The 8610 DSLAM accepts the following types of cards:
HManagement Control Processor (MCP). This 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.
HMVL, RADSL and DSL cards. These cards provide a processor and an Ethernet
interface to the NSP. The processor controls the modems and forwards the packet
traffic to and from the Ethernet and DSL interfaces. Models include:
— 8310 4-port and 8312 12-port Multiple Virtual Lines (MVL) cards that
interoperate with the Hotwire 6310 modem.
— 8510 Rate Adaptive Digital Subscriber Line (RADSL) card that interoperates
with the 5620 Remote Termination Unit (RTU).
— 8540 Digital Subscriber Line (DSL) card that interoperates with either the 5216
or 5246 Remote Termination Unit (RTU).
— 8546 DSL card that interoperates with the 5446 RTU.
HMultirate High-bit-rate Digital Subscriber Line (M/HDSL) card.
HMultirate Symmetric Digital Subscriber Line (M/SDSL) card.
NOTE:
RADSL, MVL, M/HDSL and M/SDSL cards are generically referred to as DSL
cards in this document.
Hotwire 8610 DSLAM Features
The Hotwire 8610 DSLAM chassis has the following features:
HPower Redundancy
Two versions of the Hotwire 8610 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.
