A proprietary network management program used with HP OpenView that helps a network
administrator manage SNMP devices.
A group of control and data characters that are switched as a unit within a communications
network.
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.
Plain Old Telephone Service. Standard telephone service over the PSTN with an analog
bandwidth of less than 4 Hz.
A device that filters out the DSL signal and allows the POTS frequencies to pass through.
Point-to-Point Protocol. A protocol for packet transmission over serial links, specified by
Internet RFC 1661.
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.
Remote Authentication Dial-In User Service. A user authentication protocol defined by
RFC 2058.
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.
A device that connects LANs by dynamically routing data according to destination and
available routes.
A table used by a node to route traffic to another node in the multiplexer network.
Remote Termination Unit. A DSL device installed at the customer premises.
Interface name of a DSL card’s DSL port #1.
Interface name of a DSL card’s DSL port #2.
Interface name of a DSL card’s DSL port #3.
Interface name of a DSL card’s DSL port #4.
Simple Network Management Protocol. Protocol for open networking management.
An application level program that facilitates communication between an SNMP
management system and a device. See NMS.
A message sent to an SNMP manager to notify it of an event, such as a device being
reset.
A user-specified permanent entry into the routing table that takes precedence over routes
chosen by dynamic routing protocols.
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.
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.
