AIS/ALM
The AIS/ALM (Alarm Indication Signal/Alarm) setting allows you to specify the type of
“keep-alive” signal the system will generate on one T1/E1 link if the other one fails. The
AIS/ALM setting depends on the Frame Format selected for this WAN card. Table 7-6 shows
the AIS/ALM settings for cross-connect systems.
