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.
For example 1: When STU-R E1 RX line is drop, 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.
For 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.
