Route Advance R-6
Interactions (cont’d)
2. TOLL RESTRICTION - 3/6 DIGIT [T-6] may be used in conjunction with ROUTE ADVANCE. Only
routes of the same type may be used in ROUTE ADVANCE. Two differently labeled C.O. trunks, such
as, DDD and WATS may be in the same group.
3. There is no digit translation available for this feature. The dialed digits must be usable by whatever route
is available.
4. This feature is available for a station activating CONSULTATION HOLD [C-17]. However, in the
following cases, ROUTE ADVANCE is not activated, and the user receives reorder tone:
a.) when either the first-choice trunk group or alternate trunk group is restricted by TOLL DENIAL
[T-6].
b.) when both the first-choice trunk group and alternate trunk group are busy or restricted by TOLL
DENIAL [T-6].
5. ROUTE ADVANCE is not activated on PAGING TRANSFER [P-10] or RADIO PAGING [R-16] routes.
Therefore, the caller receives reorder tone when the first trunk group is busy or restricted by TOLL
DENIAL [T-6].

R-7 Remote Maintenance
R-7 Remote Maintenance
General Description
This feature allows office data changes or reassignments to be performed without a site visit by service personnel,
and can be used to detect fault tendencies before they affect service. One REMOTE MAINTENANCE center can
service an unlimited amount of systems, thus reducing the amount of personnel needed to maintain each site.
Operating Procedure
The operation of this feature involves the use of the MAINTENANCE ADMINISTRATION TERMINAL (MAT)
[M-18].
Service Conditions
1. The following additional equipment is required for this feature:
a.) a modem at the maintenance center, and one at each remote site,
b.) a dedicated or non-dedicated telephone line for each remote site.
2. The following operations can be executed from the REMOTE MAINTENANCE location:
a.) list of all system data (line, trunk, etc.)
b.) retrieval of fault data
c.) retrieval of traffic management information
d.) testing of system operation
e.) deletion or addition of system data (line, trunk, etc.) using a pre-programmed security password
3. The following three facility methods are available to interface with a remote test location:
a.) dedicated connection
b.) dial-up connection - TIE Line
c.) dial-up connection - CO Line
4. Maintenance testing can be performed at a remote central facility, using the MAT [M-18] to evaluate a
trouble report, prior to the dispatching of a repair person to the customer location.
5. Two MATs can access a system simultaneously, provided they are not using the same command at the
same time.
Interactions
APSW must be assigned before allowing the password function in the ASYD command. If password is allowed in
ASYD before APSW is assigned, Error Message 0550 “Password not yet assigned”, will be displayed.

Radio Paging R-16
R-16 Radio Paging
General Description
This feature allows users dialing access to customer-owned RADIO PAGING equipment and to selectively tone or
voice/tone alert individuals carrying pocket RADIO PAGING receivers. The paged party may be connected to the
paging party by going to the nearest telephone and dialing a unique answer-back code.
Operating Procedure
To page:
1. Paging user dials the RADIO PAGING access code; receives an acknowledgment tone from the radio
equipment.
2. Paging user dials the radio number of desired party; receives ringback tone from the radio equipment. 
3. Paging user hangs up and waits for an answer signal.
To answer:
 Using OGC access code, a paging station accesses Radio Paging equipment whether or not the automatic 
answer function is provided. (System Data 1, Index 73, b4 = 1 or 0.)
1. Paged party dials the RADIO PAGING answer code.
2. Paged party receives special dial tone.
3. Paged party dials his own individual radio (beeper) number. 
4. Paged station is rung; the paged party receives ringback tone. 
Note:This operation is not available when assigning System Data 1, Index 73, b4 = 1. Only Non-Delay operation is
available.
5. Paging station is connected to the paged party.
 Using LCR/LCRS access code, a paging station accesses Radio Paging equipment providing the automatic 
answer function. (System Data 1, Index 73, b4 = 1.)
1. Paged party dials the paging station number/individual attendant number which is displayed on the radio
pager (beeper).
2. Paging station/attendant is rung; paged party receives ringback tone.
3. Paging station/attendant is connected to paged party.
Service Conditions
1. RADIO PAGING equipment is customer provided; refer to the manufacturer’s description for the
following specifications:
a.) types of tones
b.) capability of receiving individual radio numbers
c.) capability to call the addressed radio terminal 
d.) maximum number of stations that can be assigned individual radio access numbers.
2. A maximum of three digits can be assigned as access and answer codes.
3. The maximum number of digits assigned as individual radio numbers is three.
4. ATTENDANT CONSOLE [A-3] Attendants can activate this feature.
5. A station that has the CALL HOLD [C-6] feature activated cannot use RADIO PAGING.
6. The maximum number of RADIO PAGING answer zones is six.
7. The maximum number of routes that can be assigned RADIO PAGING is six.

R-16 Radio Paging
Service Conditions (cont’d)
8. If the paging user has failed to hang up within a predetermined, programmable time interval (after
activation), the paging connection is forcibly released.
9. If the paged party does not answer within 30 seconds, the NEAX2400 IMX will automatically page that
party again. If the paged party does not answer the second page within 30 seconds, the paging request will
be cancelled from memory. (See VARIABLE TIMING PARAMETERS [V-1]).
10. Both the COT card and the TLT card can be used as the paging trunk.
11. Loop signaling is the recommended signaling type.
12. 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.
13. 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 is provided the service.
b.) the restriction of route-to-route connection between FCCS nodes should be released.
14. 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.
15. A user can page one station at a time.
Interactions 
1. If the range of the radio page transmitter exceeds the physical limits of the PBX, an incoming C.O. call
acting as a response to a Radio Page cannot be connected in loop-to-loop procedures. The paging party
must disconnect, and the Attendant must extend the paged partys C. O. call.
2. RADIO PAGING and PAGING ACCESS [P-1] can be provided simultaneously in the same system.
Separate access codes for each feature are required. A RADIO PAGING answer code is required for each
Radio Paging zone. 
3. RADIO PAGING is limited to stations and Attendant Consoles. Other parties (C.O./TIE trunk calls) must
have the Attendant or user perform the paging operation.
4. The Attendant cannot dial the RADIO PAGING answer codes.
5. BUSY VERIFICATION [B-3], EXECUTIVE OVERRIDE [E-1]: These features will be denied when
connected to the Radio Paging route. 
6. Radio Page Answer will not follow any hunting on forwarding that the paging station has set.

R-49 Ringer Mute
R-49 Ringer Mute
General Description
This feature allows a user to stop ringing by pressing the associated feature key on the Dterm.
Operating Procedure
1. The Dterm user presses the RINGER MUTE key; the ringing is muted and the LED of the key lights. RING
OFF is displayed for three seconds.
2. The D
term user presses the RINGER MUTE key again; the ringing is recovered and the LED of the key is
turned off. RING ON is displayed for three seconds.
Service Conditions
1. The feature key for Ringer Mute must be assigned to the Dterm.
2. Ringer Mute which has been set becomes ineffective upon system initialization, individual initialization
of LP or initialization of PM.
3. While this service is activated, ringing for Call Back is not provided as well.
4. This service has no effect on the status of DO NOT DISTURB [D-11] service. For example:
