a Centrex line—for example, permitting all calls on a line at the extension where
it is assigned as a primary line while preventing outgoing calls on the line from
an extension where it is assigned as a secondary line. In addition, equipment
dialing restrictions can provide some of the protection provided by Centrex
restrictions, restricting dialing on a specific Centrex line assigned to an
extension, restricting dialing for all lines assigned to an extension, or overriding
equipment dialing restrictions. (Users can always place and receive intercom
calls, regardless of the equipment dialing restrictions placed on their
extensions.)
Refer to Table 4-5 on page 4-20 for a summary of the dialing restrictions and
permissions that are available through your equipment controller.
NOTE:
If you have Centrex dialing restrictions on a line and also program equipment
dialing restrictions for the line or an extension where the line is assigned, both
the Centrex and equipment restrictions will apply to the line or extension.
However, equipment dialing permissions will not override Centrex restrictions.
Restricting Line Access
As noted previously, Centrex dialing restrictions apply to all appearances of the
line to which they are assigned. If you wish to customize the restrictions for a
line that is assigned to more than one extension, use the System Programming
Line Access Restriction (#302) procedure to limit a particular extension’s
access to a Centrex line. For example, you may wish to set an extension’s
secondary lines to “incoming only.” This prevents the person at a covering
extension from making outgoing calls on another user’s primary line. The
following options are available for Line Access Restriction:
No restrictions. ■
Incoming only. The person at the extension can receive but not place ■
calls on the line. If you restrict a line on an extension to incoming calls
only, the user cannot get a dial tone on that line.
■ Outgoing only. The person at the extension cannot receive calls on the
line, but can place calls.
No access. The person at the extension can see the status of the line (by ■
looking at the lights next to the line button), join a call, and pick up a held
call. However, the user at the extension cannot place or receive calls on
the line.
For programming instructions for Line Access Restriction (#302), see page 5-11.
Restricting Dialing for All Lines at an Extension
The Line Access Restriction procedure controls an extension’s access to a line.
Once an extension has access to a line, what it can dial is controlled by
Outgoing Call Restriction, Disallowed Phone Number Lists, and (if a System
Password is defined) Night Service. These last three restrictions are similar to
those provided by Centrex; but the Centrex restrictions are by line (for all
extensions the line is assigned to) and the equipment restrictions are by
extension (for all lines assigned to the extension).
