9926 BBU introduction

Introduction

The 9926 BBU is designed to be connected to radio devices via optical fiber links.

It is factory-equipped with the following components:

• One eCCM-U module (slot 1)

• One eCEM-U module (slot 2)

• Two fillers (slot 3 and slot 4)

Depending on the capacity requirements, the 9926 BBU shelf can host two eCEM-U

modules in place of the two fillers (slot 3 and slot 4).

Optionally, the 9926 BBU can be equipped with the following components:

• One alarm module

• One Lighting Protection module (LPPCM or MLP)

Benefits

The Alcatel-Lucent Remote Radio solution improves flexibility for deploying mobile

broadband Node Bs in space-constrained locations. It is particularly suited to

macro-cellular applications in dense areas, where site acquisition is difficult, and on sites

where installation constraints prevent the use of legacy Node Bs.

Compared to legacy Node B site deployment, the Remote Radio solution provides the

following benefits:

• Reduced volume, weight, footprint, acoustic noise, and power consumption

• Reduced cost of feeder paths from the Node B to the antenna

• Increased RF power per carrier at the antenna feeder

• Reduced radio loss with use of the remote RF block concept, which eliminates the

distance between the radio amplifier and the antenna

The Remote Radio solution provides for the UMTS system:

• The means of communication between a User Equipment (UE) and a network using

Transport Channels

• Physical layer channels, which are necessary to synchronize the downlink and

perform cell selection/reselection and handover preparation

• Measurement information to the RNC for radio resource management (handover,

power control)

The 9926 BBU provides up to eight E1/T1 with Inversion Multiplexing ATM (IMA) or

Drop-and-Insert capability (fractional E1/T1). The 9926 BBU also supports multi-PCM

without IMA.

The 9926 BBU delivers high UMTS radio performances and supports the enhanced High

Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access

(HSUPA) solutions through easy software upgrade.

The 9926 BBU is compliant with the Common Public Radio Interface (CPRI).

9926 BBU enclosure

The 9926 BBU provides the operators with a suited solution whatever the site constraints.

The 9926 BBU can be integrated:

• In a standalone indoor mode or in an existing indoor or outdoor Alcatel-Lucent 9100

Multi-Standard Base Station cabinet for multi-standard configuration

• In a small or a medium Power Supply Unit (PSU) outdoor cabinet

• In a 2G S8000 or S18000 Oudoor BTS cabinet

9926 BBU features and functions

Introduction

The 9926 BBU supports the following functions:

• Call processing

• Performance monitoring

• Network interface

• Configuration/supervision

• Synchronization

Call Processing (CallP)

The call processing function is in charge of the radio resource management inside the

Node B. This function manages the UMTS services (described in 3GPP standards) and

the internal services used for configuration and implementation purposes.

The call processing function is also in charge of:

• Common channel management, which includes setup, release, and modification

procedures

• Dedicated channel management, which includes setup, release, and modification

procedures

• Cell management, which includes setup, deletion, and modification of a cell

• Power control for controlling UE power emission

• Softer handover, in which a single Node B manages the cells in communication with

the UE

• Common Channels defense in case of CE (Channel Element) failure by relocating

them autonomously to the available CE resources (same board or another) without

involvement of the RNC.

Call processing is mapped on the eCCM-U and eCEM-U.

The Node B call processing supports the multiple eCEM-U. The multiple eCEM-U (or

multi-eCEM-U) enables to use several eCEM-U for call processing management.

Performance monitoring

The performance monitoring function is in charge of collecting performance

measurement data from the network interface function and from the

configuration/supervision function.

The measurement data is used to calculate and report performance data to the RNC for

traffic control and to the WMS for network operation and tuning.

PCM (Drop-and-Insert capability), and redundancy management.

• Ethernet links

From LR13.1, 9926 BBU can be daisy-chained on the same Gigabit Ethernet backhaul

connection. For this it is necessary to use the eCCM-U-GE (with the GE MDA) using the

fiber optic SFP or built-in RJ45 ports.

Configuration/supervision

This function is in charge of:

• Module configuration and supervision

• Inventory information reporting

• Plug-and-play management

The remote inventory functionality provides the UMTS OAM access to determine the

inventory information of the Node B. The remote inventory is performed for the

following modules: eCEM-U, eCCM-U, fan tray and optional modules (alarm module,

lightning protection module).

Synchronization

This function is in charge of retrieving highly stable radio frequency from either network

interface or optional GPS receiver.

The 9926 BBU can be synchronized through the following means:

• E1/T1 PCM link (standard synchronization mechanism)

The E1/T1 link used for synchronization does not carry any data traffic.

• External GPS receiver

In the GPS-based synchronization solution, the eCCM-U module is connected to a

GPS smart antenna/receiver that provides GPS synchronization source (Pulse Per

Second (PPS) synchro input from the antenna).

• Integrated GPS receiver

Note: This synchronization mechanism is optionally available with the eCCM-U

module.

• IEEE 1588v2 Precision Time Protocol (PTP)

The PTP-based synchronization solution relies on time servers connected to the 9926

BBU through the Ethernet network.

Note: This synchronization mechanism only applies to native IP Node B .

• Synchronous Ethernet

9926 BBU external interfaces

Introduction

The 9926 BBU is equipped with four main types of external interface:

• E1/T1 and/or IP network interface (Iub)

• Optical interface to radio devices

• Alarm/remote control interface (optional)

• Power supply interface (DC input)

Interface location

The following diagrams show the locations of the interfaces on the 9926 BBU.

The GE MDA provides three GE ports: two are optical using SFPs, the third is an

electrical GE interface. The SFP2 and electrical interface are, however, the same logical

port and so only one can be used.

The E1/T1 MDA provides four E1/T1 PCM Iub ports. Added to the four E1/T1 ports on

the eCCM-U card, this provides a total of eight E1/T1 PCM ports.

Network interface

The network interface Iub of the 9926 BBU can be either ATM based, hybrid or IP.

ATM-based Iub interface

The ATM-based Iub interface consists of eight E1 or T1 PCM links:

• E1 link complies with ITU G703/G704

• T1 link is based on the ANSI standard

The raw data rate between Node B and RNC can rise up to 15.872 Mbit/s (E1) or 12.288

Mbps (T1). Depending on the data flow, ATM AAL2 and AAL5 are used on the above

physical link through IMA. The IMA framing provides for physical link performance

monitoring and management.

In the case of a 120-ohm network, the only equipment needed to ensure the PCM

connection is the 120-ohm PCM cable.

In the case of a 75-ohm network, it is necessary to have baluns (two baluns per PCM) to

ensure adaptation from the 120 ohm of the Node B to the 75 ohm of the customer

network. Four types of baluns can be used: BNC, 1.6/5.6, SMZ type 43, or BNC to RJ-45.

Hybrid Iub interface

The Hybrid Iub interface consists of:

• ATM/PCM connectivity for R99, HSDPA, or HSUPA signaling and OAM traffic

• IP/Ethernet connectivity for HSPA traffic (HSDPA + HSUPA, or HSDPA only)

The Hybrid Iub interface requires the eCCM-U module in “eCCM-U-E1-4PCM” or

“eCCM-U-GE” hardware configuration.

The Hybrid Iub can use one of these options:

• Optical GE via one SFP GE port of the GE MDA

• Electrical GE via the RJ45 connector on the GE MDA

• FE via Port 2 of the eCCM-U

The native IP Iub interface requires the “eCCM-U-GE” hardware configuration.

Native IP Iub interface

The native IP Iub interface consists of a full IP/Ethernet transport on Iub interface. When

native IP Iub feature is deployed, the ATM/PCM connectivity is no longer used for the

Iub.

BTS daisy-chaining

From LR13.1, BTS daisy-chaining allows one GE link to serve a number of

Alcatel-Lucent base stations. The base stations can be multi-generation of 2G, 3G or 4G.

The number of base stations is limited to 1 Gb/s of the GE link, or by the capacity of the

switch in the most upstream base station of the chain.

When a base station A is located upstream in the daisy chain with respect to the position

of another base station B, it is called a ‘Chaining BTS’ or a ‘Dropping BTS’. BTS B is

called a ‘Chained BTS’ or a ‘Dropped BTS’.

In this system release the validated configurations are

• 3G chaining to 3G chained

• 3G chaining to 4G chained using IPV4

• 3G chaining to 4G chained using IPV6

• 3G chaining to 4G chained using IPV4 with IPSEC

A 9926 BBU can be used for daisy chaining once the software is upgraded in the 9926

BBU. The feature can be activated without the need to reset the dropping Node B to

activate the feature.

BTS daisy-chaining uses only the GE ports on the GE MDA on the eCCM-U-GE. Fiber

port SFP2 and the RJ45 port are internally connected and so cannot be use

simultaneously, so one of these ports is used in conjunction with the SFP1 fiber port.

The BTS daisy-chaining also carries time/clock synchronization using Synchronous

Ethernet protocol or IEEE 1588v2. The synchronization data may be generated by the

backhaul. Alternatively, any Node B in the chain can be configured to get synchronization

from an external synchronization source and propagate the synchronization data

downstream only via the daisy-chain. Note that only fiber SFPs and the RJ45 port can

propagate SyncE: copper SFPs do not support this feature.

enhanced Channel Element Module-U (eCEM-U)

Main functions

The eCEM-U performs the same function as the xCEM-U.

However, it embarks hardware improvements that support the higher capacity required

for MIMO and HSPA+ features.

The eCEM-U performs the baseband radio signal processing and part of the call

processing.

The eCEM-U supports up to:

• 256 UMTS voice channels

• 128 HSPA channels

The eCEM-U performs both uplink and downlink traffic processing with both Rx and Tx

diversity with no capacity loss.

The processing function includes the following:

• Rx signal processing (de-correlation, finger processing, MRC, search,

de-multiplexing, de-interleaving and decoding)

• Tx signal processing (coding interleaving, channel multiplexing, spreading, summing

and power weighting)

The eCEM-U supports the softer handover feature across up to six sectors.

The eCEM-U also manages the traffic network interface for ATM termination and data

scheduling for the HSDPA/E-DCH support.

The eCEM-U handles call processing functions along with OAM operations.

Hardware description

The eCEM-U is composed of:

• One main board (size 389.6mm x 274.8mm)

• One front panel

All the eCEM-U interfaces are located at the rear of the module and connected to the

RBP. The front panel only includes LEDs and debug interfaces.

The following figure shows the eCEM-U front panel.

75-ohm kit

Description

The PCM cables are connected to the customer DDF. This distribution frame is a

connection point between the PCM cable from the Node B and the transmission network.

For a 120-ohm telecommunication network, only the 120-ohm PCM cable is needed for

PCM connection.

For a 75-ohm telecommunication network, it is necessary to have baluns (two per PCM)

to ensure adaptation from the 120 ohm of the Node B to the 75 ohm of the customer

network. The 120/75 ohm adaptation baluns should be secured as close as possible to the

specific distribution frame. Four types of baluns can be used: BNC, 1.6/5.6, SMZ type 43,

or BNC to RJ-45.

The following figure shows the four types of baluns available.

Introduction

The Local Installation Terminal (TIL) is an O&M onsite terminal. The TIL is used for the

installation, tests, and maintenance of the equipment described in this document.

TIL functions

The TIL provides the following functions:

• Displays the existing hardware of the equipment

• Automatically displays new hardware

• Basic maintenance and test capabilities for equipment modules

• Saves reports (including alarm, test reports) on a laptop

• Retrieves the hardware and software module configuration

• Configures commissioning parameters

TIL connection to the equipment

The TIL is connected to the CCM module through the Ethernet connection.

Two connection modes are available from the TIL:

• Peer-to-peer connection

In this mode, the TIL connection to the equipment depends on the CCM module type,

as described in the following table:

If the CCM module hosted in the

equipment is a...

Then the TIL is connected to the...

CCM/iCCM/iCCM-U/iCCM-2 Ethernet port 2 of the CCM module

xCCM/xCCM-U/eCCM-U Ethernet port 1 of the CCM module

• Remote connection

In this mode, the TIL is connected to a LAN/WAN network. This connection is

available only if the equipment is integrated in the UMTS network and active (not

locked).

The connection can be checked by doing a ping [IP address] command.

For more information, see Alcatel-Lucent 9100 and 93xx Node B – Commissioning and

Fault Management User Manual: TIL, NN-20500-019.
