If installation at both ends of a hop are complete except for connecting to customer inputs/outputs and it is
desirable to have an alarm-free system, alarm reporting on the incomplete connections can be disabled
temporarily through provisioning. You can communicate over the hop even if you do not have the radio
connected to customer DS3 and wayside DS1 inputs; however, you will alarm. On the DS3 Facilities screen,
set XMT ALARM DISABLE and RCV ALARM DISABLE to ON to disable DS3 alarm reporting on the wayside DS1
Facilities screen, set ALARM Lockout to ON to disable alarm reporting for all equipped wayside DS1 lines.
After all customer connections are complete, alarm reporting can be restored to normal.
