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.
Attaches or strips the 5-byte header to the 48-byte SAR-PDU.
Performance is a maximum line rate of 17,812 cells per second
downstream and 2,189 cells per second upstream.
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.
Permanent Virtual Circuit (PVC) per ATM forum UNI Version 3.1.
32 virtual circuits that can simultaneously connect to service
providers for sessions encapsulated either as PPP or RFC 1483
Bridging/Routing.
