PCT No. PCT/FI93/00130 Sec. 371 Date Sep. 30, 1994 Sec. 102(e) Date Sep. 30, 1994 PCT Filed Mar. 30, 1993 PCT Pub. No. WO93/20635 PCT Pub. Date Oct. 14, 1993A method for establishing a user-network interface in a digital transmission network for a cell-based digital 140 or 155 Mbit/s ATM signal, and a network interface embodying the method. The interface includes an input buffer controlled by a predetermined policing function for receiving the cell-based signal and adapting the transmission speed of the signal to the actual transmission speed of the transmission network; a mapper for forming cell blocks of N consecutive cells from the cell-based signal and for adding N overhead bytes to each cell block; and a multiplexer for multiplexing the output signal of the mapper byte by byte into N separate output signals of about 1.5 Mbit/s, 2 Mbit/s, 6 Mbit/s or 8 Mbit/s. |
