HotWire 8800 DSLAM Components
The HotWire 8800 DSLAM system consists of the following components:
HotWire 8800 DSLAM chassis
HotWire 8800 is a 20-slot chassis with integral power, alarm, cooling, and
interface subsystems designed to house up to 18 DSL cards and one
Management Communications Controller (MCC) card. (The remaining slot is
reserved for future use.)
One Management Communications Controller (MCC) card
The chassis requires one MCC card, which is a processor card that
administers and provides diagnostic connectivity to the DSL cards. It acts as
a mid-level manager and works in conjunction with an SNMP network
management system, such as HP OpenView, via its LAN port. It gathers
operational status for each of the DSL cards and responds to the SNMP
requests. It also has a serial port for local terminal access.
At least one Digital Subscriber Line (DSL) card
The chassis requires at least one DSL card, which is a circuit card that
contains four DSL ports, an Ethernet interface to the NSP, and a processor.
The processor controls the modems and forwards the packet traffic to and
from the Ethernet and DSL interfaces. When the chassis is fully populated, it
provides a total of 72 DSL ports.
NOTE:
You must order the MCC and DSL cards separately. They are not provided
with the chassis.
