T-7 Toll Restriction - 3/6-Digit
T-7 Toll Restriction - 3/6-Digit
General Description
This feature allows the NEAX2400 IPX 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 codes to be allowed or codes that are to be
denied.
2. This 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
[T-6] for further details.
4. The outgoing call using a trunk in the remote node via FCCS link is available. Therefore, Route Restriction
class data must be identical in the FCCS network. For more detailed information, see the NEAX2400 IPX
Fusion Network System Manual.
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 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.
7. When using the FCCS network, the outgoing call using a trunk in the remote node is available. Therefore,
Route Restriction class data must be identical in the FCCS network. For more detailed information, see
the NEAX2400 IPX Fusion Network System Manual.
