Abstract
Abstract A digital signal channel distributor is composed of two digital signal channel subdistributors of which one digital signal channel subdistributor assumes the transmission in one direction and the other assumes the transmission in the opposite direction, whereby a switching is possible within one direction. The digital signal channel subdistributors are connected to one another via an interface for clock adaptation or synchronization.

Claim 1
Independent Claim
177 words
A digital channel distributor comprising: a plurality n of gates each including an input and an output and arranged in first and second groups; a first digital signal channel subdistributor including n/2 interfaces each including an input connected to a respective input of said gates of said first group, an output connected to a respective output of said gates of said second group, and a first monitor operable to emit first multiplex addresses and first multiplex signalization information and a first multiplex clock; a second digital signal channel subdistributor including n/2 interfaces each including an input connected to a respective input of said gates of said second group, an output connected to a respective output of said gates of said first group, a second monitor operable to emit second multiplex addresses and second signalization information and a second multiplex clock; each of said digital channel signal subdistributors comprising a clock adapter connected to the respective monitor and operated by the respective multiplex addresses to adapt the first multiplex clock to the second multiplex clock and vice versa.
