Outgoing Trunk Queuing O-2
O-2 Outgoing Trunk Queuing
General Description
This feature allows a user to dial a specified access code and enter a first-in, first-out queue, when encountering a
trunk busy signal. As soon as an OUTGOING TRUNK becomes available, stations in the queue will be called back
on a first-come, first-served basis.
Operating Procedure
When LEAST COST ROUTING - 3/6-DIGIT [L-5] is not provided: 
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.
4. Replace the handset.
When LEAST COST ROUTING - 3/6-DIGIT [L-5] is provided:
1. Dial the trunk access code and receive PBX dial 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.
5. Replace the handset.
Service Conditions
1. After an OUTGOING TRUNK becomes available, the users 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/IMX-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.

O-2 Outgoing Trunk Queuing
Service Conditions (cont’d)
13. If a user goes on-hook within 6-8 seconds after encountering all trunks busy, OUTGOING TRUNK
QUEUING can be set automatically to the station.
14. The station is set for OGQ for a minimum of 30 seconds to one hour, maximum. This time is adjustable
through the System Data base. After this time, OGQ will be cancelled automatically.
15. ACCOUNT CODE [A-18] and FORCED ACCOUNT CODE [F-7] information can be recorded on
SMDR [S-10], when used in conjunction with OGQ.
16. This feature can be activated when using a trunk in the remote node via FCCS link.
17. The maximum number of the OGQs stations is 1,024 within the FCCS network (NCN can manage a
maximum of 1,024 calls).
18. OGQ data is transmitted to and stored in the Network Control Node (NCN). Therefore, all the OGQ data
will be cleared by the system initialization of the NCN.
19. When the access to the NCN is impossible (system down or cable disconnection or any trouble has
happened), the user cannot set or cancel OGQ data. (After dialing the access code or pressing the feature
keys for set/cancel OGQ, the user hears the reorder tone.)
20. When the trunk becomes idle status after the NCN is recovered, the call in the queue will be called back,
if data has not been cleared. If data has been cleared, the call is cancelled automatically.
Interactions
1. Dial pad operation for Dterm sets may be used. A FLASH BUTTON [F-3D] must be programmed to a
programmable line/feature key.
2. OGQ-AUTOMATIC may operate with either same or separate access codes. If the Automatic option is
chosen, service set tone will be sent when encountering an all trunks busy situation. No dial pad operation
will be required.
3. When testing OGQ, at least one trunk of the trunk group being tested must be engaged in a station-to-trunk
or trunk-to-trunk connection. Use of the MB key only on the trunk circuit card will not allow OGQ to test
and operate properly.
