Installation Manual – BTS3606 Cabinet Installation
Airbridge BTS3606&3606A CDMA Base Station
4.2.1 Installing GPS/GLONASS Clock RF Cables
Note:
The BTS3606 is configured with two black flexible RF cables. One end of the RF
cable is connected to the GPS/GLONASS feeder interface on top of the cabinet, and
the other end is placed in the cable trough of the baseband subrack upon delivery
and is to be connected to the front panel of BCKM in the baseband subrack during
cable installation.
To install GPS/GLONASS clock RF cables, proceed as follows:
1)
Check that the feeder is connected to the GPS connector on the top of the
cabinet.
2)
Select a cable marked with GPS_0.
3)
Connect the cable to the ANT connector of the BCKM front panel.
If the BTS3606 is configured with two BCKM boards, each board must be configured
with a set of GPS/GLONASS synchronization antenna feeder. In this case, connect
cables to the ANT connectors on the BCKM front panel according to cables labels.
4.2.2 Installing RF Cables Between CDDU/CHPA/CTRM (Single-Channel)
The connection of RF cables varies with the configurations of RF modules. Table 4-3
