13 Glossary of Terms

Glossary

ARP –

Address Resolution Protocol –

allows devices to find a “host device” using the network layer (MAC

Address).

This allows SIP telephone endpoints to use non static IP Addresses when connecting to the

system

ACLEP –

Algebraic Code Excited Linear Predication –

Reproduces voice transmissions using

mathematical approximation that is determined 15ms prior to the next transmission, which itself is cal-
culating at 10 frames per second. This approximation allows for greater voice compression and signifi-
cantly better voice quality.

ATM –

Asynchronous Transfer Mode –

A packet switching transfer method designed to transport

real time voice and video over a standard telephone line.

Bridge –

A Cable or DSL modem/gateway is required to identify a specific location on their network.

Some ISP units incorporate a router so that the user does not have to purchase another device, while
others use a unit that has no routing capibility, and requires the user to supply a router. When using
remote workers or joining a voice network the ISP units must be set as a bridge, and the X-50 system
is used at the router.

BSS –

Basic Service Set –

.

BSSID –

Basic Service Set Identifier (BSSID) –

CHAP – Challenge Handshake Authentication Protocol –

similar to PAP but the ID and password

is encrypted.

CO –

Central Office –

A legacy telephone company line.

Converged –

A converged PBX is a system that can be used with both VoIP and PCM/TDM. The con-

verged system uses the PCM/TDM internally, while a Media Gateway (see Gateway) is used to integrate
the Voice over IP component.

Default Gateway –

The default gateway, usually seen as an IP Address, is the location used for end-

points to access the Internet, sometimes called the “Doorway to the Internet”. If the default gateway is
not entered or entered incorrectly, endpoints will have no access to the Internet.
