M-3 Miscellaneous Trunk Restriction
M-3 Miscellaneous Trunk Restriction
General Description
This feature provides for certain stations and certain dial-repeating TIE trunks to be denied access to particular trunk
groups, such as FX [F-2], WATS [W-1], CCSA [C-14], TIE LINE [T-3], Exchange Network, DICTATION [D-3]
or PAGING [P-1].
Operating Procedure
MISCELLANEOUS TRUNK RESTRICTION is accomplished via system data programming at the
MAINTENANCE ADMINISTRATION TERMINAL (MAT) [M-18].
Service Conditions
1. Restricted call attempts can be either: a.) intercepted by the Attendant,
b.) reorder tone can be initiated back to the originating user,
c.) user can be connected to an announcement informing the user of the re stricted call attempt, or
d.) prompted for Authorization Code.
2. Station line access to a given miscellaneous 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 TENANT [T-12],
each of which can be programmed to restrict an assigned station from none, one, or more than one
miscellaneous trunk group.
3. If the users class of service allows outgoing route completion via the ATTENDANT CONSOLE [A-3], the user can dial “0” to reach the Attendant for completion of miscellaneous tr unk calls.
4. The CALL TRANSFER - ALL CALLS [C-11] feature will operate as follows:  a.) if the restricted station is the controller, this station cannot add a trunk from which this station isrestricted. 
b.) if the restricted station line is not the controller, the controller cannot connect the restricted  station
line to a trunk from which the station is normally restricted.
5. 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 restricted stations.
6. NIGHT SERVICE [N-1, 2]: Restrictions can be changed for a given station when the system is switched to the Night mode of operation.
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
restricted station is denied dial access. If transfer is attempted, the controlling station is rung back.
8. TIE LINE ACCESS [T-3]: If the user accesses a TIE trunk at a distant PBX,  access to outside exchanges
can only be controlled by the distant PBX.

Multiple Console Operation M-4
M-4 Multiple Console Operation
General Description
This feature allows one or more ATTENDANT CONSOLEs [A-3] to operate within the same system.
Operating Procedure
No manual operation is required.
Service Conditions
1. The maximum number of consoles per PIM is 4.
2. The maximum number of consoles allowable per system is:
1 IMG: 16
4 IMG/IMX-U: 60
3. Each incoming call is displayed on an ATTENDANT CONSOLE [A-3], whether idle or busy. If all
Attendants are involved in processing calls when another Central Office call arrives, the CALL WAITING
LAMP [C-13] will light on all ATTENDANT CONSOLE [A-3]. This is a switched loop Attendant
operation.
4. If one of the ATTENDANT CONSOLE [A-3] enters the night mode, all calls addressed to the Attendant
will be directed to the other ATTENDANT CONSOLE [A-3]. However, the ATTENDANT CONSOLE
[A-3] that has entered the night mode must complete processing of all calls already connected to its loops.
5. A station can be connected to only one Attendant loop at a time. Any attempt at establishing multiple
connections will result in reorder tone being sent to the Attendant.
6. INTER-POSITION TRANSFER [I-5] is used to transfer calls between ATTENDANT CONSOLE [A-3].
7. Two methods of operation are available for placing the system (or tenant group) into the night mode:
a.) All ATTCON Change System Day to Night: When all ATTENDANT CONSOLE [A-3] press the
NITE key, the system (or associated TENANT [T-12]) enters the night mode. Night to Day:
When one ATTENDANT CONSOLE [A-3] releases the NITE key, the system (or associated
TENANT [T-12]) enters the day mode.
b.) Primary ATTCON Change System Day to Night: When the designated primary ATTENDANT
CONSOLE [A-3] presses the NITE key, the system (or associated TENANT [T-12]) enters the
night mode. If an ATTENDANT CONSOLE [A-3] other than the primary console presses the
NITE key, only that console enters the night mode. Night to Day: When the primary
ATTENDANT CONSOLE [A-3] releases the NITE key, the system (or associated TENANT [T-
12]) enters the day mode.
8. The automatic distribution of Attendant seeking calls is not provided (see Call Queuing). Any
ATTENDANT CONSOLE [A-3] assigned to the same tenant can answer a particular call; an exception is
an INTER - POSITION TRANSFER [I-5] directed call.
Interactions
1. See ATTENDANT CONSOLE [A-3] for information regarding a single Attendant Console and system
features provided to the Attendant Consoles. The Attendant Console must first be provided.
2. For each tenant, only one type of Attendant Console system can be assigned, either normal or Primary
Attendant Console system.
3. ASAT must be programmed for INTER-POSITION TRANSFER [I-5].

Music On Hold M-7
M-7 Music On Hold
General Description
This feature allows a party to hear music while in the CALL HOLD [C-6], CALL TRANSFER [C-10, 11], or
ATTENDANT CAMP-ON WITH TONE INDICATION [A-1] conditions.
Operating Procedure
No manual operation is required for this software controlled feature.
Service Conditions
1. The system is capable of supplying two switch-selectable music channels. Music is generated by 3
synthesizers included in the package.
2. If another music source (tuner, tape-deck, etc.) is desired, it must be customer provided.
3. Only one music source can be provided per system.
4. The held call condition can be the result of:
ATTENDANT CAMP-ON WITH TONE INDICATION [A-1] 
CALL HOLD [C-10]
CONSULTATION HOLD - ALL CALLS [C-17] 
SPLITTING [S-4] 
Attendant Hold
5. Only one music source, either customer-provided or internal, can be provided per system (system option).
6. ATTENDANT CONSOLE [A-3]: Attendant operations resulting in music to be provided to the calling
party include the following:
a.) The calling party or the remaining party (not talking with the Attendant) hears music, if the
Attendant splits a call prior to completion or after answering an Attendant recall.
b.) When incoming calls to the Attendant are answered and the Attendant presses the HOLD key, the
held party hears music. 
c.) When the Attendant camps on a call to a busy station, the calling party is connected to music until
the called party answers or the Attendant reenters the switched loop.
7. When a user in a two-party talking connection switch hook flashes, the second party is placed on hold and
is connected to music.
8. When activating this feature via the FCCS network, when either the internal or the external source is used,
it is recommended to set the source as the same MOH at each node for the node-to-node connection, since
the node that controls MOH varies depending on the connection pattern.
Interactions
1. Two types on MUSIC-ON-HOLD (MOH) exist; internal source MOH and external source MOH.
2. The input to the system is an 8-ohm output from the external music source. An 8-ohm music source is a
typical input to an 8-ohm speaker.
3. An external MOH source is connected to the EMA circuit card with 16 PH EXALM CA cable.
