MCPA TBS SYSTEM USER MANUAL
1.1 PURPOSE OF MCPA TBS SYSTEM
BTS coverage extension and network optimization
The system is designed to enhance the downlink output power to a high power and make up
for the cable loss between antenna and BTS. Working together with Tower Mounted Amplifier
(TMA) at the top of tower which can improve the BTS receiver sensitivity, the whole system
can provide more balance both for uplink and downlink budget. So the system can help
network optimization and improve network KPI.
CAPEX cutting and flexible for traffic capacity expansion
With integrated high power MCPA module, wireless operators can combine downlink signals
together without worrying about the power loss and coverage are shrinking. This can help
wireless operators decrease the investment of feeder lines and antennas dramatically.
Meanwhile, our customers can do traffic capacity easily and don’t concern the number of
carriers, spacing of carriers and the intermodulation interference which is caused in SCPA
system.
OPEX cutting and easy for maintenance
Deploying MCPA technology, it can help decrease the number and the power of active
modules in BTS system so that it can improve the MTBF. And compared to the efficiency of
using SCPA, the system can improve the overall BTS system efficiency with lower power
consumption. The features will help customer cut their operation expense.

2.3 POWER SUPPLY REQUIREMENT
The power cable selection should rely on the distance between rectifier and Backplane. At the
power terminal of Backplane for MCPA and Cooling Fans, a 27+/-1Vdc is needed.
The AC or DC power source must be connected to dedicated lightning
arrestor to avoid damage to TBS system in case of lightning.
CAUTION
All modules of TBS system should be well grounded.
2.3.1 UNPACKING AND INSPECTION
TBS system was factory tested, inspected, packed, and delivered to the carrier with utmost
care. When the equipment is delivered to installation site, go through the following unpacking
and inspection process.
1: Carefully unpack and check each package/container against the packing list. For any
shortage, double confirm with carrier. Do not remove items from packing materials until
installation.
2: Visually inspect the enclosure, connectors, and cables for damage caused by improper
shipment. Try to check whether there is evidence for water leakage, bent or wrapped chassis,
loose screws or nuts, or extraneous packing material in the connectors or fans. Inspect male
connectors on modules and harnesses for bent connector pins.
Note:
1. If the equipment is damaged or something is missing, do not accept shipment
from carrier until the carrier's agent endorses a statement of the irregularity on the
face of the carrier's receipt. Without documentary evidence, a claim cannot be
processed.
2. After confirm with carrier and delivery person, if the equipment needs to be
returned to factory, contact with Comba local office (see Appendix B) to get a return
authorization and go through RMA process (Refer to Appendix C)

3.2 SYSTEM DC POWER ON AND OFF PROCEDURES
The following procedures are for TBS system DC power on and off.
1. Test the antenna system and ensure the echo loss within working frequency is less than
-14dB (VSWR<1.5).
Do not turn on the power supply from Rectifier.
Do not turn on input power from BTS.
DANGER
2. Visually inspect the power connection within the equipment. Ensure that the power cable is
correctly and securely connected.
3. Check grounding connection and verify that the ground resistance is less than 5Ω.
4. Check all circuit breaker of MCPA modules have been set to OFF. And Enable Switch has
been set to DISABLE position.
5. Before turn on MCPA Module, use power meter to test the input composite power from BTS
is not more than 43dBm.
Do not input >43dBm power into MCPA.
Before applying power from BTS, please make sure the MCPA has been
WARNING
properly terminated at 50 ohms.
6. Turn on the power from Rectifier and verify the input voltage for MCPA is in the range of
26-28Vdc on the power terminals at the back of Backplane. After power on, the cooling fans
will run and LED indicators on System Controller front panel will become stable without red or
amber color.
7. Turn on power of MCPA one by one (set Circuit Breaker to ON and push Enable Switch to
ENABLE). Check the LED indicators and there’s not red or amber color.
Note:
After this step, all LED indicator status on the front panel of System Controller and
MCPA modules are in normal color (refer to table 21 & 22). If there are any alarms,
please contact with field engineer.
8. Push Enable Switch to DISABLE and push Circuit Breaker to OFF. Turn off power supply to
MCPA and rectifier. Write down installation record and check with field engineer for system
commissioning.
