INTER-OFFICE OFF-HOOK QUEUING -PRI
I-36 INTER-OFFICE OFF-HOOK QUEUING-PRI
1. General Description
This feature can be employed in a Main-Satellite configuration to allow a satellite station user to queue for
LEAST COST ROUTING-3/6-DIG IT-P RI [L-31 ] at the main location . This feature can also be use d when all
outgoing ISDN trunks are concentrated at the main location.
Note 1: There are a maximum of 32 “Queuing” per Module Group (MG) available in the system. Therefore,
only 32 stations/MG may utilize OFF-HOOK QUEUING [O-7],-PRI [O-28], OUTGOING TRUNK
QUEUING [O-2], and-PRI [O-24] simultaneously.
Note 2: The connecting patterns available for this service are shown below:
• Non-ISDN trunk to ISDN trunk
• CCIS trunk to ISDN trunk
• ISDN trunk to Non-ISDN trunk
• ISDN trunk to CCIS trunk
• ISDN trunk to ISDN trunk
2. Operating Procedure
Operation at the Main location:
1. The Main location receives dialed digits from the Satellite location via ISDN trunk (a TANDEM TIE
TRUNK [T-1]).
2. The Main location determines that no ISDN trunks are available and places the call in an available “Hold
on Queue”.
3. The Main location returns Service Set Tone to the Satellite caller.
4. The Satellite caller remains off-hook, and waits for the call to be completed. (When an ISDN trunk becomes
available, the Satellite caller will be connec ted.) Note
5. If there are no “Hold on Queue” available, the Main l ocation will return Reorder Tone to the S atellite caller.
6. If the Satellite caller goes on-hook (ISDN trunk releases) while in queue, the assigned “Hold on Queue” is
cleared.
Note: If the Incoming Tie trunk is a “Loop” signal trunk, the caller will hear Service Set Tone while waiting in
queue for a maximum of three minutes. After this period, the trunk will automatically be released.
