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.
