Abstract
Method of processing asynchronous characters in order to transmit them over an ATM network (10, 12 or 16) of a communication system having a first endpoint (36) and a second endpoint (38), a first group of one or more Data Terminal Equipments (DTE) being connected to the first endpoint and a second group of one or more DTE's being connected to the second endpoint and wherein data are transmitted from the first group of DTE's to the second group of DTE's by the intermediary of the ATM network. Asynchronous characters are processed as they are received at the first endpoint from the first group of DTE's by removing Start, Stop and parity bits. A block is generated consisting of one or more processed asynchronous characters received in sequence from a particular DTE of the first group of DTE's. An ID byte is added to the block to identify the transmitting DTE, yielding a data unit. A plurality of such data units are concatenated to build a data unit frame. The data unit frame is encapsulated into an ATM cell structure in order to transmit the frame over the ATM network.
