NOTES:
— All references to DSL cards in this document refer to the RADSL, MVL,
ReachDSL, IDSL, and SDSL cards, unless specifically noted otherwise.
The ATM and TDM SDSL line cards are not within the scope of this
document.
— The 8312/8314 ReachDSL v1 cards appear on the screen with their
former MVL name.
SCM Card
The Shelf Concentration Module (SCM) card aggregates DSL traffic for the
Hotwire 8620 and 8820 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– 24 ports) such as the 8343 SDSL 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
.
