Hotwire 8620 and 8820 and GranDSLAM chassis. The operation and configuration

DSL Chassis
DSL cards can reside in four types of chassis:
8600/8610 DSLAM
A 3-slot chassis with Ethernet uplink. The stackable design provides for up to
six chassis to share management access through a single MCC card, wh ich in
turn allows an additional slot for a DSL card in each of up to five additional
chassis. The 8610 DSLAM chassis offers the same benefits as the
8600 chassis, with the added capability of accepting high-density DSL card s
(5–25 ports) such as the 8312 ReachDSL/MVL card. Management acce ss is
through the Management Communications Processor (MCP) card. For more
information, see either the

Hotwire 8600 Digital Subscriber Line Access

Multiplexer (DSLAM) Installation Guide

or the
