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 B
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).
