1.2 Description of SNs of MTMA
The SN of a MTMA contains 17 digits:
The first two digits indicate the manufacturer code, fixed as HW.
The third and fourth digit indicate the Marking code.
The fifth to eighth digits indicate Tx band features.
Obtain the lower band edge frequency of the Tx band. For example, if the Tx band is
1805 MHz to 1880 MHz, the lower band edge is 1805 MHz.
The ninth and tenth digits are obtained at random.
The eleventh and twelfth digits indicate the ex-factory year.
For example, take 04 for the year of 2004; take 10 for the year of 2010.
The thirteenth digit indicates the ex-factory month.
The value is a hexadecimal digit. For example, take 1 for January, and A for October.
The fourteenth to seventeenth digits are obtained at random.

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

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.
Step 2 In the related parameter input area, specify related parameters.
The parameter values in the following figure are only for reference.
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.
Step 3 Press F9 or click .
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.

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.
Step 2 In the related parameter input area, specify related parameters.
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
LTE BTS (R05) Configuration Guide 2 Typical Description

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

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.
Step 1 Press F9 or click .
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

Step 2 In the related parameter input area, specify related parameters.
The parameter values in the following figure are only for reference.
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.
Step 3 Press F9 or click .
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.
