Off-Hook Queuing O-7
O-7 Off-Hook Queuing
General Description
This service allows a 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
1. Lift the handset; receive a dial tone.
2. Dial the Outgoing Call access code and the desired number (LCR access).
3. The NEAX2400 IMX 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. The maximum number of simultaneous OFF-HOOK QUEUEs per system:
1 IMG: 64 calls
4 IMG/IMX-U: 256 calls
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 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.
9. This feature can also be activated when using a trunk in the remote node via FCCS link.
Node A Node BFCCS linkBusy
Busy
Busy Example
: Node A and Node B are in an FCCS network.
 Although a station belonging to Node A tried to call outside using a trunk belonging to Node B, all the trunks are busy. 
The call can be in the queue using this feature.

O-7 Off-Hook Queuing
Service Conditions (cont’d)
10. The maximum of number of the OGQ stations is 1,024 within the FCCS network (NCN can manage a
maximum of 1,024 calls).
11. 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.
12. When the access to the NCN is impossible (system down, cable disconnection or trouble has occurred),
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.)
13. 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. 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 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].
7. Do not disable constant service set tone by changing System Data 1, Index 42, Bit 7 to data “1”. This
changes constant service set tone to burst special dial tone, and special dial tone to burst special dial tone,
followed by constant dial tone. This will also disable TANDEM OFF-HOOK QUEUING. 
Programming
STEP 1:ASYD - System Data 2, Index 4, Bit 1. Enable Automatic OUTGOING TRUNK QUEUING? 0/1:
OFF-HOOK QUEUING/Automatic OUTGOING TRUNK QUEUING. (OFF-HOOK QUEUING and
Automatic OUTGOING TRUNK QUEUING are mutually exclusive.) Assigning data “0” allows OFF-
HOOK QUEUING. 
STEP 2:ASFC - Assign a Service Feature Class that allows SFI 21 to stations that will have OFF-HOOK
QUEUING.
STEP 3:ARTD - Routes to be used for OFF-HOOK QUEUING must be flagged in CDN 9:TQ. Also allow
OUTGOING TRUNK QUEUING to the LCR(s) flag route.
FCCS Programming 
This data setting describes only the additional or replacement commands used to activate FCCS
services. When used as an FCCS feature, these commands replace the non-network commands (for
example, AAED is replaced by AAEDN). Note that the data setting for FCCS service varies depending
on the node.
 (Note 1)
STEP 1:ASYDN - This data must be assigned to the NCN. System Data 1, Index 41: Designate the Trunk
Queuing Override Timer.
STEP 2:ASPAN - This data must be assigned to the NCN.

P-1 Paging Access
P-1 Paging Access
General Description
This feature provides both ATTENDANT CONSOLE [A-3] and users dial access to PAGING equipment.
Operating Procedure
1. Go off-hook; receive dial tone. 
2. Dial the Paging access code; receive ringback tone for several seconds.
3. Connection to Paging equipment is established.
Service Conditions
1. Amplifiers and speakers must be customer provided.
2. One trunk circuit is required for each Paging Access.
3. Where TENANT SERVICE [T-12] is provided, separate access codes and hardware should be provided
for each tenant.
4. Maximum Paging Access code is 3 digits.
5. ALL ZONE PAGING [A-53]: If the system provides multi-zone Paging with a separate direct access code
assigned for each area, stations or Attendants can use all-zone Paging by dialing a special access code
common for all Paging systems.
6. PRIORITY PAGING [P-30]: A predetermined station or the Attendant can preempt a Paging trunk that is
connected to any station.
7. Loop signaling is the recommended signaling type.
8. PAGING ACCESS [P-1], PAGING TRANSFER [P-10] and RADIO PAGING [R-16] are provided to the
paging station and the paged station in FCCS nodes.
9. When PAGING ACCESS [P-1]/PAGING TRANSFER [P-10]/RADIO PAGING [R-16] service is set to
a station in the remote node or the PAGING ACCESS [P-1]/PAGING TRANSFER [P-10]/RADIO
PAGING [R-16] call is answered from the remote node via FCCS link:
a.) the logical route number should be applied to each physical route that provides the service.
b.) the restriction of route-to-route connection between FCCS nodes should be released.
10. The same paging route cannot be used by another station while the paged station does not answer the page
activated using the route. However, the paging activation is automatically cleared when the call is not
answered within a predetermined time.
11. A user can page one station at a time.
Interactions
1. MEET-ME PAGING [M-1, 11] and PAGING ACCESS [P-1] can be provided simultaneously in the same
system. 
2. To directly answer PAGING ACCESS [P-1] by the Attendant Console, the Paged party should use the
INDIVIDUAL ATTENDANT ACCESS [I-4] feature.
3. Paging is limited to stations, Attendant Consoles, or TIE trunks. Other parties (CO trunks calls) must have
the Attendant Console or user perform the Paging operation. 
4. BUSY VERIFICATION [B-3], EXECUTIVE OVERRIDE [E-1]: These features will be denied if the
Paging route has been assigned for Privacy. Verify the data in the Assignment of Route Data command,
ARTD, CDN 44:PRV. If CDN 6:TCL is assigned as data “8”, CDN 44:PRV is not required.
