Glossary

NMS	Network Management System. A computer system used for monitoring and controlling
	network devices.
NSP	Network Service Provider. A local telephone company or ISP that provides network
	services to subscribers.
packet	A group of control and data characters that are switched as a unit within a communications
	network.
PING	An IP-based application used to test reachability of destinations by sending an ICMP echo
	request and waiting for a reply. The ping program is supported from both the DSL and
	MCC cards.
POTS	Plain Old Telephone Service. Standard telephone service over the PSTN with an analog
	bandwidth of less than 4 Hz.
POTS Splitter	A device that filters out the DSL signal and allows the POTS frequencies to pass through.
PPP	Point-to-Point Protocol. as specified by Internet RFC 1661.
proxy ARP	Proxy Address Resolution Protocol (ARP). A technique for using a single IP address for
	multiple networks. A device responds to ARP requests with its own physical address, then
	routes packets to the proper recipients.
Router	A device that connects LANs by dynamically routing data according to destination and
	available routes.
Routing Table	A table used by a node to route traffic to another node in the multiplexer network.
RTU	Remote Termination Unit. A DSL device installed at the customer premises.
s1c	Interface name of a DSL card's DSL port #1.
s1d	Interface name of a DSL card's DSL port #2.
s1e	Interface name of a DSL card's DSL port #3.
s1f	Interface name of a DSL card's DSL port #4.
Service Node	Endpoint modem at the customer premise, also known as a Remote Termination Unit
	(RTU). There are two model types. See RADSL and MVL.
SNMP	Simple Network Management Protocol. Protocol for open networking management.
SNMP agent	An application level program that facilitates communication between an SNMP
	management system and a device. See NMS.
SNMP trap	A message sent to an SNMP manager to notify it of an event, such as a device being
	reset.
static route	A user-specified permanent entry into the routing table that takes precedence over routes
	chosen by dynamic routing protocols.
subnet address	The subnet portion of an IP address. In a subnetted network, the host portion of an IP
	address is split into a subnet portion and a host portion using an address (subnet) mask.
	This allows a site to use a single IP network address for multiple physical networks.
subnet mask	A number that identifies the subnet portion of a network address. The subnet mask is a
	32-bit Internet address written in dotted-decimal notation with all the 1s in the network and
	subnet portions of the address.
TCP	Transmission Control Protocol. An Internet standard transport layer protocol defined in
	STD 7, RFC 793. It is connection-oriented and stream-oriented.
