52.2 Viewing NFAS Groups and D-Channel Status
You can view the status of the device's D-channels and NFAS groups, if configured. The
status of a D-channel and NFAS group can be "In Service" or "Out of Service" and the D-
channel can be "Primary" or "Backup".
You can also perform a switchover from active and to standby D-channel belonging to the
same NFAS group. This is done using the Switch Activity button. For more information,
see ''Performing Manual D-Channel Switchover in NFAS Group'' on page 461.
Note: This page is applicable only to T1 ISDN protocols supporting NFAS, and only if
the NFAS group is configured with two D-channels.
