ODU
This is a standard N-type female connector, used to connect
the CMU to the ODU or IRFU transceiver via IF cable. The IF
cable carries the following multiplexed signals:
Power supply at –48 V dc
Transmit signal at 350 MHz
Receive signal at 140 MHz
RFU control and status signals
Do not connect or disconnect the IF cable when the –48
V supply is applied to the CMU.
Management
This is a 10baseT and 100baseT Ethernet port, used to
connect the CMU to the management network when ‘out-of-
band’ management is implemented. It is not used when ‘in-
band’ management is implemented. For more information on
the Ethernet interfaces see
on
For 1+1 Hot Standby protection, spare pins in the
management port provide the protection interface between
the two CMUs at one end of a link. For more information see
