Automatic Maintenance Busy - AT&T MERLIN LEGEND Release 2.0 Programming Summary Manual

Basic System Operating Conditions

Automatic Maintenance Busy

Automatic Maintenance Busy allows the system to take a malfunctioning trunk
out of service for outgoing calls. (Incoming calls are never blocked.) This
protects against disruptions in outgoing calling patterns that are caused by
faulty outside facilities.
For optimum performance, enable Automatic Maintenance Busy for
Hybrid/PBX systems with pooled trunks.
NOTE:
No more than 50% of the trunks in a trunk pool are allowed to be placed
in the maintenance-busy state at one time unless the central office has
failed to disconnect a trunk (which prevents anyone from using that trunk)
or an entire trunk module is manually taken out of use (a user-imposed
maintenance-busy state).
