HotWire DSLAM Components
The HotWire DSLAM system consists of the following components:
HotWire DSLAM chassis
There are two types of chassis:
— Each HotWire 8600 DSLAM is an independent, standalone system. The
stackable design provides for up to six systems to share management
access through a single Management Communications Controller (MCC)
card, which in turn, allows an additional slot for a DSL card in each of up
to five additional systems.
In a stacked configuration, the first, or base chassis, must contain an
MCC card in Slot 1. In addition to the MCC card, the base chassis can
house up to two DSL cards. Each additional chassis in the stack houses
up to three DSL cards.
