central resets the programming.

2. Connect the PC to any housing of the central and read out the pro-gramming of the central with the program CCT. Now all cards are recogni-zed correctly and the central can be programmed as usual.After the network has been configured, PC can be connected to any hou-sing, all housings are programmed like a single central (menu “Central -Receive“, in the window “Central“ all housings have to be selected).

Attention: initializing the central resets the programming.

1. Select the function “Cards“ in the folder “Central“. Click on the button“Add Central“. Select the radio button “GE 700“ or “GE 200“ at “Central-Type“, enter the desired number at “Central-Number“ and acknowledgewith “Ok“.

2. Select the button “Add Central“ again. At “Central-Type“ select again“GE 700“ or “GE 200“, enter the next number at “Central Number“ andacknowledge with “Ok“. Repeat this procedure for all further housings. At“Central-Description“ at the top right side of the screen an optional textcan be entered for each housing.

3. Select “Initialize...“ in the menu “Central“.

4. Connect one housing after the other to the PC and select “Initialize...“. Inthe left field “Central No.“ the current number of the central is shown. En-ter the desired central number in the field “New No.“ and click on “Initial-ize“.

As soon as the number is transferred, the number appears also at“CentralNo.“.

5. Read out the programming of the central (menu “Central - Receive“, inthe window “Central“ all housings have to be selected). Now all cards arerecognized correctly and the central can be programmed as usual.

IP-Addresses, Subnet masks, Compression

Own IP Address■ Each Gx-CNET-LAN must be given a fixed and unique IP address, the IP

addresses are assigned by the network administrator.■ An IP address (“Internet Protocol“) consists of four numbers between 0

and 255, separated by dots (e.g. 192.168.0.195). Each network componentmust have a unique IP address.

Subnet mask■ Subnets are network segments that are connected with network devices

like e.g. Routers.■ For identification of a subnet a subnet mask is used. Like the IP address a

subnet mask consists of four numbers between 0 and 255, separated bydots (e.g. 255.255.255.0).

■ These decimal values result from a 32-bit binary number. All bits with va-lue 1 must be equal in all IP adresses belonging to this subnet.

■ The subnet mask specifies which portion of an IP address represents thenetwork ID (for identification of the subnet) and which portion representsthe host ID (for identification of single network components).

■ A common subnet mask is 255.255.255.0, which specifies:- The first three decimal numbers of all IP adresses inside this subnet

must be equal (network ID).- The last decimal number identifies the single network cards (host ID).

Router IP addressAll centrals in other subnets are addressed over the IP address of the Router.(see also ”Examples” on page 21). Router IP address and own IP address must be in the same subnet.If all Gx-CNET-LAN are in the same subnet, no Router IP address has to beentered.

VLAN-IDA VLAN-ID is required only, if the Gx-CNET-LAN is in a virtual network. TheID is entered as decimal number between 1 and 1023.It is also possible to create a VLAN by configuring the VLAN directly at theswitch (see ”Connection without IP Network (Test Systems)” on page 19).Therefore no VLAN-ID has to be entered.

Bandwidth in kBitThe standard setting 10240 kBit is valid, if at least 10 MBit bandwidth of thenetwork are available for the Gx-CNET-LAN. In networks with lower band-width or if only a part of the bandwidth is available, the bandwidth of the Gx-CNET-LAN can be adapted accordingly.

Data bandwidth in kBitWAN:In this combo-box the bandwidth which is used for data packets that leavethe Gx-CNET-LAN cards can be defined. When the bandwidth is reduced,the packets leave the cards with a larger time period between them. Thisprevents a „Packet-burst“ which can lead to a queue overflow at the router.The packets lost in this case can decrease the quality of speech and connec-tion.

LAN:With network components in local networks almost no effect.

G.722 CompressedIn networks with low bandwidth it may be necessary to transfer the conver-sations compressed. If the check box “G.722 Compressed“ is activated, allconversations, All Calls, radio conferences and music channels of this Gx-CNET-LAN are compressed.As a maximum of 3 conversations/All Calls can be compressed, only 3 con-versations/All Calls can be held at the same time from this card.

Attention with several centrals with different settings!If one network card is set to “Compressed“ and the other network card not,conversations or All Calls will always be compressed. Example:■ Central A: Gx-CNET-LAN not compressed■ Central B and C: Gx-CNET-LAN compressed

Central A can have only 3 conversations/All Calls with central B and C at thesame time, because the Gx-CNET-LAN of central A can compress only 3 con-versations/All Calls.

MAC AddressThe MAC address is displayed only in CCT, but cannot be changed.Every Gx-CNET-LAN has a worldwide unique MAC address (“Media AccessControl“), consisting of six 2-digit hexadecimal values, e.g.: “00 0C AB 01 3A28“.■ The first three values “00 0C AB“ are a worldwide unique identifier for our

network products. This number has been assigned to us from the “Insti-tute of Electrical and Electronics Engineers“ (IEEE).

■ The last three values are assigned by us to each Gx-CNET-LAN in a uniqueway.

Define the Connections■ Open the folder “Gx-CNET-LAN“ in the tree structure and click on one of

the centrals. Right click in the right hand window pane and select “Addconnection“ for all connected centrals. A maximum of 8 connectionscan be defined per Gx-CNET-LAN.

For each central the following definitions have to be made:■ In the field “IP Address of Destination Central“ the IP address of the

connected central has to be entered.■ In the field “Central blocks“ the block numbers of all centrals connec-

ted over this interface can be entered (a maximum of 8 block numbers, se-parate multiple entries by commas). Application see ”Network Functions”on page 24).

■ In the field „ID number subscriber“ it is possible to program a ID num-ber for each connected housing. The call numbers in the partner centralmust begin with this ID; in the own central housing the call numbers maynot begin with this ID. This prevents that at each dialling procedure a„Broadcast-message“ is sent to all housings connected via LAN.

Note: For the surveillance of the LAN-connection the Gx-CNET-LAN is regu-larly sending data (interval 4-8 sec) to the centrals in the network. This es-pecially is important, when centrals are connected via a non-permanentLAN-connection.

This tool (has to be set to “half duplex 10Mbit“) fullfills all requirements a IP network does fullfill: Each Gx-CNET-LANconnected to the switch is given a fixed and unique number. For a connection of centrals via this method, the IP addresses can be freelychosen.Anyway, it is recommended to use “Private IP addresses“, which are nottransferred in public networks.The switch has to be set to “Half duplex 10 Mbit“.

The following three blocks of the IP address space are reserved for privatenetworks:

10.0.0.0 to 10.255.255.255172.16.0.0 to 172.31.255.255192.168.0.0 to 192.168.255.255

Testing IP Addresses with PING G7-CNET-LAN / G2-CNET-LAN

Page 20 of 28 Vers. 2.0/0206

Testing IP Addresses with PINGFor diagnosis the Gx-CNET-LAN supports the PING protocol. With PING youcan check, if a Gx-CNET-LAN can be reached with its IP address. For thisdiagnosis you need a Windows PC in the same network as the Gx-CNET-LAN (e.g. connect the PC instead of one Gx-CNET-LAN, the PC must get thesame IP address - for assistance contact your network administrator).

Query the IP address of the PC■ Start a DOS window (search for “Command prompt“ in the Programs of

the Start menu, or select “Run“ in the Start menu and enter:%COMSPEC% or CMD)

■ Enter: IPCONFIG<Enter>■ Your own IP address and subnet mask is displayed. In addition e.g. a dial-

up adapter with IP address 0.0.0.0 can be displayed, this can be ignored.

■ Check, if your own IP address is in the same subnet as the IP address ofthe Gx-CNET-LAN.

Pinging the Gx-CNET-LAN■ Enter: PING and the IP address of the Gx-CNET-LAN, e.g.:

PING 192.168.170.125<Enter>The PC sends test data packets to the Gx-CNET-LAN. If the Gx-CNET-LANcan be reached, it sends an answer:

■ No packets may be lost and the displayed time may not exceed 100 ms, ifthe network is suitable for speech transmission. If the Gx-CNET-LANcannot be reached, a timeout is displayed:

If Ping is not working, this can also mean, that the Ping protocol isblocked by Routers or Firewalls.

Network FunctionsCentral blocks can be defined for functions like All Call, Group Call, etc. incentral networks (GEV 700, CNET-LAN, CNET-E1, CNET-W, S0). The centralblocks define, in which central housings these functions are initiated. Bypre-dialling a code number one central or a group of centrals are selectedand then the function is carried out. If no code number is pre-dialled thefunctions are carried out in all central housings connected overGEV 700, CNET-E1 or CNETW, but not in central housings connec-ted over CNET-LAN or S0.

These central blocks can be used for the following functions:■ All call, Group call■ Ringing at a group■ Alarm■ Music, Radio conference 6T■ Predefined conference 7T■ Subscriber index■ Chime signal■ Call request■ Video■ Central Control Desk, V24-Output (Comwin) - required only for CNET-LAN

or S0-networks

Define the block numbersThe block numbers may not collide with the calling numbers, input-or output numbers! If you want to use 1-digit block numbers for the central blocks, please mind,that most of the digits are reserved for functions:

That means, all digits except 1, 2 and 3 are reserved for the internalfunctions (the function codes could be changed - see manual “Features“,delivered with the centrals). Usually the calling numbers start with 1, 2 and3, so we recommend to use 2-digit block numbers (see ”Programming ex-ample” on page 26).

Program the Block Numbers

Block NumbersAt “General Settings“ in the folder “Central“ the block numbers for all cen-tral housings are entered. Several block numbers (a maximum of 6 per hou-sing) are entered in the fields “Configuration Block“ and “No. - Block 1“ to“No. - Block 5“.

Configuration BlocksIn a configuration block certain definitions can be made for all centrals inthis block (e.g. switch-off times, waiting signals, hierarchy levels etc.).

In standard all centrals are contained in “Configuration Block 0“. The set-tings for this configuration block can be found at “Central Block 00“.Attention: For an accessing of outputs, the configuration block must nothave the number “00“.

It is possible to define a separate configuration block for each central. Foreach defined configuration block an own folder is created in CCT:

Define the connectionsFor each Gx-CNET-LAN connection it it is possible to define, which centralblocks shall be reached via this interface.

Open the folder “Gx-CNET-LAN“ in the tree structure and click on one of thecentrals. In the field “Central blocks“ the block numbers of all centralsconnected over this interface are entered (a maximum of 8 code numbers,separate multiple entries by commas).

Programming example

In this example e.g. the All Calls are initiated as follows:■ An All Call in housing 1 is initiated with 8100.■ An All Call in housing 2 is initiated with 8200.■ An All Call in housing 3 is initiated with 8300.■ An All Call in all three housings is initiated with 8000.

If these codes are too long, you can change them with direct dialling (at“Subscriber“ - “Direct Dialling“ - “Central - Block“), e.g.:“100=8100, 200=8200, 300=8300, 900=8000“

Now the All Calls are initiated as follows:■ An All Call in housing 1 is initiated with 100.■ An All Call in housing 2 is initiated with 200.■ An All Call in housing 3 is initiated with 300.■ An All Call in all three housings is initiated with 900.

If no block numbers are defined or pre-dialled, the functions are carried outin all central housings connected over GEV 700, CNET-E1 or CNET-W, not inthe central housings connected over Gx-CNET-LAN or S0.

Special programming for the functions■ All Call, Group Call, Predefined conference 7T: No special pro-

gramming necessary, selection of central blocks with pre-dialling.

■ Ringing at a group: Programming of direct dialling for the door stationwith number of the central block, e.g.: “4=81983“ for ringing at group 3 incentral block 81 with button 4.

■ Alarm: Programming of direct dialling for the initiator with number of thecentral block, e.g.: “0=819T21“ for initiating the alarm at group 1 in centralblock 81 with button 0. Not required for the code for quitting of the alarm.

■ Music, Radio conference 6T: At the function “Feed-in - Music“ or“Feed-in - Radio conference“ (in the folder “Subscribers“) in the com-bo-box “Receiver“ the central block, that shall receive this music channel/radio channel, can be selected.

■ Subscriber index: At stations EE 711 or EE 811 a central block can bepre-dialled before displaying the subscriber index with A , e.g.: 82A . At “Subscriberlist EE711/EE811/EE880“ in the folder “Central“ in thecombo-box “Central - Block“ it can be selected, which subscriber index isdisplayed with A without pre-dialling.

■ Chime signal: At “Chime-signal“ in the folder “Inputs“ in the combo box“Central - Block“ it can be selected, which centrals shall receive the chimesignal.

■ Video: At the function “Video“ in the combo-box “Central Block“ the cen-tral block can be selected, that shall receive the camera texts at the startof the system.

■ Central Control Desk (required only for CNET-LAN and S0-networks):- To transfer call requests and input messages to a central control desk

over Gx-CNET-LAN a central block, that contains all centrals where acentral control desk is defined or where a call request/input messagecomes from (also transferred), has to be selected in the combo-box“Controldesk-system“ at “General“ in the folder “Central - Block No“.

- If Central Control Desk Call Transfer is used in an Gx-CNET-LAN net-work, it can be an advantage to define different central blocks for diffe-rent central housings at “Controldesk-system“.Example: 3 centrals (A, B and C, each with a central control desk) areconnected over Gx-CNET-LAN. The central control desks B and C shallbe able to transfer calls to central control desk A. No call requests aredefined between central B and C. Each time a call transfer from centralB to central A is activated, a short connection would be established alsoto central C. This can be avoided e.g. with the following configuration:

- Note: After a restart it takes some time until the central control desksare detected correctly. This means that call requests cannot be carriedout immediatly after a restart.

■ Comwin (required only for CNET-LAN and S0-networks):- If a central control desk has defined “RS 232-connection“ or “Output di-

alling to V24“ and also conversation messages from centrals, that areconnected over Gx-CNET-LAN, shall be put out, at “General“ in the fol-der “Central - Block No“ in the combo-box “COMWIN“ it has to be sel-ected, from which central block messages shall be put out. Messagesfor call requests and input messages are put out in any case.

- If several centrals with separate “RS 232-connection“ or “Output dial-ling to V24“ are connected over Gx-CNET-LAN, it can be necessary todefine different configuration blocks for the different central housingsat “COMWIN“.Example: two separated Comwin-PCs are connected to two centrals(“RS 232-connection“). Each Comwin-PC shall only receive the mes-sages from the own central.
