Automatic Maintenance Bus y 4

Automatic Maintenance Busy allows the system to take a malfunctioning trunk out
of service for outgoing calls (incoming calls are never blocked). This p revents
faulty outside facilities from causi ng dis r u pt io ns in ou tg oing calling patterns.
For optimal performance, enable Automatic Maintenance Busy for Hybrid/PBX
systems with pooled trunks.
NOTE:NOTE:NOTE:
No more than half of the trunks in a trunk pool are allowed to be placed in
the maintenance busy state at one time unless the central office h as failed
to disconnect a trunk (which prevents anyone from using that trunk) or an
entire trunk module is manually taken out of use (a maintenance-busy state
deliberately caused by the user).
