Priority Paging P-30
Service Conditions (cont’d)
12. Forced release of a Paging Trunk is processed so that the station connected with that specific Paging Trunk
is regarded as having released. Therefore, after the forced release of the paging trunk, the state of the
station is as follows:
a.) if there is a call on hold: Dial Tone Connection
b.) if there is no call on hold: Recall (Calling Only) 
(Answering - Non-Delay)
Dial Tone Connection (Answering - Delay basis)
(Paging Transfer)
13. Going on-hook by the station after dial tone connection will result in Recall. As the Paging Memory
becomes free after this Recall, a PRIORITY PAGING call can be originated.
14. Forced clearance of the Paging Memory is processed as a time-out of a paging call awaiting answer.
Therefore, after the forced Paging Memory clearance, the state of the station is as follows:
a.) if there is no call on hold: Same as before clearance
b.) if there is a call on hold: Recall 
(Note)
Note:If a Recall cannot be made because of a busy line, etc., the Paging Memory is not cleared until the line is released and
Recall is possible.
15. Both the COT card and the TLT card can be used as the paging trunk.
16. Loop signaling is the recommended signaling type.

Remote Access to System R-2
Interactions
1. The Authorization Code used in conjunction with REMOTE ACCESS TO SYSTEM will not be recorded
in SMDR. System Data 2, Index 3, bit 5 is the only difference between Forced Account Code and
Authorization code. This Bit determines where the dialed code will appear in SMDR. When assigned as
Authorization code, those digits will not appear in SMDR.
2. The additional step of the ARAC command, for DID trunks does not eliminate the need for Forced
Account Code assignments. In addition, Remote Access to System [R-2] via DID requires the use of
Forced Account Codes [F-7].
3. The PBX recognizes a momentary pressing of the switch hook as a disconnect by the remote party.
Therefore, all features activated via a Connection Index of Hooking (H) are not available to the REMOTE
ACCESS TO SYSTEM feature user. A remote access user may participate in a feature that requires a
switch hook flash generated by an internal station. 
4. STATION MESSAGE DETAIL RECORDING [S-10]-REMOTE ACCESS TO SYSTEM outgoing calls
are recorded in SMDR. The field in the SMDR report that lists the calling station will list the route and
trunk number.
5. SPEED CALLING SYSTEM [S-3] and SPEED CALLING-STATION/INDIVIDUAL [S-21, 23] may not
be accessed via REMOTE ACCESS TO SYSTEM [R-2].
6. If the REMOTE ACCESS TO SYSTEM feature is used to call stations internal to the system, allow in
ARSC the Incoming Remote Access route to the RSCs of the station that may be called. 
7. See AUTHORIZATION CODES [A-20] for Check/Sum method assignments.

Restriction from Outgoing Calls R-4
R-4 Restriction from Outgoing Calls
General Description
This feature automatically denies preselected station lines within the NEAX2400 IMX system the ability to place
outgoing calls and/or certain miscellaneous trunk calls without Attendant assistance.
Operating Procedure
Operation is fully automatic that the restricted stations will receive reorder tone upon attempting to place a restricted
call.
Service Conditions
1. This feature is programmable via System Data programming from the MAINTENANCE
ADMINISTRATION TERMINAL (MAT) [M-18].
2. Non-restricted stations within the system can CALL TRANSFER - ALL CALLS [C-11] outgoing calls to
the stations restricted by this feature.
3. Only the Attendant can permit the restricted stations to place outgoing calls via either of the following
features:
PASSING DIAL TONE [P-2] 
NON-DELAY OPERATION [N-3]
4. Refer to CLASS OF SERVICE - INDIVIDUAL [C-15] and DAY/NIGHT CLASS OF SERVICE [D-15]
for further details.
5. Station line access to a given trunk group is controlled by assigning a Route Restriction Class (RSC) to
each line. There can be a maximum of 15 different RSCs (RSC1 - 15) per system, each of which can be
programmed to restrict an assigned station from none, one, or more than one trunk group.
6. Two outgoing trunk group restriction tables are provided per system. The Direct Dial Access table is
indexed when a user dials the trunk group access code and the ATTENDANT CONSOLE [A-3] table is
indexed on Attendant completed calls. The restriction options per RSC can differ per table, thus, allowing
Attendant completion of outgoing calls for the restricted stations.
7. CALL TRANSFER - ALL CALLS [C-11]: If a restricted user calls another station, the called station
cannot use the Call Transfer feature to connect the calling station to a trunk group to which the calling
station is restricted from outgoing calls. If transfer is attempted, the controlling station is rung back.
8. TIE LINE ACCESS [T-3]: If the user accesses a TIE trunk to a distant PBX, access to the public exchange
network can only be controlled by the distant PBX.
9. THREE-WAY CALLING [T-2]: If a restricted user calls another station, the called station cannot add-on
an outside exchange party via a trunk group in which the calling station is restricted from outgoing calls.
An attempt to add-on (SHF) will be ignored.
10. NIGHT SERVICE: Restrictions can be changed for a given station when the system is switched to the
night mode of operation.
Interactions
1. Transferring restrictions may not be desired for a restricted station.
2. CALL TRANSFER-ALL CALLS [C-11]: Station A is allowed access to outgoing on Route 1. Station B
is restricted access for outgoing on Route 1 via RRIs 2 & 3. The unrestricted Station A makes an outgoing
call on route 1 and cannot use the CALL TRANSFER-ALL CALLS feature to connect Station B to Route
1. If CALL TRANSFER-ALL CALLS is attempted, Station A is immediately rung back.

R-4 Restriction from Outgoing Calls
Interactions (cont’d)
3. CONSULTATION HOLD [C-17]: Station A may consult with station B when Route 1 is on Soft Hold. 
4. THREE-WAY CALLING [T-2]: Station A cannot include restricted Station B in a Tree-Way Calling
connection with Route 1.
5. DAY/NIGHT CLASS OF SERVICE [D-15]: Restricted Station B may be allowed access to Route 1 when
the system is placed in the NIGHT mode. See DAY/NIGHT CLASS OF SERVICE [D-15].
6. RESTRICTION FROM OUTGOING CALLS are constructed on a per-route restriction basis. Two Route
Restriction Indexes are constructed: RRI 2, Outgoing Calls via the Attendant Console and RRI 3,
Outgoing Calls via Direct Dial Access.

Rotary Dial Calling R-5
R-5 Rotary Dial Calling
General Description
This feature permits users to originate calls over rotary or push-button lines using Rotary Dial telephones.
Operating Procedure
Users dial rotary telephones in the normal fashion.
Service Conditions
1. Rotary dial telephones installed should be industry standard 10pps instruments.
2. Pushbutton instruments may be used in conjunction with ROTARY DIAL CALLING.
3. It is possible to provide only the ATTENDANT CONSOLE [A-3] with push-button calling, while all other
stations are assigned ROTARY DIAL CALLING. Refer to PUSHBUTTON CALLING - ATTENDANT
ONLY [P-5] for further details.
4. If ROTARY DIAL CALLING is assigned to a line, only Rotary Dial sets can be used on that line.
5. POWER FAILURE TRANSFER [P-3]: Rotary dial telephones must be used as POWER FAILURE
TRANSFER [P-3] stations if the serving central office facility is not arranged for pushbutton calling. A
ground start button on the station set is required if the central office facility uses ground start signaling.
Interactions
1. Rotary-to-Pushbutton conversion may be accomplished by assigning data “2” for CDN 2:ONSG in
ARTD; or assigning data “1” in ASYD, System Data 2, Index 1, Bit 0, and assigning CDN 2:ONSG as
data “3”, DP/PB.
2. See UNIVERSAL SENDER [U-3] for sender programming
3. ROTARY DIAL CALLING may be accomplished via an extension of PUSH-BUTTON CALLING [P-4]
if a Telephone Equipment Class of 3 has been programmed. 
4. The * or # symbols cannot be used as feature activation codes with ROTARY DIAL CALLING.
5. The PBX Originating Registers Trunks (Route 902) can accept both rotary and push-button signals (a
separate register group is not required).

R-6 Route Advance
R-6 Route Advance
General Description
This feature automatically routes outgoing calls over alternate facilities when the first-choice trunk group is busy.
User selects the first-choice route by dialing the corresponding access code, and the equipment then advances
through alternate trunk groups only if the first choice is busy.
Operating Procedure
No manual operation is required.
Service Conditions
1. No indication is provided to a user as to whether the call is routed over first-choice or subsequent choice
facilities.
2. STATION MESSAGE DETAIL RECORDING SYSTEM [S-10] may be used in conjunction with this
feature.
3. Only trunks of the same type may be programmed for ROUTE ADVANCE.
4. Careful consideration should be given to the use of FX trunks as an alternate facility. These lines require
outpulsing of digits for long distance which the user may not dial, because he will not know he is
connected to such a facility.
5. The maximum number of routes to be included in a single ROUTE ADVANCE group is 15.
6. The total number of routes that can be contained in all ROUTE ADVANCE groups is 31.
7. The same route can be included in two or more alternative groups.
8. The maximum number of trunks to be included in a route is 255.
9. No code conversion capability is provided with ROUTE ADVANCE; therefore, the exact digits (after the
access code) the user dials will be sent over the selected trunk, regardless of the trunk group used. The user
will not know what trunk group is selected; therefore, only those trunk groups that accept the same dialing
format may be assigned to a given ROUTE ADVANCE group.
10. ROUTE ADVANCE occurs only when the dialed code accesses the first-choice trunk group in the
ROUTE ADVANCE list.
11. In most cases, FX trunk groups to a Foreign Numbering Plan Area do not require the dialing of the FNPA
area code. Therefore, these FX trunks may not be used in the same ROUTE ADVANCE list with local
exchange or WATS trunks.
12. TIE Lines cannot be assigned to a ROUTE ADVANCE list that includes CO, FX, or WATS trunk groups.
13. The dialing party may be either a station line, ATTENDANT CONSOLE [A-3], or a TIE trunk line.
14. When using the FCCS network, the outgoing call using a trunk in the remote node is available. Therefore,
Route Restriction class data must be identical in the FCCS network. For more detailed information, see
the NEAX2400 IMX Fusion Network System Manual.
Interactions
1. When OUTGOING TRUNK QUEUING [O-2] is assigned with the ROUTE ADVANCE feature, if all
trunk groups in one ROUTE ADVANCE list are busy, the call queues on the first-choice trunk group.
Each time the system checks for an available trunk, only the first-choice trunk group is scanned; if a trunk
is not available, the call remains in queue.
