Setup E1 Parameter, AIS

AIS (Alarm Indication Signal) is a method to inform the remote connection that there is a signal or sync problem with the E1.

AIS is only valid in framed mode E1, not in Unframed E1. The setting here of AIS enabled (on) or not (off) and is for testing with

AIS. When enabled, the E1 will transmit the AIS and it should be confirmed at the remote device (AIS indication lit). After testing,

please turn AIS back off.

z Example 1: When STU-R E1 RX line is dropped, STU-R sends the status to STU-C via EOC or command, and then

STU-C will send AIS (Alarm Indication Signal) to DTE while AIS function is enabled.

z Example 2: When SHDSL connection drops, STU-R and STU-C both send AIS (Alarm Indication Signal) to DTE in the

same time while AIS function is enabled.
