ATM (Asynchronous Transfer Mode)

ATM Adaptation Layer AAL5 (ITU I.363.5)—Supports encapsulation and

de-encapsulation of AAL5 Protocol Data Units (PDUs) for

convergence. Segmentation and Reassembly (SAR) layer

segments and reassembles AAL5 PDUs into ATM cells that are

48 byte SAR-PDUs.

ATM Layer Attaches or strips the 5-byte header to the 48-byte SAR-PDU.

Cell Format Format complies with ITU I.361 ATM cell format. Cell delineation

complies with ITU I.432 Cell Delineation and HEC. Cells are fixed

length (53 bytes), including 5 bytes of header and 48 bytes of

payload. Included in the header are the VPI and VCI number.

Virtual Circuit type Permanent Virtual Circuit (PVC) per ATM forum UNI Version 3.1.

Maximum Virtual Circuits 32 virtual circuits that can simultaneously connect to service

providers for sessions encapsulated either as PPP or RFC 1483

Bridging/Routing.
