Abstract: ATM physical class subscriber access processor includes: a transmitting cell processor(29) for receiving ATM cell from ATM hierarchy, and performing VC-4 pay load mapping; VC-4 generator(30) for generating VC-4(virtual container-4) signal; a pointer generator(7) for mapping a transmitting VC-4 signal to STM-1 frame; a frame generator(31) for generating STM-1 frame; a frame terminator(34) for processing a STM-1 frame; a pointer discriminator/processor(21) for detecting VC-4 signal from STM-1 frame; VC-4 terminator(33) for processing an error detection information and an overhead information; a receiving cell processor(32) for outputting ATMcell to ATM hierarchy; a connector(28) for connecting between the above elements(21,29-34) and the CPU. Accordingly, the ATM physical class subscriber access processor real-time processes a data error, accumulates all statistic errors generated on a transmission line path, and includes ATM cell by using asynchronous method without regard to a service speed of ATM cell.
