Screen Reference
Trunk Group
Seize When Maintenance Busy
This field only affects ports on TN760C (or later release), TN767, and TN464C (or later release) circuit
packs. It indicates whether this media server or switch generates an outgoing seizure when a trunk in this
trunk group is maintenance busied and whether the far-end server or switch is administered to do
likewise. This supports the Electronic Tandem Network Busyout feature, which is intended to prevent a
far-end server or switch from reporting problems with a trunk that has been removed from service on
your end. This field's setting does not affect the behavior of the far-end server or switch; it controls the
behavior of your media server or switch and defines the expected far-end behavior.
For DIOD trunks using TN464F (or later release) or TN2464, displays only when the
diod and the Trunk Signaling Type field is pulsed, cont, or dis.
Valid entries
near-end
far-end
both-ends
If a media server or switch generates an outgoing seizure when a trunk is busied out, the seizure will
probably cause alarms at the far-end server or switch, perhaps leading to a far-end maintenance busy out,
unless the far-end server or switch is administered to expect this behavior.
If the administered value of this field is either far-end or both-ends, any abnormally long incoming
seizure (including failure to drop from a completed call) is assumed to be the result of a far-end
maintenance busy condition. Note that this assumption may be incorrect, since the abnormally long
seizure may actually be due to failure of the trunk circuit. Regardless of the cause of the abnormally long
seizure, your server running Communication Manager does the following things:
1
Generates a warning alarm indicating that the trunk is assumed to be maintenance busy at the
far-end
2
Removes the trunk from service
3
Keeps the trunk out of service until a far-end disconnect is received
Allowable values depend on the entry in the Direction field: check the online help in Avaya
Communication Manager.

Usage
Enter near-end if Communication Manager generates an outgoing
seizure when a trunk is maintenance busied, but the far-end server
or switch does not. The seizure is maintained until the maintenance
busyout is released.
Enter far-end if the far-end server or switch generates an outgoing
seizure when a trunk is maintenance busied, but this server running
Communication Manager does not.
Enter both-ends if both this server running Communication
Manager and the far-end server or switch generate an outgoing
seizure when a trunk is maintenance busied.
