General Description
This service allows a station 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
To operate:
1.
Lift the handset; receive a Dial Tone.
2.
Dial the Outgoing Call access code and the desired number (LCR access).
3.
The NEAX2400 ICS 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.
Maximum number of simultaneous OFF-HOOK QUEUES per Module Group is 32.
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 station 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.
Interactions
1.
UNIVERSAL SENDER [U-3] must first be provided.
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 will be set against all routes in the Outgoing Routing
Pattern (OPR).
4.
If all queuing memory slots are in use, the station user will receive a trunk-busy signal.
5.
The time a call may remain in queue is unlimited.
6.
The following features cannot be activated toward the busy station: CALL WAITING-
ORIGINATING [C-31], CALL WAITING-TERMINATING [C-12], ATTENDANT CAMP-ON WITH
TONE INDICATION [A-1], BUSY VERIFICATION [B-3] and EXECUTIVE RIGHT-OF-WAY [E-1].
