Abstract: PROBLEM TO BE SOLVED: To economically process an asynchronous transfer mode (ATM) cell with minimum transfer delay by allocating the memory position of a time slot memory to the payload byte of an independent cell and adjusting the writing of payload data into the allocated memory position. SOLUTION: A communication exchange transmits/receives an asynchronizing signal constituted of the independent data cell having individual cell header and payload, which one of signal input/output ports 807-809 allocates to a communication channel. An exchange module processor 801 and a message handler 802 selectively control time slot mutual exchange 820 for setting a communication route between the communication channels. The memory positions of the time slot memories (data RAM) 830 and 831 are allocated to the payload bytes of the independent cells and a signal for adjusting the writing of payload data to the allocated memory position is generated.

Abstract: An enhanced communication network switch utilizes a Time Slot Interchange facility to decompose and compose composite ATM cells that each comprise a 5 byte header and a 48 byte payload. The payload comprises data from a temporarily defined set of call connections of a virtual 48 channel transmission facility; and t he switch comprises a Cell Header Decoder comprising a plurality of records which dire ct operation of the TSI to decompose corresponding received composite ATM cells . Atthe time that a cell is committed to call connection service, the switch seizes and initializes an idle record in the Cell Header Decoder. For the purpose of composing a composite ATM cell for transmission to an ATM line, Cell Header and payload data are read from memory locations assigned t o call connections served by the cell during the time slots currently assigned to t he cell.
