Inter-Office Off-Hook Queuing I-11
I-11 Inter-Office Off-Hook Queuing
General Description
This feature can be employed in a Main-Satellite configuration to allow a Satellite user to queue for LEAST COST
ROUTING - 3/6-DIGIT [L-5] at the Main location. This feature can also be used when all outgoing facilities are
concentrated at the Main location.
Operating Procedure
Operation at the Main location
1. The Main location receives dialed digits from the Satellite location via a TANDEM TIE TRUNK [T-1].
2. The Main location determines that no trunks are available and places the call in an available hold on queue
slot.
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.
5. If there are no hold on queue slots available, the Main location will return reorder tone to the Satellite
caller.
6. If the Satellite caller goes on-hook (TANDEM TIE TRUNK [T-1] releases) while in queue, the assigned
hold on queue slot is cleared.
Service Conditions
1. This feature is usually used in conjunction with LEAST COST ROUTING - 3/6-DIGIT [L-5].
2. The maximum queuing slots per system are: 64 calls for 1 IMG system
256 for 4 IMG/IPX-U system
The queue slots are commonly used by OFF-HOOK QUEUING [O-7], INTER-OFFICE OFF-HOOK
QUEUING [I-11], and OUTGOING TRUNK QUEUING [O-2, 2D, 16].
3. If the incoming tie trunk is a second dial tone signal trunk, the caller will hear service set tone while
waiting in queue for a maximum of 3 minutes. After this period, the trunk will automatically be released.
4. When a trunk becomes available, the dialed number is automatically sent to the connecting Central Office.
5. If all OFF-HOOK QUEUING [O-7] slots are in use, reorder tone (fast busy tone) will be sent to the
Satellite office.
6. This feature can also be activated when using a trunk in the remote node via FCCS link.
