Miscellaneous Trunk Restriction - PRI
General Description
This feature provides for incoming PRI trunks to be denied access to particular 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 reorder tone can be initiated back 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, thus allowing
Attendant completion of outgoing calls for restricted stations.
4.
CALL TRANSFER - ALL CALLS - PRI [C-99]: 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.
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.
