2.5.4.6 Trunk Busy Out
Description
The PBX can monitor the loop current sent through analogue trunks, preventing users from seizing trunks
where a loop current is not detected. When loop currents are not detected, trunks are set to Busy Out status,
and become unable to make or receive calls. A trunk in Busy Out status cannot be used for making calls as a
TIE line, as part of a trunk group, or with the ARS feature, and cannot receive trunk calls. If a user tries to seize
a trunk set to Busy Out status, the user will hear a reorder tone.
This is useful if some or all trunks are occasionally unavailable because of problems with the external
telecommunications environment.
Conditions
•
This feature is not available for the following LCOT cards:
KX-NCP1180NE (LCOT4)
KX-TDA0181NE (LCOT16)
KX-TDA0180NE (LCOT8)
KX-TDA0183NE (LCOT4)
•
Loop current detection is performed on active trunks whenever the trunk is seized and/or at fixed intervals.
•
When a trunk is in busy-out status, loop current detection is performed at fixed intervals, returning the trunk
to in-service status once a loop current is detected. An extension assigned as the manager can manually
change the trunk back to in-service status.
•
Trunk status changes are recorded in the error log of the PBX.
•
Busy Out status is maintained even when the PBX is reset.
•
Busy Out status is cleared when:
–
a call is successfully received (i.e., a loop current is detected) on that trunk.
–
the S-CO button for that trunk is pressed and a loop current is detected.
