Replaces TR-NWT-001162 Issue01

    ABSTRACT: This document, GR-1162, replaces TR-NWT-001162, Issue 1 and Revision 1, but contains NO TECHNICAL CHANGES or data updates from that original document. It has been issued strictly to conform with the new Telcordia Technologies document format and carries a new issue number and date.

    This document contains the view of Telcordia on the Announcement Subsystem and Detection Subsystem requirements of the operator services system. The Announcement Subsystem provides information to operator services systems users (i.e., customers and Local Exchange Carrier [LEC] administrators) on an automated basis. The Detection Subsystem detects and decodes input in Dual-Tone Multifrequency (DTMF) or verbal form, tones generated by other operator services systems, post-seizure customer input, and user instructions. This document describes the system considerations, system architecture, system capabilities, system performance (i.e., the response time, availability, and redundancy requirements), and general transmission guidelines required of the Announcement Subsystem and Detection Subsystem. In addition, the types of announcements and evaluation of the Announcement Subsystem for intelligibility are discussed.

    When using GR-1162, you may need to refer to GR-1147. You may also want to refer to GR-506, GR-510, TR-TSY-000762, GR-1149, and/or GR-1175.
