Operation is fully automatic that the 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
ADMINISTRATION TERMINAL (MAT) [M-18].
2.
Non-restricted stations within the system can CALL TRANSFER - ALL CALLS [C-11] outgoing
calls to the stations restricted by this feature.

Only the Attendant can permit the restricted stations to place outgoing calls via either of the
following features:

b.) NON-DELAY OPERATION
4.
Refer to CLASS OF SERVICE - INDIVIDUAL
15]
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 15 different RSCs (RSC1 - 15) per system, each
of which can be programmed to restrict an assigned station from none, one, or more than one
trunk group (maximum 31 trunk groups for the IMG (ICS) and IMGx; or 255 trunk groups for the
IMGxh, IMGdxh, MMG (ICS), UMG (ICS)).
6.
Two outgoing trunk group restriction tables are provided per system. The Direct Dial Access
table is indexed when a station 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 the restricted
stations.
7.
CALL TRANSFER - ALL CALLS [C-11]: If a restricted station 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 calling station is restricted from outgoing calls. If transfer is attempted, the
controlling station is rung back.
8.
TIE LINE ACCESS [T-3]: If the station user accesses a TIE trunk to a distant PBX, access to the
public exchange network can only be controlled by the distant PBX.
9.
THREE-WAY CALLING [T-2]: If a restricted station user calls another station, the called station
cannot add-on an outside exchange party via a trunk group in which the calling station is
restricted from outgoing calls. An attempt to add-on (SHF) will be ignored.
10. NIGHT SERVICE: Restrictions can be changed for a given station when the system is switched
to the night mode of operation.
