Airbridge BTS3606A CDMA Base Station
The temperature controller may be an air conditioner or a heat exchanger, which
can ensure the normal operation of the BTS in the following ambient-temperature
ranges:
--Air conditioner: –40°C to 55°C
--Heat exchanger: –40°C to 45°C

These interfaces connect to the transmission system that
connects to the BSC. Support IMA/UNI, cascading, and ATM over
Fractional ATM function.
When E1 is selected, 75W and 120W load interfaces are
available.
When T1 is selected, the 100W load interface is available.
One CCPM/CECM can provide two optical interfaces. When it is
necessary to connect the BTS3606A to the ODU3601C, up to
three levels of ODU3601Cs can be connected.
Connect to the satellite receiver and satellite synchronization
antenna to provide long- term stable clock signals.
Provide high-precision clock when the GPS/GLONASS clock
signals are unavailable.
Provide local maintenance path.
Output 10 MHz signals for test purpose.
Output PP2S signals for test purpose.
Respectively connect to A, B, C, and N lines.
Respectively connect to grounding cable, and to the auxiliary
equipment.
Connect to the –48V DC power supply that is used to charge the
batteries.
When three sectors are configured, each sector corresponds to
two DIN connectors, which can be used for both transmitting and
receiving.
Provided by the PMU.
