ADPCM

Adaptive Differential Pulse Code Modulation: A reduced bit rate variant of PCM audio encoding (see also PCM). This algorithm encodes the difference between an actual audio sample amplitude and a predicted amplitude and adapts the resolution based on recent differential values.

ADTF

ACR Decrease Time Factor: This is the time permitted between sending RM-cells before the rate is decreased to ICR (Initial Cell Rate). The ADTF range is 0.01 to 10.23 sec. with granularity of 10 ms.

AFI

Authority and Format Identifier: This identifier is part of the network level address header.

Agent

Acts on behalf of another person or thing, with delegated authority. The agents goals are those of the entity that created it.

Aggregation Token

A number assigned to an outside link by the border nodes at the ends of the outside link. The same number is associated with all uplinks and induced uplinks associated with the outside link. In the parent and all higher-level peer group, all uplinks with the same aggregation token are aggregated.

AHFG

ATM-attached Host Functional Group: The group of functions performed by an ATM-attached host that is participating in the MPOA service.

AI

Artificial Intelligence: Perhaps the next phase of computing. The present form of IA in computer software are called Expert or Knowledge Based systems.

AI

Signaling ID assigned by Exchange A.

AIM

ATM Inverse Multiplexer: A term discontinued because of conflict with an established product. Refer to AIMUX.
