ABSTRACT:
Disclosed is an AAL2 (ATM (Asynchronous Transfer Mode) Adaptation Layer 2) switching apparatus. A cell deassembler for deassembling a payload of a received ATM cell into a CPS (Common Part Sublayer) packet, and generating a first VPC (Virtual Path Connection) by using the header of the ATM cell. A header converter for receiving the CPS packet from the cell deassembler and converting the first VPC into a second VPC by using a lookup table which have a number of VPCs and CIDs (Channel Identifiers) for changing the VPC. A cell assembler for receiving the CPS packet from the header converter, assembling an ATM cell which have the CPS packet and an ATM header generated from the second VPC.
