About This Guide

Document Purpose and Intended Audience

This guide describes how to:

Mount the HotWire 8600 Digital Subscriber Line Access Multiplexer (DSLAM)
chassis in a rack

Stack two to three chassis on a tabletop or desktop

Install the Management Communications Controller (MCC) card

Install the Digital Subscriber Line (DSL) cards

Make cable connections to the CO POTS (Plain Old Telephone Service)
Splitter, MDF, or other demarcation point

Make cable connection to a network management system (NMS), such as a
Simple Network Management Protocol (SNMP) management system

Connect the DSL cards to the Ethernet hubs and switches

Make cable connection to a console, computer, or modem

It is written for administrators and technicians who install devices at the Central
Office (CO) or at an Internet Service Provider (ISP) location adjacent to the CO.

A HotWire 8600 DSLAM system requires an MCC card and at least one DSL
card. Multiple 8600 DSLAMs can share management connectivity through an
MCC card in a single 8600 DSLAM. These additional systems house up to three
DSL cards. It is assumed that you have already purchased the required circuit
cards.

To install the Customer Premises (CP) portion of the HotWire 8600 DSLAM, refer
to the 

appropriate HotWire Remote Termination Unit (RTU) Customer Premises

Installation Instructions and HotWire POTS Splitter Customer Premises
Installation Instructions.
