Glossary
PHY
PHY as in physical specifications. OSI Physical Layer, which provides for transmission of
cells over a physical medium connecting two ATM devices.
ping
Packet InterNet Grouper. PING is a program used to test whether a particular network
destination on the Internet is online (i.e. working) by repeatedly bouncing a "signal" off a
specified address and seeing how long that signal takes to complete the round trip. No
return signal - site is down or unreachable. Portion is returned - trouble with the connection.
PLAR
Private Line, Automatic Ringdown. A leased voice circuit that connects two single
instruments together. When either handset is lifted, the other instrument automatically
rings.
PPP
Point-to-Point Protocol. is used for establishing a point-to-point link that provides a single,
preestablished WAN communications path from the customer premises, through a carrier
network (the telephone company), to a remote network
PPPoT1
Point-to-Point over T1.
PRACK
Provisionable acknowledgement.
Primary Rate Interface
(PRI)
The ISDN equivalent of a T1. The Primary Rate Interface (delivered to the customer’s
premise) provides 23B+D (N.America) or 30B+D (Europe) running at 1.544 Mb/sec and
2.048 Mb/sec, respectively.
protocol
Procedure or set of rules.
PVC
Permanent Virtual Circuit. A PVC is a permanent channel connection between two ATM
devices. PVC’s allow network transmissions to be started without having to first establish
a connection with the end point ATM device. When a PVC is constructed, the end points
of the connection will agree upon a path in which data will travel, and therefore agree upon
the route that data will travel to reach its destination.
Quality of Service (QoS)
The measure of the telephone service quality provided to a subscriber.
RADIUS
Remote Authentication Dial-In Service. RADIUS is a client/server-based authentication
software system. The software supports remote access applications, allowing an
organization to maintain user profiles in a centralized database residing on an
authentication server which can be shared by multiple remote access servers.
robbed bit
A type of analog signaling that will occasionally steal information bits used for circuit
signaling coding.
router
A computer or internet working device that directs traffic and moves packets between
networks. A hardware architecture used in LANs, MANs, WANs, the Internet and
Intranets. A device that connects any number of LANs. Routers use headers and a
forwarding table to determine where packets go, and they use ICMP to communicate with
each other and configure the best route between any two hosts.
