Notice:Notice:
BCKMBCKM
When GPS, GLONASS or external synchronous
1PPS Signals are activated, the clock is in the
normal running mode.
When GPS, GLONASS or external synchronous
1PPS fails, the local clock is in the holdover mode.
Under this state the system can run normally for
more than 8 hours.
![Page 18: cBts3606-Hardware-System](https://reader036.vdocument.in/reader036/viewer/2022081404/5572135e497959fc0b922aa8/html5/thumbnails/18.jpg)
Active/Standby RunningActive/Standby Running
BCKMBCKM
When fault occurs in the active BCKM, then the
services will switch over to the standby BCKM under the
control of the related software or automatically. In
following three cases this switching is occurred:
A. Abnormality in CLK leads to BCKM switchover.
B. Abnormality in MPU leads to BCKM switchover.
C. The hardware failure and damage of important devices of
the board lead to BCKM switchover.

CTRM’s FunctionsCTRM’s Functions
•In the reverse link, the CTRM receives the main and diversity RF
signals from the antenna and feeder subsystem, and then changes
them into baseband signals through down conversion, wave filtering
and multiplexing. Finally the CTRM sends the baseband signals to the
baseband subsystem.
•In the forward link, the CTRM receives the baseband signals from the
baseband subsystem, and then changes them into RF signals through
de-multiplexing, wave filtering and up conversion. Finally the CTRM
sends the RF signals to the RF subsystem through the CDDU.
•Supported band: 450 MHz, 800 MHz, and 1900 MHz
