Synchronous DS3 Add-Drop Multiplex (ADM 3/X) Requirements and Objectives

Document Number TR-TSY-000010
Issue Number 01
Issue Date Feb 1988

    ABSTRACT: This Technical Reference (TR) provides the view of Telcordia on appropriate generic technical requirements and objectives for the synchronous DS3 (44.736 Mbps) Add-Drop Multiplex (ADM 3/X).

    The ADM 3/X provides an interface between the Synchronous Transmission (SYNTRAN) DS3 signal and the DS1 signal. This document describes a version of the ADM 3/X that generates a SYNTRAN DS3 signal from up to 28 DS1 signals, and another version of the ADM 3/X that adds and drops several DS1 signals from an existing DS3 signal stream. ADM 3/X will be used in both the interoffice and distribution (loop) networks. A description of basic functions and features is also given.

    GR-449 and TR-TSY-000010 replaced TR-TSY-000021.
