Glossary
A common bus at the rear of the HotWire 8600 DSLAM chassis connecting each DSL card
to the MCC card for diagnostic and network management. It also distributes dc power to
each slot.
The HotWire 8600 DSLAM chassis in a multi-system configuration (stack) that contains the
MCC card, which manages all of the DSL cards in the stack.
The physical building where the class 5 switch is located and the local telephone service
wiring is collected from a surrounding area.
The rack mounting that contains an interface panel, internal fan module, backplane and
three slots: one MCC card slot and two DSL card slots.
The rate at which data flows from the central office platform DSL port to the Remote
Terminal Units (RTUs).
Digital Subscriber Line.
Digital Subscriber Line Access Multiplexer.
A circuit card that contains DSL ports.
Electronic Industries Association.
A component in the chassis that cools the circuit cards in the chassis.
A plate that covers unused slots in the chassis. A slot that does not contain an MCC card
or DSL card must be covered by a filler plate.
The front panel of the Main Card. The – 48 Vdc terminal block, AC power connector (if
chassis has the AC power option), and interface connectors are accessible from this front
panel.
The TCP/IP standard protocol that defines the IP as a chassis of information passed
across an Internet and provides the basis for packet delivery service. IP includes the ICMP
control and error message protocol as an integral part. The entire protocol suite is often
referred to as TCP/IP because TCP and IP are the two most fundamental protocols.
Internet Protocol Address. A 32-bit address assigned to a host on a TCP/IP network. The
address has a host component and a network component.
Local Area Network.
Light-emitting diode. A light or status indicator on the chassis and the card faceplates that
glows in response to the presence of a certain condition (e.g., a fan alarm).
The set of variables a gateway running SNMP maintains. Standard, minimal MIBs have
been defined, and vendors often have private-enterprise MIBs. In theory, any SNMP
manager can talk to any SNMP agent with a properly defined MIB. MIB-II refers to an
extended management database that contains variables not shared by SNMP.
Management Communications Controller card. The MCC card is a powerful processor
card that works in conjunction with an SNMP network management system, such as DCE
Manager for HP OpenView, to gather operational status for each of the DSL cards in the
chassis (or stack).
MIB Release 2 is the current Internet-standard MIB.
