CONNECTION IDENTIFIER INTERWORKING APPARATUS IN ATM SWITCHING SYSTEM AND METHOD THEREFOR

摘要

PURPOSE: A connection identifier interworking apparatus in an ATM switching system and a method therefor are provided to solve a problem of a traffic manager restricted in a range of VPI(Virtual Path Identifier) and VCI(Virtual Channel Identifier) fields by allowing the traffic manager to use a connection identifier created with VPI and VCI. CONSTITUTION: An origination OAM processor(521) generates an origination connection identifier(In_Contag) by using an input physical link number and an input VPI(In_VPI)/input VCI(In_VCI), converts a VPI field into '0' and VCI field into an origination connection identifier, and then, sends a cell to an origination traffic manager(522). Since the outputted cell is inputted to a destination traffic manager of a different giga-bit matching module through a switch module, the origination traffic manager(522) leaves the VPI field as '0' as it is, converts the VCI field from the origination connection identifier(In_Contag) into a destination identifier(Out_Contag), and then, transfers the cell to a switch matching unit(525).
