MISCELLANEOUS TRUNK RESTRICTION
GENERAL DESCRIPTION
This service feature provides for certain stations and certain dial-repeating Tie trunks to be denied
access to particular trunk groups such as Tie Line, Exchange Network, DICTATION ACCESS or PAGING
ACCESS.
STATION APPLICATION
Not applicable
OPERATING PROCEDURE
MISCELLANEOUS TRUNK RESTRICTION is accomplished via system data programming at the
MAINTENANCE ADMINISTRATION TERMINAL (MAT) and CUSTOMER ADMINISTRATION
TERMINAL (CAT).
SERVICE CONDITIONS
1. Restricted call attempts will receive Reorder Tone.
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 8 different RSCs per system, each of which can
be programmed to restrict an assigned station for none, one, or more than one miscellaneous trunk
group.
3. This feature can be applied to stations via CLASS OF SERVICE restrictions.
4. If the station user’s CLASS OF SERVICE allows outgoing route completion via the Attendant, the sta-
tion user can dial “9” to reach the Attendant for completion of miscellaneous trunk calls.
5. The CALL TRANSFER - ALL CALLS feature will operate as follows:
a. If the restricted station line is the controller, this station cannot add a trunk from which this station
is restricted.
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.
c. This feature can be applied to dial repeating trunks via route to route restrictions.
6. Night Service: Restrictions can be changed for a given station when the system is switched to the night
mode of operation.
7. CALL TRANSFER - ALL CALLS: If a restricted station 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: If the station user accesses a tie trunk to a distant PBX, access to outside exchanges
can only be controlled by the distant PBX.
