Enterprise Edge Programming Operations Guide P0911588 Issue 01

A packet-switching scheme is an efficient way to handle transmissions on a

connectionless network such as the Internet. An alternative scheme,

circuit-switching, is used for networks allocated for voice connections. In

circuit-switching, lines in the network are shared among many users as with

packet-switching, but each connection requires the dedication of a particular path

for the duration of the connection.

Packet and datagram are similar in meaning. A protocol similar to TCP, the User

Datagram Protocol (UDP) uses the term datagram.

Page

A feature you can use to make announcements over the Enterprise Edge system.

You can make page announcements over the telephone speakers and/or external

speakers.

Page Time out

A setting that controls how long a Page Announcement can last. It can be assigned

under Feature settings in System programming.

Page zone

An area in the office that receives internal page announcements independently of

the rest of the office.

Each page zone is identified by a number. Telephones are assigned to page zones

under Capabilities in Terminals and Sets programming.

PAP

The Password Authentication Protocol (PAP) is a procedure used by PPP servers to

validate a connection request. PAP works as follows:

1. After the link is established, the requestor sends a password and an id to the

server.

2. The server either validates the request and sends back an acknowledgement,

terminates the connection, or offers the requestor another chance.

Passwords are sent without security and the originator can make repeated attempts

to gain access. For these reasons, a server that supports CHAP will offer to use that

protocol before using PAP.

Parallel port

A port that transfers data through multiple wires so that eight bits are transmitted

simultaneously. Parallel ports usually use a 25-pin interface that transmits and

receives data one byte at a time using a separate data line for each bit.

Park prefix

See Call park prefix.
