Glossary
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.
An authentication server can either be a RADIUS server or an XTACACS server and can
be used to confirm an end-user system’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
Routing Information Protocol (RIP), this is IP address 0.0.0.0.
Dynamic Host Configuration Protocol. A Microsoft protocol for dynamically allocating IP
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 block of IP addresses. Syntactically, all IP addresses within a given domain would share
a common IP address prefix of some length.
In the direction of the customer premises.
Digital Subscriber Line. DSL is a copper loop transmission technology enabling high-speed
access in the local loop.
Digital Subscriber Line Card. The primary card in the Hotwire DSLAM system. It has one
Ethernet port and four DSL ports.
Digital Subscriber Line Access Multiplexer. DSLAM provides simultaneous high-speed
digital data access and analog POTS over the same twisted-pair telephone line.
