Glossary

parameter

A numerical code that controls an aspect of terminal and/or network operation.

Parameters control such aspects as page size, data transmission speed, and

timing options.

permanent virtual circuit (PVC)

A frame relay logical link, whose endpoints and class of service are defined by

network management. Analogous to an X.25 permanent virtual circuit, a PVC

consists of the originating frame relay network element address, originating data

link control identifier, terminating frame relay network element address, and

termination data link control identifier. Originating refers to the access interface

form which the PVC is initiated. Terminating refers to the access interface at

which the PVC stops. Many data network customers require a PVC between two

points. Data terminating equipment with a need form continuous communion

use PVCs. See also data link connection identifier (DLCI).

ping

An internet protocol standard that provides loopback on demand for any device

in an IP network. One device "pings" another by sending a loopback request to

the device's IP address.

point-to-point

Type of communications link that connects a single device to another single

device, such as a remote terminal to a host computer.

RDL

Remote digital loopback.

remote configuration

A feature designed into ADTRAN DSU/CSU products that allow remote DSU/

CSU to be configured from a local DSU/CSU or VT100 compatible terminal.

router

A device that supports LAN-to-LAN communications. Routers may be equipped

to provide frame relay support to the LAN devices they serve. A frame-relay-

capable router encapsulates LAN frames in a frame relay frames and feeds those

frame relay frames to a frame relay switch for transmission across the network.

A frame-relay-capable router also receives frame relay frames from the network,

strips the frame relay frame off each frame to produce the original LAN frame,

and passes the LAN frame on to the end device. Routers connect multiple LAN
