The display presents the following information:
•
Signal Loss:
Whether Access-T is receiving a valid signal from the T1
line. (Loss of Signal is declared if Access-T receives 175
±
75 consecu-
tive ZEROS.)
•
Sync Loss:
Whether Access-T has lost framing synchronization on
the signal received from the T1 line.
•
USS:
Whether an Unavailable Signal State exists.

Rcv Yellow:
Whether Access-T is receiving Yellow Signal from the T1
line. If so, the far-end CSU has lost sync on the signal from the line.
•
Rcv AIS:
Whether Access-T is receiving Alarm Indication Signal
(AIS), an unframed All ONES signal.
•
Master Clk Loss:
Whether Access-T is receiving a valid master clock
signal. If the Access-T loses its master clock, it will use its own internal clock
until the selected master clock is regained. (If the Aux port is serving as
the master clock and clock source is lost, Access-T will not register
Master Clock Loss; however, it will fall back on its internal clock.)
•
Port1 RTS Loss:
Whether the RTS input to DTE Port 1 is present.
•
Port2 RTS Loss:
Whether the RTS input to DTE Port 2 is present.
•

the T1 input to the auxiliary (drop-and-insert) port.
