Off-Hook Queuing O-7
O-7 Off-Hook Queuing
General Description
This service allows a user, upon encountering a trunk-busy condition, to remain off-hook and automatically enter a
first-in, first-out queue. As soon as an outgoing trunk becomes available, the switch connects the next call to this
trunk.
Operating Procedure
1. Lift the handset; receive a dial tone.
2. Dial the Outgoing Call access code and the desired number (LCR access).
3. The NEAX2400 IPX determines that no trunks are available and places the call in an available queue slot.
4. The caller receives service set tone; remains off-hook and waits.
5. When a trunk becomes available, the dialed number is automatically sent forward.
Service Conditions
1. This feature is usually used in conjunction with LEAST COST ROUTING - 3/6-DIGIT [L-5].
2. The maximum number of simultaneous OFF-HOOK QUEUEs per system:
1 IMG: 64 calls
4 IMG/IPX-U: 256 calls
3. The queue slots are used commonly by OFF-HOOK QUEUING, OUTGOING TRUNK QUEUING [O-
2] and INTER-OFFICE OFF-HOOK QUEUING [I-11].
4. If no queue slots are available, the user will receive busy tone.
5. Route Class of the LCR can give the choice of the OFF-HOOK QUEUING.
6. CLASS OF SERVICE - INDIVIDUAL [C-15] is applied for each station. This class of service is different
from the class of service for OUTGOING TRUNK QUEUING [O-2]. Both services are mutually
exclusive.
7. When automatic outgoing queuing (on-hook queuing) is in service (tenant basis), OFF-HOOK QUEUING
service is not effective.
8. ACCOUNT CODE [A-18] and FORCED ACCOUNT CODE [F-7] information can be recorded on
SMDR [S-10], when used in conjunction with OFF-HOOK QUEUING.
9. This feature can also be activated when using a trunk in the remote node via FCCS link.
