ATM adaptation layer

ASYNCHRONOUS TRANSFER MODE NETWORKING TECHNOLOGY

AAL3; AAL4; AAL3/4; AAL (ATM Adaptation Layer); ATM Adaptation Layers; ATM Adaptation Layer; AAL0

The use of Asynchronous Transfer Mode (ATM) technology and services creates the need for an adaptation layer in order to support information transfer protocols, which are not based on ATM. This adaptation layer defines how to segment higher-layer packets into cells and the reassembly of these packets.

ATM Adaptation Layer 5

ATM ADAPTATION LAYER

AAL5

ATM Adaptation Layer 5 (AAL5) is an ATM adaptation layer used to send variable-length packets up to 65,535 octets in size across an Asynchronous Transfer Mode (ATM) network.

ATM Adaptation Layer 2

ATM ADAPTATION LAYER

Aal2; AAL2; AAL Type 2; A2EA (AAL type 2 Service Endpoint Addresses); A2EA

ATM Adaptation Layer 2 (AAL2) is an Asynchronous Transfer Mode (ATM) adaptation layer, used primarily in telecommunications; for example, it is used for the Iu interfaces in the Universal Mobile Telecommunications System, and is also used for transporting digital voice. The standard specifications related to AAL2 are ITU standards I.
