162 Access Restrictions
Access Restrictions are applied through service change overlay programs.
Access to telephone and trunk features is denied in the respective data
block by allowing the system to default to a denial, by not entering the
appropriate feature code, or by not assigning the feature to a key/lamp
pair. You must enable the features and Access Restrictions you want, on a
customer and telephone level.
Services such as paging and dictation can be restricted through TGAR
codes, because the auxiliary equipment is linked to the system by way of
trunks.
Feature interactions
AC15 Recall: Timed Reminder Recall
With call modification, a trunk-to-trunk connection is controlled by signaling,
recall capability and the supervision assigned to each trunk. For example,
an established call from an unsupervised trunk cannot be transferred over
another trunk.
When the AC15 Timed Reminder Recall feature is to be activated, an
established call with an unsupervised trunk may be extended over an AC15
trunk because the connection is controlled before the called party answers
by the AC15 recall timer.
Call Park
A call can be parked on any DN, regardless of its Class of Service. Access
to a parked call is governed by the same Class of Service restrictions
for normal trunk-to-telephone call processing. Table
Table 4 "Parked call
Access Restrictions." (page 162) details the restrictions. These restrictions
can be overridden with the Authorization Code.
