6. If RRUs are used on a TMA, the power supply switch of the RET port on the RRU must be turned

off when you turn on the power supply switch. Otherwise, the power supply switch of the R0A

port cannot be switched on. For details about how to turn off the power supply switch of the RET

port, see A.1.9 Turning Off the Power switch of the RRU RET Port.

7. Unless otherwise stated, parameters in red are mandatory.

Step 3 Press F9 or click .

If Execution succeeded is displayed in the command export area, the TMA power switch is

turned on successfully. If the switch fails to be turned on, identify causes and reset the power

switch.

2.2 Querying the Actual TMA Current

You can run DSP ANTTENNAPORT to query the actual TMA current and check whether

the TMA runs properly based on the reference currents in the TMA datasheet.

Procedure

Step 1 In the parameter input area, enter DSP ANTTENNAPORT in Command Input(F5), and


Step 2 In the related parameter input area, specify related parameters.


Cabinet No., Subrack No., Slot No., and Port No. are optional. If they are left empty, the ALD current

of all TMAs in the entire BTS will be queried.


If Execution succeeded is displayed in the command export area, the actual current is queried

successfully. If the actual current fails to be queried, identify causes and query the actual

current again.

NOTE

TMA

2.3 Scanning TMAs

You can run SCN ALD to scan TMAs in the system.

Procedure

Step 1 In the parameter input area, enter SCN ALD in Command Input(F5), and then click

or press Enter.



Control port cabinet No., Control port subrack No. and Control port slot No. are optional. If they

are left empty, will scan all TMAs in the entire BTS.


The scanning progress and result are displayed in the parameter input area. The progress

depends on the number of equipment connected. If Execution succeeded is displayed in the

command export area, the TMA is scanned successfully. If the TMA fails to be scanned,

identify related causes and scan the TMA again.

The returned result varies based on the AISG versions.

AISG 1.1

Use the MTMA for an example, the following figure shows the information obtained

after scanning the MTMA.

1. An MTMA has 4 serial numbers.

2. An DTMA has 2 serial numbers.

AISG 2.0

Use the MTMA for an example, the following figure shows the information obtained

after scanning the MTMA.

NOTE

TMA




7

1. An MTMA has 2 serial numbers.

2. An DTMA has 1 serial number.

Step 4 Verify the number of TMAs and SNs of these TMAs.

1. MTMAs are classified into two-port-input two- port-output MTMA, and two-port-input four-port-

output MTMA based on the port quantity.

The two-port-input two- port-output MTMA is applicable only to single-BTS control

scenarios. That is, only one BTS can send commands (OOK signals) to the MTMA for

configuration and maintenance.

The t two-port-input four-port-output MTMA is applicable to dual-BTS control scenarios.

That is, two BTSs can send commands to the MTMA.

2. In dual-BTS control scenarios, both BTSs can execute the scan command.

When no serial number of two-port-input four-port-output MTMA is configured, both BTSs

can execute the scan command to scan all serial numbers of the MTMA.

When some of serial numbers of two-port-input four-port-output MTMA are configured on a

BTS, the other BTS can scan only the remaining serial numbers of the MTMA.

For example, the two-port-input four-port-output MTMA supporting the AISG 2.0 protocol has

two serial numbers HWD1 and HWD2. When the MTMA is not configured, both BTSs can scan

HWD1 and HWD2. When HWD1 of the MTMA is configured on a BTS, the other BTS can scan

only HWD2.

2.4 Adding a TMA You can run ADD TMA to add a TMA.

Procedure

Step 1 In the parameter input area, enter ADD TMA in Command Input(F5), and then click

or press Enter.


The parameters are configured differently based on the AISG versions. Use the MTMA for an

example.

AISG 1.1

The MTMA has four serial numbers, and therefore the BTS needs to execute four adding

commands to add all serial numbers.

TMA




8

The DTMA has two serial numbers, and therefore the BTS needs to execute two adding

commands to add all serial numbers.

When the two-port-input four-port-output MTMA is applicable to dual-BTS control

scenarios, each BTS needs to run two adding commands to add all four serial numbers.

The two serial numbers added on a BTS must contain the same frequency band

information, and the frequency band information must be consistent with that of the BTS.

For example, when the following four serial numbers are scanned: HWD1 (frequency

band: 1805 MHz), HWD2 (frequency band: 1805 MHz), HWD3 (frequency band: 2110

MHz), and HWD4 (frequency band: 2110 MHz), only the serial numbers HWD1 and

HWD2 can be added on the GSM1800 BTS, and the serial numbers HWD3 and HWD4

are added on the UMTS2100 BTS.

1. Device Name is user-defined and unique.

2. Control Port Cabinet No., Control Port Subrack No. and Control Port Slot No. are configured

as required.

3. TMA Subunit Number is 1.

4. Vendor Code and Serial No. are in the scanning result.

AISG 2.0

The MTMA has two serial numbers, and therefore the BTS needs to execute two device

adding commands to add all serial numbers.

TMA




9

The DTMA has one serial number, and therefore the BTS needs to execute one device

adding command to add all serial number.

When the two-port-input four-port-output MTMA is applicable to dual-BTS control

scenarios, each BTS needs to run one adding command to add all two serial numbers.

The serial number added on a BTS must have the same frequency information with the

BTS’.

For example, when the following two serial numbers are scanned: HWD1 (frequency

band: 1805 MHz), HWD2 (frequency band: 1805 MHz), only the serial number HWD1

can be added on the GSM1800 BTS, and the serial number HWD2 is added on the

UMTS2100 BTS.

1. Device Name is user-defined and unique.

2. Control Port Cabinet No., Control Port Subrack No. and Control Port slot No. are configured

as required.

3. TMA Subunit Number is 2.

4. Vendor Code and Serial No. are in the scanning result.


If Execution succeeded is displayed in the command export area, a TMA is added

successfully. If the TMA fails to be added, identify causes and add the TMA again.

2.5 Setting an Attenuation Factor for the Receiving Channel

You can run MOD RXBRANCH to set an attenuation factor for the receiving channel of a

specified RFU or RRU when the RFU or RRU connects to a TMA.

Procedure

Step 1 In the parameter input area, enter MOD RXBRANCH in Command Input(F5), and then

click or press Enter.

TMA




10



1. Cabinet No., Subrack No. and Slot No. are configured as required.

2. The receiving channel 0 corresponds to R0A and receiving channel 1 corresponds to 1. The

attenuation of R0A and R0B must be configured. Therefore run MOD RXBRANCH twice and

choose 0 and 1 separately.

3. Logical switch of Rx channel is set to ON.

4. The attenuation factor of the receiving channel equals the actual tower amplification gain minus

cable losses. The actual tower amplification gain can be queried by running DSP TMASUBUNIT.

The cable loss is calculated based on the actual length of cables used at the site, including jumpers,

feeders, and connectors.


If Execution succeeded is displayed in the command export area, the attenuation factor is

configured successfully. If the attenuation factor fails to be configured, identify causes and

reset attenuation factor.
