Remote Loop Test, Far End
The Remote Loop test, Far End (Figure 4-11) causes the over-the-air received
T1/E1 signal to be looped back at the output of the receive T1/E1 signal
processing circuits. This loopback includes all of the radio circuits and
approximately 90% of the digital circuits. The affected AirLink Pro T1/E1
Rack Mount sends an unframed, all-ones Alarm Indication Signal (AIS) toward
the DTE.
