Hotwire DSL System Description

HThe Hotwire 8820 GranDSLAM is a 20-slot chassis with integral power, alarm, cooling, and interface subsystems designed to house up to 17 DSL cards, as well as an SCM card for aggregating DSL traffic to an ATM uplink and an MCP card. Layer 3 systems do not use SCM card functionality. Also for Layer 3 systems, the 8820 GranDSLAM houses 8546 cards only, not 8540 cards. For more information, see the Hotwire GranDSLAM Installation Guide.
