Miscellaneous Trunk Restriction - PRI M-72
M-72 Miscellaneous Trunk Restriction - PRIGeneral Description
This feature provides for incoming PRI trunks to be denied access to particula r trunk groups such as FX ACCESS
[F-2], WATS ACCESS [W-1], CCSA ACCESS [C-14], TIE LINE ACCESS [T-3], exchange network, or PAGING
ACCESS [P-1].
Operating Procedure
MISCELLANEOUS TRUNK RESTRICTION - PRI is accomplished via system data programming at the
MAINTENANCE ADMINISTRATION TERMINAL (MAT) [M-18].
Service Conditions
1. Restricted call attempts can be either intercepted by the Attendant , or re ord er ton e can be init ia ted ba ck to
the originating user.
2. The CALL TRANSFER - ALL CALLS [C-11] feature operates as follows:
a.) If the restricted station is the controller, the 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.
3. 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, th u s allow ing
Attendant completion of outgoing calls for restricted stations.
4. CALL TRANSFER - ALL CALLS - PRI [C-99]: If a restricted user calls another st ation, the called sta tion
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.
5. 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.
