DTE Alarm Indication Signal (AIS)
DTE AIS is declared when Radio Sync Loss (RSL) is detected, or when there is
an active loop test that does not involve this DTE connection. The AirLink Pro
T1/E1 Rack Mount sends an unframed, all-ones signal toward the DTE. This
condition is cleared after RSL ceases or the loop test is terminated. For more
information on AIS conditions, refer to “Carrier Failure Alarms” in “Acquiring
Alarm Information”, later in this chapter.
RF Alarm Indication Signal (AIS)
RF AIS is declared when LOS is detected, or when there is an active loop test
that does not involve this connection. The AirLink Pro T1/E1 Rack Mount sends
an unframed, all-ones signal toward the remote AirLink Pro T1/E1 Rack Mount,
which passes it on to the remote DTE. This condition is cleared after LOS ceases
or the loop test is terminated. For more information on AIS conditions, refer to
“Carrier Failure Alarms” in “Acquiring Alarm Information” in this chapter.
