Configuring the AIS Delay
An alarm indication signal (AIS) is sent to CPE at each end of a connection when the switch detects a
connection alarm. The derouting of a connection triggers the AIS signal, and depending on the CPE
configuration, the derouting may trigger a switchover of the CPE to backup facilities. The AIS delay
timer feature is designed to delay a locally generated AIS event long enough that a new connection can
be established during grooming. If the new connection is established before the end of the AIS delay, no
AIS is generated.
Note
The AIS delay does not affect AIS signals generated on other switches and forwarded to this switch.
