Chapter 6: System planning and engineering

Overview

Purpose

This section summarizes basic system planning and engineering information to plan procurement and deployment of Alcatel-Lucent 1665 Data Multiplexer (Alcatel-Lucent 1665 DMX).

There are a number of considerations that should be kept in mind when planning the Alcatel-Lucent 1665 DMX's role in the network. Projected customer requirements will determine initial capacity needed, as well as evolution to higher capacities. The advanced networking capabilities of the Alcatel-Lucent 1665 DMX offer many economic and planning benefits, and certain guidelines should be followed to maximize these benefits. Physical installation considerations will be guided by the installation location (central office, uncontrolled, or customer locations). Initial network configuration will determine synchronization requirements. Synchronization should be planned on a network basis considering items like topology, reliability, internetwork connectivity, and service evolution.
