Glossary
 Standard 1.1
application program interface
A set of routines, protocols, and tools that programmers use to develop software 
applications. APIs simplify the development process by providing commonly 
used programming procedures.
Asynchronous Transfer Mode
A network technology that uses start bits and stop bits (identifying the beginning 
and end of digital code) to facilitate data transfer. ATM equipment can transmit 
video, audio, and computer data over the same network, ensuring that no single 
type of data dominates the line.
Automatic Call Distribution (ACD) applications
A separate system or built-in feature of a PBX that equally distributes incoming 
calls to agents. As calls come in, they are placed into a queue (or a waiting line) 
for the next available agent. The RLC and its associated remote units support all 
of Nortel Networks’ ACD applications.
B  
bandwidth
The amount of data that the network can transmit, usually expressed in Mbytes 
per second. 
baseboard
See motherboard.
Basic Input/Output System
Flash ROM-based code that runs the Power-On Self-Test (POST) and bootstrap 
loader. BIOS contains low-level access routines for hardware that can be called 
from DOS.
basic rate interface
An ISDN subscriber service that uses two B (64Kbps) channels and one D (64 
Kbps) channel to transmit voice, video, and data signals.
