Off-Hook Queuing O-7
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.

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.

Paging Access P-1
Interactions (cont’d)
5. For simple PAGING ACCESS [P-1], assignments in ASFC are not required. Refer directly to the other
Paging features, such as PAGING TRANSFER [P-10]. 
6. The Attendant can dial the PRIORITY PAGING [P-30] access code and release a station.
7. When disconnecting from a Paging trunk, the trunk becomes idle immediately. 
8. Paging is possible from a CONSULTATION HOLD [C-17]. Station A places Party B on soft hold and
dials the access code to the Paging trunk. A momentary pressing of the switch hook disconnects the Paging
trunk immediately and reconnects Party B to Station A. 
9. CALL HOLD [C-6]: A Paging trunk cannot be placed on call hold.
10. BUSY is displayed on the D
term LCD display when the Paging trunk is busy. Reorder tone is returned.
11. If PRIORITY PAGING [P-30] is used with PAGING ACCESS [P-1]; ARTD, CDN 6 must be assigned
as data “8”, Page with ringback tone. System Data 1, Index 73 affects the operation of Page routes assigned
Page with ringback tone. Therefore, if PRIORITY PAGING [P-30] is used with PAGING ACCESS [P-
1], then MEET-ME PAGE [M-1, 11] and PAGING TRANSFER [P-10] are not available to the system.
12. PRIORITY PAGE [P-30] access will not disconnect an Attendant Console engaged in a Paging trunk
connection.

P-2 Passing Dial Tone
P-2 Passing Dial Tone
General Description
This feature allows the Attendant to PASS DIAL TONE to a restricted user, enabling that user to place a call that
would normally be restricted.
Operating Procedure
1. Restricted user dials Attendant.
2. Attendant presses ANSWER or ATND key; tenant number, trunk route restriction class and telephone
number are displayed.
3. Obtain call details.
4. Dial central office access code; tenant number, and trunk identification number are displayed.
5. Press RELEASE key; user hears dial tone.
6. User places the call.
Service Conditions
1. This feature permits PASSING DIAL TONE to restricted and unrestricted stations only by the Attendant.
2. When LEAST COST ROUTING - 3/6-DIGIT [L-5] is provided in the system, the Attendant cannot pass
dial tone. The call must be completed via the ATTENDANT CONSOLE [A-3].
3. TOLL RESTRICTION [T-7] is activated via system programming for the PASSING DIAL TONE
feature.
4. The PASSING DIAL TONE feature is limited by the number of trunks that can be accessed by the
Attendant and the Class of Service restrictions of the station.
5. Restriction from Outgoing Calls: This feature can be overridden by the use of the PASSING DIAL TONE.
6. The Attendant is allowed to pass dial tone to any station that has a class of service that allows normal direct
dial access capabilities to the trunk group seized by the Attendant.
7. Any non-restricted station can dial through over the selected outgoing trunk. The type of address signals
sent to the called location are determined by the trunk route class data.
8. Where SMDR [S-10] is provided, through-dialed calls are charged to the calling station line.
9. This feature is available when the numbering plan for call origination is Outgoing Call (OGC) or Outgoing
Call Alternative (OGCA), and the answer-back signal is the second dial tone (mark-out method).
10. When placing outside calls, activation of the TOLL RESTRICTION - 3/6-DIGIT [T-7] is determined by
System Data of the calling station on a tenant basis.
11. If TOLL RESTRICTION- 3/6-DIGIT [T-7] is not activated via System Data, neither the 3-digit area code
nor the 6-digit area and office code are restricted.
12. If TOLL RESTRICTION- 3/6-DIGIT [T-7] is activated via System Data, the call will be restricted when
the calling party dials the restricted area code.
Interactions
1. Any station that is restricted from a route may receive access to that route by the Attendant Console. A
station that is toll restricted will not be able to place calls to destinations normally restricted by having the
Attendant Console pass dial tone. The same ATDP tables will apply to that station. The Attendant Console
must dial the number for the station when that station is toll restricted. See NON-DELAY OPERATION
[N-3].
