ABSTRACT:
THIS DOCUMENT IS SOLD ONLY AS AN
ENTERPRISE LICENSE
Automatic Callback (AC) is an outgoing CLASS feature that
allows a customer to automatically recall the last outgoing call. The customer
can request AC activation at any time after placing an outgoing call. The
busy/idle status of the calling and called lines is monitored, and call setup is
attempted when both calling and called lines are detected to be idle.
This Generic Requirements document (GR) defines the Telcordia view of generic
requirements for applications of AC for residential and small business
(non-Centrex) customers. The document provides the switching and signaling
system procedures to support this feature. Applications of this feature to
intra-Centrex calls are not addressed.
Issue 2 of this document incorporates changes to the feature interactions
between AC and Calling Name Delivery. The updated requirements were specified in
Bulletin 1, April 1995, and have also been incorporated into GR-1188-CORE,
Calling Name Delivery Generic Requirements.
This document is a module of LSSGR, FR-64 and was formerly TR-NWT-000215.
