In general, the Alarm relay state will reflect the state of the Front Panel LEDs. For instance,
if the Unit Status LED is red, the Unit Alarm relay will be active, etc. The one exception is
the Transmit Traffic relay. This will only be activated if a Transmit Traffic Fault exists – it
does not reflect the state of the TX carrier.
IMPORTANT
A Unit Fault exists (Example: PSU fault)
No Unit Faults, but a Traffic Fault, or ODU (BUC or LNB) fault exists
No Unit Faults, or Traffic Faults
No Tx Traffic Faults
A Tx Traffic fault exists OR the Tx Carrier is in OFF state
No Rx Traffic Faults (demod and Viterbi decoder are locked, everything is
OK)
An Rx Traffic fault exists (the demod may still be OK – check the fault
status of the unit from the Monitor menu).
The Unit is On Line, and carrying traffic
The Unit is Off Line (standby) - forced by externally connected 1:1 or 1:N
redundancy system
There is a Stored Event in the log, which can be viewed from the front
panel, or retrieved via the remote control interface
There are no Stored Events
The Unit is in Remote Mode - local monitoring is possible, but no local
control
The Unit is in Local Mode - remote monitoring is possible, but no remote
control
ODU FSK control has been enabled, and there is a communications fault.
Framing on, EDMAC on, and unit defined as Slave - local monitoring is
possible, but no local control
Either the unit is in Transparent mode (no framing), or the framing has
been selected, but in AUPC-only mode, or EDMAC Master configuration.
A Test Mode is selected (Example: IF Loopback)
There is no Test Mode currently selected
