on a first-come, first-served basis.
Operating Procedure

1. Dial the trunk access code and receive busy tone.
2. Press the switch hook and receive special dial tone.
3. Dial the OUTGOING TRUNK QUEUING (OGQ) access code and receive service set tone.

2. Dial the desired number and receive busy tone.
3. Press the switch hook and receive special dial tone.
4. Dial the OGQ access code and receive service set tone.

Service Conditions
1. After an OUTGOING TRUNK becomes available, the user's station will ring for 30 seconds. If not
answered within that time, the station will automatically be dropped from the queue.
2. When this feature is used in conjunction with SPEED CALLING - SYSTEM [S-3], or LEAST COST
ROUTING [L-5], where a sender is involved, the sender will automatically dial out the called subscriber
number when the handset is lifted.
3. If the user wishes to remove himself from the queue prior to being rung, the specified cancellation code
must be dialed.
4. Individual stations may only initiate one outgoing trunk queue at a time. Subsequent attempts will result
in a reorder tone.
5. Stations may be restricted from using this feature in CLASS OF SERVICE - INDIVIDUAL [C-15].
6. This feature is not available for an ATTENDANT CONSOLE [A-3].
7. The maximum number of simultaneous OGQs per system:
1 IMG: 64 calls
4 IMG/IPX-U: 256 calls
The queue slots are used commonly by OFF-HOOK QUEUING [O-7], INTER-OFFICE OFF-HOOK
QUEUING [I-11], and OGQ [O-2, 2D, 16].
8. CALL PICKUP - GROUP [C-7] cannot be used to answer a call directed to another station using OGQ.
9. OGQ is common to all Central Office-type trunk groups (COT, TIE, FX, WATS, etc.) in the system.
10. OGQ call back will return to the originating station, not the CALL FORWARDING [C-2, 3, 5] terminating
station.
11. OGQ is denied to a station line when the CALL BACK [C-1] or CALL HOLD [C-6] feature is already
activated.
12. The Attendant cannot CAMP-ON [A-1] a call to a station that has activated OGQ.
