AIS to DTE
When at least one DS0 is assigned to the auxiliary port and you want Access-T
to generate AIS toward the aux port,
AIS TO DTE
must be enabled. With
AIS TO DTE
enabled, a Loss of Sync (LOS) or Loss of Frame (LOF) event from the line causes
Access-T to generate AIS (unframed ALL ONES) to the aux port, as illustrated
in Figure 6-2.

1.
From the Main Menu Line, select
DTE
