Glossary
Backplane | 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. |
Base Chassis | The HotWire 8600 DSLAM chassis in a |
| MCC card, which manages all of the DSL cards in the stack. |
Central Office (CO) | The physical building where the class 5 switch is located and the local telephone service |
| wiring is collected from a surrounding area. |
Chassis | The rack mounting that contains an interface panel, internal fan module, backplane and |
| three slots: one MCC card slot and two DSL card slots. |
Downstream Data | The rate at which data flows from the central office platform DSL port to the Remote |
Rates | Terminal Units (RTUs). |
DSL | Digital Subscriber Line. |
DSLAM | Digital Subscriber Line Access Multiplexer. |
DSL Card | A circuit card that contains DSL ports. |
EIA | Electronic Industries Association. |
Fan Module | A component in the chassis that cools the circuit cards in the chassis. |
Filler Plate | 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. |
Interface Panel | 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. |
Internet Protocol (IP) | 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. |
IP Address | Internet Protocol Address. A |
| address has a host component and a network component. |
LAN | Local Area Network. |
LED | |
| glows in response to the presence of a certain condition (e.g., a fan alarm). |
Management | The set of variables a gateway running SNMP maintains. Standard, minimal MIBs have |
Information Base | been defined, and vendors often have |
(MIB) | manager can talk to any SNMP agent with a properly defined MIB. |
| extended management database that contains variables not shared by SNMP. |
MCC Card | 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 II | MIB Release 2 is the current |
