Abstract
The bit streams, transporting the frames, received from lines (6) are placed in register 12 in such a way that n bits are processed in parallel during a time interval T. Parallel processor 10 counts the consecutive logical '1' bits beginning at the low order (left most) bit of the n bits received in interval T and from the bits received in the previous interval T-1, to determine when this number is found equal to 5 which bits have to be deleted, and when this number is found equal to 6 whether a flag is received. As a result, it reassembles N-bit characters, with N<n, in register (16). The frame characters to be sent on lines (6) are stored into register (28), and processed in parallel in a time interval T by processor 10 which inserts 0 after five consecutive logical '1's' as a function of the value of the N bit and as a function of the bits of the previous character, to store into register (32), the bits which are sent on lines (6).
