RESTRICTION FROM OUTGOING CALLS
GENERAL DESCRIPTION
This service feature automatically denies preselected station lines within the system the ability to place
outgoing calls and/or certain miscellaneous trunk calls without Attendant assistance.
STATION APPLICATION
All stations
OPERATING PROCEDURE
Operation is fully automatic in that restricted stations will receive Reorder Tone upon attempting to place a
restricted call.
SERVICE CONDITIONS
1. This feature is programmable via system data programming from the MAINTENANCE ADMINIS-
TRATION TERMINAL (MAT) or CUSTOMER ADMINISTRATION TERMINAL (CAT).
2. Non-restricted stations within the system can transfer outgoing calls using to restricted stations CALL
TRANSFER - ALL CALLS.
3. Only the Attendant can permit restricted stations to place outgoing calls via either of the following fea-
tures:
a. PASSING DIAL TONE
b. NON-DELAY OPERATION
4. Refer to CLASS OF SERVICE - INDIVIDUAL and DAY/NIGHT CLASS OF SERVICE for further
details.
5. Station line access to a given 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 from none, one, or more than one trunk group (maximum 64 trunk
groups).
6. When a trunk group access code is dialled, the station user’s assigned RSC is used to index a trunk
group (route) restriction table to determine if the call attempt is allowed.
7. CALL TRANSFER - ALL CALLS: If a restricted station user calls another station, the called station
cannot use the CALL TRANSFER - ALL CALLS to connect the calling station to a trunk group which
dial access from the restricted station is denied. If the transfer is attempted, the controlling station is
rung back.
a. 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.
b. THREE-WAY CALLING: If a restricted station user calls another station, the called station can-
not add-on an outside exchange party via a trunk group which the dial access from the restricted
station is denied. An attempt add-on (SHF) will result in a split connection.
c. NIGHT SERVICE: Restrictions can be changed for a given station when the system is switched to
the night mode of operation.
