x
Power supply –48 V dc
x
Transmit signal at 350 MHz
x
Receive signal at 140 MHz

ODU control and status signals
CAUTION
Management port
The PTP 800 system supports network management communications in two modes:
"out-of-band" and "in-band". In the "out-of-band" mode, the system is managed by
connecting to the CMU through the management port.
The management port supports 10baseT and 100baseT Ethernet.
For more information on the Ethernet interfaces see
36.
Recovery switch
The recovery switch is used to start the CMU in recovery mode. Recovery mode
provides a means to recover from serious configuration errors including lost or
forgotten passwords and unknown IP addresses. For more information see
Recovery mode
Recovery mode also allows new main application software to be loaded even when
the integrity of the existing main application software has been compromised.
Copper data port
The copper data port connects the customer traffic network.
In the "in-band" management mode, the system is managed through the data port,
and management traffic is multiplexed with customer traffic.
The copper data port supports 100baseT or 1000baseT Ethernet.
For more information on the Ethernet interfaces see
