Access transport for voice and TDM Private Line services

Overview

Alcatel-Lucent 1665 DMX supports a full set of interfaces, topologies, and operations to provide the flexibility, upgradability, and ease of operation required to meet the dynamic requirements of the access transport environment. An Alcatel-Lucent 1665 DMX OC-12/48/192 path switched ring for TDM transport of voice and Private Line services is a reliable infrastructure for residential or small business voice services.

Description

Alcatel-Lucent 1665 DMX is particularly suited to the evolving needs of voice and Private Line access transport applications due to its compact size, environmental hardening, and capacity growth potential. Alcatel-Lucent 1665 DMX 's flexibility allows the infrastructure to be optimized for a particular fiber topology, service mix, and growth forecast. Alcatel-Lucent 1665 DMX can simultaneously support wideband and broadband Private Line services for DS1, DS3, E1, EC-1, OC-3, OC-12, and OC-48 client interfaces.

The figure below shows a path switched ring transporting low-speed DS1 signals that are carrying voice services from a PBX or a digital loop carrier (DLC) system over an OC-48 or OC-192 ring. In this application, Alcatel-Lucent 1665 DMX hands off these voice circuits to the voice switch in the central office using a very cost-effective DS1/EC-1 interface.
