Glossary

Ethernet	A type of network that supports high-speed communication among systems. It is a
	widely-implemented standard for LANs. All hosts are connected to a coaxial cable where
	they contend for network access using a Carrier Sense, Multiple Access with Collision
	Detection (CSMA/CD) paradigm.
Ethernet address	A six-part hexadecimal number in which a colon separates each part (for example,
	8:0:20:1:2f:0). This number identifies the Ethernet communications board installed in a PC
	and is used to identify the PC as a member of the network.
filter	A rule or set of rules applied to a specific interface to indicate whether a packet can be
	forwarded or discarded.
FTP	File Transfer Protocol. A TCP/IP standard protocol that allows a user on one host to
	access and transfer files to and from another host over a network, provided that the client
	supplies a login identifier and password to the server.
gateway address	The subnet that the end-user system is on.
GranDSLAM	A high-density DSLAM supporting a variety of DSL transport types and network services.
HDLC	High-Level Data Link Control. A communications protocol defined by the International
	Standards Organization (ISO).
host	A computer attached to a network that shares its information and devices with the rest of
	the network.
host route	An IP address having a subnet mask of 255.255.255.255.
ICMP	Internet Control Message Protocol. An Internet protocol that allows for the generation of
	error messages, test packets, and information messages related to IP.
Internet	The worldwide internetwork that predominantly uses the TCP/IP protocol.
intranet	A private network or internet using Internet standards and software, but protected from
	public access.
IP	Internet Protocol. An open networking protocol used for internet packet delivery.
IP address	Internet Protocol Address. The address assigned to an Internet host.
ISP	Internet Service Provider. A vendor who provides direct access to the Internet.
LAN	Local Area Network. A privately owned and administered data communications network
	limited to a small geographic area.
MAC	Media Access Control. The lower of the two sublayers of the data link layer, the MAC
	sublayer controls access to shared media.
MAC address	Media Access Control Address. The unique fixed address of a piece of hardware, normally
	set at the time of manufacture, and used in LAN protocols.
margin (DSL)	The additional noise, measured in dB, that would need to be added to the existing noise on
	a given DSL loop to bring the Bit Error Rate to IE–7 (107).
MCC Card	Management Communications Controller. The DSLAM circuit card used to configure and
	monitor the DSLAM.
MIB	Management Information Base. A database of managed objects used by SNMP to provide
	network management information and device control.
NAP	Network Access Provider. The provider of the physical network that permits connection of
	service subscribers to NSPs.
NMS	Network Management System. A computer system used for monitoring and controlling
	network devices.
