For DIOD trunks using TN464F (or later release) or TN2464, displays only when
the Group Type field is
diod and the Trunk Signaling Type field is pulsed, cont,
or
dis.
If a switch generates an outgoing seizure when a trunk is busied out, the seizure
will probably cause alarms at the far-end switch, perhaps leading to a far-end
maintenance busy out, unless the far-end 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 switch 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 the switch administration software.
Shuttle
This field appears when the Country field is
15 and the Outgoing Dial Type field
is
rotary. It can be administered on TN464D (or later release) or TN2199 circuit
packs.
Valid entries Usage
near-end
Enter near-end if this switch generates an outgoing seizure
when a trunk is maintenance busied but the far-end switch
does not. The seizure is maintained until the maintenance
busyout is released.
far-end
Enter far-end if the far-end switch generates an outgoing
seizure when a trunk is maintenance busied but this switch
does not.
both-ends
Enter both-ends if both this switch and the far-end switch
generate an outgoing seizure when a trunk is maintenance
busied.
Valid entries Usage
y/n
Enter y to enable MF shuttle signaling.
