2 Dual TRX Module (EXxA)The Dual TRX Module (EXxA) is a two-carrier TRX unit. The module

contains the common (2 carrier) baseband part and two separate RF partsfor two transceivers (transmitter and receiver chains) and space for two

optional Wideband Combiner Modules (Ewxx).

The Dual TRX Module is used as:

. a combined module with the Dual Duplexer Module (ERxA), 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 separately 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 Nokia

Flexi EDGE BTS supports:

. EXTA GSM800

. EXGA GSM900

In 2-way diversity case the signal comes from DTRX's other Rx main

connector and with 4-way diversity the signal comes from the diversity Rx

connector.

7 Dual TRX Module (EXxA) LEDindications

The Dual TRX Module (EXxA) has two tri-colour LEDs on the front panel toindicate the operational status of the module and all fault conditions during

operation.

Table 5. Dual TRX Module LED indications

Colour Explanation

Cycling colours The user has pressed the "Highlight" button on the

BTS Manager.

Red The O&M software of the module is not running, or

7606 alarm (TRX faulty) is active on both carriers.

Red, blinking 7606 alarm (TRX faulty) is active on one carrier, or

7607 alarm (TRX operation degraded) is active on one

or both carriers.

Yellow Both carriers in the TRX module are blocked/locked

from EM/BSC, or

Both carriers in the TRX module are shutdown from

BSC, but TRX module is still providing power and

control for an ERxA, or

Both carriers in the TRX module are shutdown fromBSC, but TRX module is powered following a reset of

ESMA or ESEA module, or

Both carriers in the TRX module have LAPD on

TRXSIG channel disconnected when the carriers state

is supervisory, or

One carrier is not in supervisory state but other carrier

is in supervisory state with LAPD on TRXSIG channel

disconnected.

Table 5. Dual TRX Module LED indications (cont.)

Colour Explanation

Yellow, blinking TRX_OM SW state is in TRX_Started State, or

TRX_OM SW state is Clock sync, or

One or both carriers are configuring:

. Wait for LAPD establishment

or

. Wait for system information

One or both carriers have LAPD on TRXSIG channel

disconnected when none of the carriers are in state

supervisory.

Green Both carriers are in state supervisory and no 7606 or

7607 alarms are active and LAPD on TRXSIG is

connected to both carriers.

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

7607 alarm is active and LAPD on TRXSIG is

connected for this carrier, or

Both carriers are in state supervisory but one carrier

has LAPD on TRXSIG channel disconnected.
