Dual TRX Module (EXxx)

2 Dual TRX Module (EXxx)The Dual TRX Module (EXxx) is a two-carrier TRX unit. The module contains the

common (2 carrier) baseband part and two separate RF parts for two transceivers

(transmitter and receiver chains) and space for two optional Wideband Combiner

Modules (Ewxx).

The Dual TRX Module (EXxB) hardware can simultaneously support the following future

BSS features:

Full Voice services over Adaptive Multi-user Orthogonal Sub channels (VAMOS)

Enhanced General Packet Radio Service Evolution (EGPRS2)

The Dual TRX Module (EXxx) is used as:

a combined module with the Dual Duplexer Module (ERxx), making a logical Sector

Module

or a stand-alone TRX module with the Remote Tune Combiner (ECxA) Module or a stand-alone extension TRX module.

The Dual TRX Module and System Module (ESMA) communication is managed through

a single Ethernet interface. Each transceiver within the Dual TRX Module can be sepa-

rately activated with a licence key at the BSC.

The Dual TRX Module contains two transceivers that can be used:

as a separate TRX in the same sector

as a separate TRX in different sectors

or as a Double Power TRX.

or as an Intelligent Downlink Diversity (IDD) TRX.

There are separate Dual TRX Modules for each frequency band that Flexi EDGE BTSsupports:

EXTx GSM800

EXGx GSM900

EXDx GSM1800

EXPx GSM1900

See the following figure for an isometric view of the Dual TRX Module.

operational status of the module and all fault conditions during operation.

Colour Explanation

Cycling colours BTS has requested highlighting for TRX module and

timer is still running.

Red, blinking 7606 alarm is active on one of the carriers or

7607 alarm is active on one or on both carriers.

Red, stable TRX_OM SW is not running or

7606 alarm is active on both carriers.

7606 alarm on IDD TRX or DPTRX TRX object.

Yellow, blinking TRX_OM SW state is Clock sync or

one or both carriers are in TRX_OM SW state TRX con-

figuring, Wait for OMUSIG establishment or Wait for

system information.

Yellow, stable Both carriers are blocked from BTS or

both carriers have TRXSIG channel disconnected when

in TRX_OM SW state is supervisory.

IDD TRX or DPTRX object blocked/locked or IDD TRX or

DPTRX TRX object is Shutdown (but is still providing

power/control for DDU supporting other TRX's or are

powered due to malfunctioning e.g. power cycle in

ESEA) from BSC or

IDD TRX or DPTRX TRX object has TRXSIG channel

disconnected when the carrier state is supervisory.

Green, blinking Only one carrier is in the supervisory state and no 7606

or 7607 alarm is active and LAPD on TRXSIG is con-

nected for this carrier, or.

both carriers are in supervisory state but one carrier has

LAPD on TRXSIG channel disconnected.

Not applicable when the TRX module is configured for

IDD TRX or DPTRX TRX object.

Green, stable Both carriers are in TRX_OM SW state supervisory and

no 7607 or 7606 alarms are active.IDD TRX or DPTRX TRX object is in supervisory state

and no 7606 / 7607 alarms are active and TRXSIG is

connected.
