ABSTRACT:
A multiplexer is arranged for interleaving blocks of bits from tributary lines. Sequences of blocks of digital bit streams are received in frames from each tributary line. Each frame includes tributary line identification information and plural blocks of bits. Each block of digital bits includes plural data bits and a parity bit. The sequence of blocks from one tributary line also includes in a periodic one of the parity bit positions, a bit containing control information. The blocks of digital bit streams are multiplexed into a single multiplexed bit stream.
