摘要： In a cross-connection network, a plurality of asynchronous input digital signals can be cross-connected to a plurality of output lines by use of time switch. The input digital signals are pulse stuffed at a common higher bit rate and are synchronized to one another by attaching extra bits. The pulse stuffed signals are assigned into serial frames in a predetermined order by the multiplex technique and are interchanged from one to another by the time switch in the time division fashion. The frame-interchanged signal is demultiplexed to reproduce the pulse-stuffed signals which are sent out to the respective output lines assigned to the frames after removing extra bits. When the input digital signals are of higher order group, each of the higher order group digital signals is demultiplexed to lower order group signals which are pulse stuffed to be synchronized to the common higher bit rate. The pulse stuffed lower order signals are rearranged by the multiplex technique to reform each of the high order group signal which is synchronized to one another. The reformed higher order group signals are assigned in serial frames and are processed in the similar manner as described above. The frame-interchanged signals are reversely processed to be separated, demultiplexed, destuffed, and multiplexed to reproduce the input signals as the output signals.

摘要： An internal frame signal producing circuit for use in a cross connection system which cross connects first bit rate signals, each produced by multiplexing m second bit rate signals at first or the second bit rate signal levels, the first bit rate being higher than the second bit rate, an internal frame frequency is predetermined to be equal to a frequency f.sub.h ' higher than a first nominal frequency f.sub.h of the first bit rate digital signals by a predetermined value, the frequency f.sub.h ' being synchronized with a second nominal frequency fl of the second bit rate digital signals. In order to obtain the internal frame signal, from m second bit rate signals, the m second bit rate signals are stuff-synchronized processed to produce m stuff-synchronized signals, each having a stuff bit, a variable bit, and vacant bit at suitable bit intervals in a frame of a frame length. The m stuffed-synchronized signals are serially arranged to make the internal frame signal. In order to compensate a frequency difference between f.sub.h ' and fl, one frame consisting of all vacant bits is assigned at predetermined frame intervals.
