HotWire DSLAM Components
The HotWire DSLAM system consists of the following components:
HHotWire DSLAM chassis There are two types of chassis:
ÐEach 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.
