ABSTRACT: Call management services are a set of features that build on the capability to transport a calling party's number between end offices
with Common Channel Signaling (CCS) call setup messages. In addition, some call management services use non-circuit-associated messages
that allow a switching office to obtain intermission from another switching office, such as the busy/idle status of a line, without
setting as a call between the switching offices. CLASS (SM) Automatic Callback (AC), Automatic Recall (AR), and Screening List Editing
(SLE) are three examples of call management services.
This Generic Requirements (GR) document provides interconnecting CCS Networks (ICNs) with compatibility information required for
interconnecting with Local Exchange Carrier (LEC) networks for call management services. This document is a companion document to
GR-905, Common Channel Signaling (CCS) Network Interface Specification (CCSNIS) Supporting Network Interconnection, Message
Transfer Part (MTP) and Integrated Services Digital Network User Part (ISDNUP), and GR-1432, CCS Network Interface
Specification (CCSNIS) Supporting SCCP and TCAP, and supplements the basic information in them for call management services.
GR-1429 replaced TA-NWT-001429.
