Scope, Purpose, and Application

This document describes the operator services originating connection network capability, which permits the establishment and release of a network connection between a user and an operator service or services. This capability builds upon the existing basic call control procedures, defined in ANSI T1.113, for establishing and releasing connections.

A service invoking the operator services originating connection network capability may also invoke:

• User-Network Interaction network procedures (ANSI T1.113.4)

• Other network capabilities, e.g., Connection Hold (ANSI T1.666.4)

The transmission of information elements and related procedures defined in this document involve appropriate agreements between transmitting and receiving networks. These agreements are beyond the scope of this document.

This standard applies to the Integrated Services Digital Network (ISDN) User Part (ISUP) and is intended to supplement the signaling functions and call procedures described in ANSI T1.113. This standard could be used in conjunction with other American National Standards related to supplementary services and network capabilities. For a more complete understanding of the interactions between the Operator Services Originating Connection and other ANSI services and network capabilities, the appropriate American National Standards should be consulted.
