Glossary

NSP	Network Service Provider. A local telephone company or ISP that provides network
	services to subscribers.
OpenLane DCE	A proprietary network management program used with HP OpenView that helps a network
Manager	administrator manage SNMP devices.
packet	A group of control and data characters that are switched as a unit within a communications
	network.
PING	Packet InterNet Groper. A program that is useful for testing and debugging networks. It
	sends an Echo packet to the specified host, and waits for a response. It reports success or
	failure and statistics about its operation.
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. A protocol for packet transmission over serial links, 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.
RADIUS	Remote Authentication Dial-In User Service. A user authentication protocol defined by
	RFC 2058.
RADSL	Rate Adaptive Digital Subscriber Line. A technique for the use of an existing twisted-pair
	line that permits simultaneous POTS and high-speed data communication at adaptive
	symmetric and asymmetric rates.
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.
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.
