Facility - the received signal is looped back towards the transmitter port
immediately on entering the interface port. AIS is inserted in the signal
towards the cross-connect on the 2x155/622M aggregate circuit pack.
Terminal - the signal is looped back towards the cross-connect on the
2x155/622M aggregate circuit pack just before reaching the interface
transmitter.
