Abstract
A transmitter having an interface module to serve as an interface between ATM cells and synchronous frames. The interface module comprises a plurality of first physical paths for inputting ATM cells with channel identifiers given thereto to identify channels respectively; a second physical path for outputting a synchronous frame signal; a channel identifier inserter for inserting the channel identifiers, which are given to the first physical paths where the ATM cells are inputted, into predetermined areas of the ATM cells; and a mapper for mapping the multi-channel ATM cells with the channel identifiers inserted therein to one synchronous frame signal and outputting the same to the second physical path.
