About the HotWire 8600 DSLAM

HotWire 8600 DSLAM Features
The HotWire 8600 DSLAM system has the following features:
H Power Redundancy
Two versions of the HotWire 8600 DSLAM chassis are available:
— ac power
— dc power
The ac version can also be connected to a dc source to provide power
redundancy. When using the dc version, two separate dc sources may be
employed to provide power redundancy. If one power source fails, the other
source provides all of the power needed by the system. This is done
automatically without system disruption.
The dc version requires a source of – 48 Vdc, while the ac version will
operate from 100 to 250 volts ac, 50 to 60 Hz.
H
Front-Facing Interface Connections
The interface connections on the front of the chassis allows all interface
cables to be connected and maintained in the front of the chassis for easy
accessibility.
H
Stackable Chassis for DSL Access Growth
Each chassis is an independent, standalone system. The 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 additional 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 system will accept up to three DSL cards for a maximum of
12 additional DSL ports.
A HotWire 8600 DSLAM chassis can be added or removed from the stack
without disrupting service to the other items in the stack.
The base system is electrically connected to additional systems by
connecting the 8-pin modular expansion cable provided from the OUT port of
the base chassis to the IN port of the next chassis in the stack.
H Hot Swappable Cards
The MCC and DSL cards can be installed and removed from the HotWire
8600 DSLAM chassis without service disruption. You can replace a card
without powering down the chassis and disrupting service to the other cards.
H
Primary Network Management Support via SNMP
SNMP management of the DSL cards is accomplished over a single Ethernet
connection to the MCC card from a Network Management System (NMS)
(such as Paradyne’s DCE Manager for HP OpenView). The MCC card
gathers all management information for each of the DSL cards and responds
to the SNMP requests on behalf of the cards.
For a list of specific management information bases (MIBs) supported, see
the HotWire DSLAM for 8540 and 8546 DSL Cards Network Configuration
Guide.
