Deactivating the Alarm Relay
for Carrier-Mounted
DSU/CSUs
The Alarm Cut-off command forces a deactivation of
the alarm relay on the 3000 Series Carrier during an alarm
condition. Since this function only affects the 3000 Series
Carrier, it is only available for carrier-mounted

Appendix C, Configuration Options).
To deactivate the alarm relay,
1. From the top-level menu screen, press the
key
until the Ctrl selection appears on the screen.
