MCC Card
The MCC card is a single resource in the Hotwire DSLAM that provides
consolidated management access for the DSL cards and the Hotwire RTU from
any one of the following:
H SNMP management systems, such as HP OpenView with Paradyne’s
OpenLanet DCE Manager (via the MCC card’s Ethernet port),
H Remote telnet sessions (via the MCC card’s Ethernet port),
H Local asynchronous terminal (via the MCC card’s VT100 serial port), or
H Remote asynchronous terminal connected to a modem (via the MCC card’s
serial port).
The MCC card performs alarm monitoring of the Hotwire DSL cards, the DSLAM
power and cooling systems, and interfaces to the CO alarm system. It also
interfaces with external managers and servers (e.g., Trivial File Transfer Protocol
servers) for system configuration and management.
DSL Cards
Each 8540 or 8546 DSL card in the Hotwire DSLAM chassis contains four DSL
ports with on-board IP packet forwarding functionality. The outputs of the four
DSL ports are combined onto one 10BaseT interface for connecting to the
Internet or Intranet by means of the Network Access Provider’s network.
For a list of the supported features of the 8540 and 8546 DSL cards, see the
Hotwire DSLAM for 8540 and 8546 DSL Cards User’s Guide

What is an RTU?
A Hotwire Remote Termination Unit (RTU) resides at the customer premises. The
RTU connects to the local loop to provide high-speed connectivity to the Hotwire
DSLAM. In addition, the RTU and your telephone can function simultaneously
over the same pair of copper wires when a POTS splitter is used at both ends of
the local loop. The POTS splitter filters out the DSL signal and allows the POTS
frequencies to pass through.
