HotWire DSLAM Chassis
There are two types of chassis:
 HotWire 8600 DSLAM chassis
The HotWire 8600 DSLAM is a low-cost alternative to the HotWire
8800 DSLAM. Each 8600 DSLAM chassis is an independent, stand-alone
system. A stackable design provides for six systems 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 systems. In a stacked configuration, the first
or base chassis is equipped with an MCC card in Slot 1, leaving Slots 2 and 3
available for up to two DSL cards or a maximum of eight DSL ports. Each
additional chassis houses up to three DSL cards. This stacking capability
allows you to incrementally expand your DSL access service.
