Glossary

10BaseT	A 10-Mbps Ethernet LAN that works on twisted-pair wiring.
address	A symbol (usually numeric) that identifies the interface attached to a network.
ARP	Address Resolution Protocol. Part of the TCP/IP suite, ARP dynamically links an IP
	address with a physical hardware address.
authentication server	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.
backplane	A common bus at the rear of a nest or chassis that provides communications and power to
	circuit card slots.
bandwidth	The range of frequencies that can be passed by a transmission medium, or the range of
	electrical frequencies a device is capable of handling.
BootP	Bootstrap Protocol. Described in RFCs951 and 1084, it is used for booting diskless nodes.
bps	Bits per second. Bits per second. Indicates the speed at which bits are transmitted across
	a data connection.
byte	A sequence of successive bits (usually eight) handled as a unit in data transmission.
CAP	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.
central office	CO. The PSTN facility that houses one or more switches serving local telephone
	subscribers.
Community name	An identification used by an SNMP manager to grant an SNMP server access rights to
	MIB.
default route	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.
DHCP	Dynamic Host Configuration Protocol. A Microsoft protocol for dynamically allocating IP
	addresses.
DHCP Relay Agent	A system that detects and forwards DHCP discover or request messages to the
	appropriate DHCP server.
DHCP Server	A server which uses DHCP to allocate network addresses and deliver configuration
	parameters to dynamically configured hosts.
domain	A block of IP addresses. Syntactically, all IP addresses within a given domain would share
	a common IP address prefix of some length.
downstream	In the direction of the customer premises.
DSL	Digital Subscriber Line. DSL is a copper loop transmission technology enabling high-speed
	access in the local loop.
DSL card	Digital Subscriber Line Card. The primary card in the Hotwire DSLAM system. It has one
	Ethernet port and four DSL ports.
DSLAM	Digital Subscriber Line Access Multiplexer. DSLAM provides simultaneous high-speed
	digital data access and analog POTS over the same twisted-pair telephone line.
