ABSTRACT:
In a transmission system, which includes one or more digital repeaters in a transmission line and a digital multiplex/demultiplex branching unit, a code for supervising the digital repeater or repeaters in an in-service state is transmitted according to a data sequence signal obtained through bit-by-bit time-division multiplexing of at least two different kinds of digital signals. The supervisory code has a configuration of a transmission line code obtained by dividing the digital signals into blocks of bits corresponding in number to the sum (n.times.m'+1) of the product of the number n of channels of the digital signals and positive odd number m' and one and adding after each of the blocks a number of parity bits (supervisory bits) corresponding to the respective digital signals equal to the number of the channels, i.e., has a bit configuration of n(m'+1)+1.
