SCM Card
The Shelf Concentration Module (SCM) card aggregates DSL traffic for the
Hotwire 8620 and 8820 and GranDSLAM chassis. The operation and configuration
of this card is not within the scope of this document. See the
Hotwire Shelf
Concentration Module (SCM) Card User’s Guide
for more information.
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, which 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 cards
(5–25 ports) such as the 8312 ReachDSL/MVL card. Management access 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
Hotwire 8610 DSLAM
Installation Guide
