Off-Hook Queuing - CCIS O-11
O-11 Off-Hook Queuing - CCIS
General Description
This feature allows a user in a CCIS network to remain off-hook and automatically enter a first-in, first-out queue
at the calling and distant nodes when an all-trunk-busy condition has been encountered. As soon as an outgoing trunk
becomes available, the off-hook station is connected to that trunk through CCIS.
Operating Procedure
1. Dial the trunk access code and the desired number.
2. The distant PBX determines that no trunks are available and automatically places the call in an available
queue slot.
3. The calling party receives service set tone and remains off-hook.
4. When a trunk becomes available, the dialed number is automatically forwarded.
Service Conditions
1. This feature is used in conjunction with LEAST-COST ROUTING-3/6 DIGIT (LCR) [L-5].
2. A maximum of 256 stations at each office can use OFF-HOOK QUEUING - CCIS simultaneously.
3. The queue slots for OFF-HOOK QUEUING - CCIS are used in common with OUTGOING TRUNK
QUEUING [O-2] and OUTGOING TRUNK QUEUING - CCIS [O-12].
4. If no queue slots are available, the user will receive a Trunk Busy signal.
5. The LCR Route Restriction Class can provide the OFF-HOOK QUEUING - CCIS option.
6. OFF-HOOK QUEUING - CCIS and OUT-GOING TRUNK QUEUING [O-2, O-2D] services are
mutually exclusive.
7. ACCOUNT CODE [A-18] and FORCED ACCOUNT CODE [F-7] information can be recorded on
STATION MESSAGE DETAIL RECORDING [S-10] when used in conjunction with OFF-HOOK
QUEUING - CCIS.
8. OFF-HOOK QUEUING - CCIS can be set concurrently to a maximum of eight connecting PBX systems
(including the self node).
9. OFF-HOOK QUEUING - CCIS is, by definition, set to a connecting CCIS node.
10. A maximum of 1024 stations per system can use OFF-HOOK QUEUING - CCIS simultaneously.
Interactions
1. UNIVERSAL SENDER [U-3] must be provided first.
2. The PBX attempts trunk seizure every four seconds until the connection has been completed.
3. LEAST-COST ROUTING-3/6 DIGIT [L-5] information will be applied to these attempts. Therefore,
OUTGOING TRUNK QUEUING [O-2, 12] will be set against all routes in the outgoing pattern routing
(OPR).
4. If all queuing memory slots are in use, the user will receive a trunk busy signal.
5. The time a call may remain in queue is unlimited.
