Abstract:
1. A method comprising: transmitting data belonging to an asynchronous transfer mode (ATM) connection in a time-division frame divided into a plurality of time slots, the data having a type being one of a variable length ATM Adaption Layer type 2 (AAL2) packet or an ATM cell, each time slot taking an eight-bit byte, consecutive eight-bit bytes of said data being located in consecutive time slots of at least one group of time slots of said frames, a first eight-bit byte of said data being placed at a time slot marked by a pointer equal to a rank of said time slot within said corresponding group of time slots minus one; selecting a virtual circuit address based on the type of the data, the virtual circuit address defining a virtual circuit for the transmission of said data marked by said pointer within the time slots of the frame; associating said pointer with the virtual circuit address, said virtual circuit address and pointer occupying a specific time slot of said corresponding group of time slots that is distinct from the time slots in which the data is transmitted; transmitting said specific time slot; transmitting said data marked by said pointer via said virtual circuit; and transmitting, via said virtual circuit, consecutive data of the connection within the time slots of a frame belonging to the same group of time slots as said data pointed to by said pointer.
