A 10-Mbps Ethernet LAN that works on twisted-pair wiring.
A symbol (usually numeric) that identifies the interface attached to a network.
Address Resolution Protocol. Part of the TCP/IP suite, ARP dynamically links an IP
address with a physical hardware address.
A server whose function is to authenticate and log an end-user’s access location.
A common bus at the rear of a nest or chassis that provides communications and power to
circuit card slots.
The range of frequencies that can be passed by a transmission medium, or the range of
electrical frequencies a device is capable of handling.
Bootstrap Protocol. Described in RFCs951 and 1084, it is used for booting diskless nodes.
Bits per second. Bits per second. Indicates the speed at which bits are transmitted across
a data connection.
A sequence of successive bits (usually eight) handled as a unit in data transmission.
Carrierless Amplitude Modulation and Phase Modulation. A transmission technology for
implementing a Digital Subscriber Line (DSL). The transmit and receive signals are
modulated into two wide-frequency bands using passband modulation techniques.
CO. The PSTN facility that houses one or more switches serving local telephone
subscribers.
An identification used by an SNMP manager to grant an SNMP server access rights to
MIB.
The address used for routing packets whose destination is not in the routing table. In

addresses.
A system that detects and forwards DHCP discover or request messages to the
appropriate DHCP server.
A server which uses DHCP to allocate network addresses and deliver configuration
parameters to dynamically configured hosts.
A named group of machines on a network. In IP, a domain consists of a block of IP
addresses with similar prefixes.
In the direction of the customer premises.
Digital Subscriber Line. The non-loaded, local-loop copper connection between the
customer and the first node within the network.
Digital Subscriber Line Access Multiplexer. A platform for DSL modems that provides
high-speed data transmission with POTS over traditional twisted-pair wiring.
Name of the DSL card’s and MCC card’s 10BaseT (Ethernet) interface.
