T-7
General Description
This feature allows the PBX to be programmed to restrict outgoing calls according to specific area and/or
central office codes. This restriction is controlled on the basis of a three-digit area code or a six-digit
combination area and office code numbering plan.
Operating Procedure
No manual operation is required.
Service Conditions
1.
The programmed restriction pattern may consist of either those codes to be allowed or those
codes that are to be denied.
2.
The TOLL RESTRICTION-3/6 DIGIT feature is assigned on a CLASS OF SERVICE-
INDIVIDUAL [C-15] basis.
3.
When a toll call is denied, Reorder Tone will be returned to the calling party. If desired, the calling
party can be routed to the Attendant Console. See TOLL DENIAL/TOLL DIVERSION
further details.
Interactions
1.
When Toll Restriction is specified in ARRC, all the possible dialing-patterns must be assigned in
ATDP. If office codes within an Area Code do not need to be restricted, allow the Area Code only.
Always provide the system with the most economical configuration of digits when constructing
TOLL RESTRICTION tables.
2.
In the ARRC command, ARI-A-RES must be programmed to allow two trunks and a station in a
conference. ARI-D-RES is programmed if the two trunks are to remain connected after the
station drops off, or if TOLL RESTRICTION applies to a direct trunk-to-trunk connection, such
as, TIE Line to DDD.
3.
ROUTE ADVANCE [R-6]: Station A dials a toll call by accessing route 1. Route 1 is busy and
advances to route 2. Station A is restricted from making this call on route 2. The call will be
restricted.
4.
PASSING DIAL TONE [P-2]: The Attendant cannot use PASSING DIAL TONE [P-2] to allow a
toll-restricted station from using a restricted route.
5.
OUTGOING TRUNK QUEUING [O-2]: When a station is restricted from all other routes, a station
user may queue a trunk to complete a call over unrestricted routes.
6.
LEAST-COST ROUTING-3/6-DIGIT [L-5]: Translations in AFRS must be such that the digits
dialed in the trunk-to-trunk connection would be recognizable in terms of choosing a route. If a
route cannot be chosen, TOLL RESTRICTION 3/6 DIGIT cannot be applied.
