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.
Programming
STEP 1:ASYD - System Data 1, Index 73, bits 0 & 1. For PAGING function only, assign data “00”.
STEP 2:ARTD - Assign the Paging route as shown below:
RT:  1
1-OSGS :2 2-ONSG :3 4-INSG :3 5-TF :1 6-TCL :8
7-L/T :1 8-RLP :2 15-LSG :0/1 44-PRV :1
STEP 3:AT R K - Assign the LEN, Paging Trunk Route Number, Trunk Number, and Tenant Number.
STEP 4:MBTK - Assign the Make Idle status to the Paging trunks.
STEP 5:ANPD - Assign a level for trunk access. Assign Connection Indexes, CI = N, H; Normal (N), and
Hooking (H). Assign the Number of Necessary Digits according to a predetermined numbering plan.
Busy Lamp Field is not activated. 
STEP 6:ASPA - Assign the PAGE ACCESS code. Type of Service, SRV = OGC (Outgoing Call). Assign the
proper route number associated with this access code. Assign Connection Indexes, CI = N, H; Normal
(N) and Hooking (H). 
STEP 7:ARSC - Assign to the station that is allowed access to paging trunks a Route Restriction Class (RSC)
that is allowed these routes in Route Restriction Indexes (RRI) 2 & 3. 
FCCS Programming 
No unique programming is required for the FCCS network.

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].

Passing Dial Tone P-2
Interactions (cont’d)
2. The associated programming that should be examined is ATTENDANT CONSOLE [A-3], TOLL
DENIAL/TOLL DIVERSION [T-7], TOLL RESTRICTION-3/6 DIGIT [T-8], LEAST-COST
ROUTING-3/6 DIGIT [L-5], CLASS OF SERVICE-INDIVIDUAL [C-17], and the various trunk access
features. 
3. NIGHT CONNECTION FIXED/FLEXIBLE [N-1, 2]: The NIGHT CONNECTION FIXED/FLEXIBLE
stations cannot pass dial tone to another station.
4. ATTENDANT NIGHT TRANSFER [A-19]: The ATTENDANT NIGHT TRANSFER station cannot
pass dial tone to another station. 
5. When LEAST-COST ROUTING-3/6 DIGIT [L-5] is programmed, the ATDP tables will be affected.
During feature operation, the Attendant will dial the route access code and then release dial tone to the
station. Because that route is assigned in ARNP tables against the LCR (S) access codes, the ATDP tables
must also use the LCR (S) access code. For example, the Attendant dials 81 and releases. The station dials
1-516-753-7526. ATDP must be programmed as DC: 9151 and TDI: 1, allowed; not as DC: 81151.
(ARNP for the route in this example is assigned with the access code = 9.) 
Programming
STEP 1:ASYD - System Data 2, Index 15, Bit 3. Toll restriction on an outgoing call placed by PASSING DIAL
TONE. 0/1: Valid/Invalid.
STEP 2:ARSC - Construct a Route Restriction Class (RSC) that will allow outgoing access to the various
routes via Route Restriction Index (RRI) 2, via the Attendant Console. Be sure to assign RRI 3 as data
“0 or 2”, connection restricted.
STEP 3:ASDT - Assign to the station a Route Restriction Class (RSC) that allows outgoing access to the
various routes via the Attendant Console. 
STEP 4:AT D P - For those Route Restriction Classes that will receive dial tone from the Attendant Console,
construct allow tables. The system does not pass the RSC of the Attendant Console to the restricted
station. It bypasses the RRI 3 restriction and instructs the system to look at the ATDP tables for that
RSC and govern connections accordingly.
FCCS Programming 
No unique programming is required for the FCCS network.

P-3 Power Failure Transfer
P-3 Power Failure Transfer
General Description
This feature provides for certain specified trunks to be automatically connected to designated stations in the event
of a loss of AC power. It is normally used when the system is not equipped with reserve power.
Station Application
Operation is automatic if there is loss of input power to the system.
Service Conditions
1. If the Central Office is wired ground start, stations must be equipped with ground buttons to complete calls
over the exchange network.
2. Power failure station lines should not be wired to common bells. These require outside power sources and
will not operate.
3. Type of telephone set (DP or DTMF) connected to CO line via POWER FAILURE TRANSFER shall
correspond to the signaling system of the Central Office.
4. The maximum number of POWER FAILURE TRANSFER circuits per PIM is 24 (12 circuits per
package).
5. The Power Failure Trunk (PFT) and associated Central Office Trunk should be in the same PIM.
6. When the POWER FAILURE TRANSFER feature is activated, telephone service is limited to incoming
calls and/or outgoing calls via the serving Central Office. DID calls cannot be received.
7. D
terms cannot be used as Power Failure stations.
8. All calls in progress and/or established calls are lost when a POWER FAILURE TRANSFER occurs.
When commercial power is restored, the NEAX2400 IMX is automatically reinitialized. Back-up service
is provided via the HDD unit to retain the following features: 
CALL FORWARDING [C-2, C-2D, C-3, C-3D, C-5, C-5D]
SPEED CALLING - GROUP [S-23]
SPEED CALLING - STATION [S-21]
NAME DISPLAY DATA [N-28]
Interactions
1. A PFT circuit card is required. 
2. The POWER FAILURE TRANSFER station and Central Office trunk must be on the same Module
Group.
3. When power is lost and the POWER FAILURE TRANSFER (PFT) feature is activated, telephone service
is limited to incoming and outgoing calls via the predesignated PFT stations. 
4. DID service will be lost, as this service is dependent on the operational status of Incoming Register Trunks
(IRTs). 
5. When power is lost, all calls (station-to-station and station-to-trunk) are lost. When power is restored, PFT
calls will stay up until manually disconnected by the participants. Service to the PFT stations is then
restored to normal.
Programming
No programming is required.

P-6  Pushbutton to Rotary Conversion
General Description
This feature allows DTMF telephones to be used when DTMF signaling is not provided or are not available from
the Central Office and/or TIE Line.
Operating Procedure
Users dial the desired telephone numbers.
Service Conditions
1. PUSHBUTTON TO ROTARY CONVERSION is software controlled on a per-trunk route basis.
2. See UNIVERSAL SENDER [U-3] for reference. 
3. When the following combination of data settings are assigned, the PB station cannot originate a call:
ASDT - TEC = 3 (DP/PB) station data for the calling station
ASPA - SSC = OGC/OGCA
ARTD - CDN1: OSGS = 2 (second dial tone)
CDN2: ONSG = 2 (PB, 60 msec. Interruption or CCIS No. 7)
Interactions
1. Each 8RST circuit card contains four register and four sender circuits. Each register circuit can accept
either push-button or rotary dial pulses. The senders can outpulse push-button or dial pulse signals and are
used with the ATTENDANT CONSOLE [A-3], LEAST-COST ROUTING-3/6 DIGIT [L-5], SPEED
CALLING-SYSTEM, STATION, GROUP [S-3, 21, 23], OUTGOING TRUNK QUEUING [O-2], OFF-

2. Register circuits are located on the first four levels (0-3), and sender circuits are located on the last four
levels (4-7) of the 8RST circuit card.
3. Each register may be assigned as either an outgoing or an incoming register. Incoming calls have priority
over outgoing calls. Thus, a register programmed as outgoing may serve as an incoming register when
none are available. However, an incoming register will never serve as an outgoing register.
Programming
STEP 1:ASYD - System Data 2, Index 2, Bit 0. Sender signal for station is DP/PB? 0/1: DP/PB. Always assign
as data “0”. Assign on a per-tenant basis. This Bit takes priority when ARTD, CDN 2:ONSG is
assigned as data “3”, DP/PB. 
STEP 2:ASDT - Assign single-line stations a Telephone Equipment Class (TEC) of Push-button (PB) TEC = 2
or dial pulse/push-button (DP/PB), TEC = 3.
STEP 3:AT R K - Assign Originating Register Trunks (ORT) to the system in a quantity calculated from
expected traffic. Registers are located on levels 0-3 of any 8RST circuit card.
