126 AC15 Recall: Timed Reminder Recall
Night Service must be activated, the original call must be an external call,
and International Supplementary Features (SUPP) package 131 equipped
for a call to be recalled to the Night DN. That is the only situation where an
AC15 recall will not be presented to the attendant.
Answer supervision must be configured on the AC15 TIE trunk for the
feature to be activated.
XFEM trunk cards that support AC15 signaling are required (for example,
the NT5K19AC trunk card for the UK).
Feature interactions
AC15 Recall: Transfer from Norstar
A transfer performed by an AC15 trunk using the Transfer from Norstar
feature to another AC15 trunk is not subject to Timed Reminder Recall.
This is to prevent a call transferred by someone on Norstar from recalling
the system attendant.
It is recommended that all AC15 cards on the network’s system are
NT5K19AC or later. This is mandatory for the system which directly
interfaces with the Norstar (this requirement applies to all of this switch’s
AC15 cards, even to those that do not directly interface with the Norstar).
Access Restrictions
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.
Attendant Clearing During Night Service (ACNS)
If ACNS is active and there is a call being extended over an AC15 TIE trunk,
when the attendant goes into Night Service, the transfer is completed and
the feature is activated.
If there is an AC15 recall presented to the attendant and it goes in Night
Service, the recall is put in the attendant queue.
If an AC15 recall has been answered by the attendant and it goes in Night
Service, the call is removed from the attendant port and the feature is
activated again.
