PURPOSE:To reduce the hardware quantity by executing serially a synchronization processing of multiplexing data at every channel. CONSTITUTION:The channel synchronizing system for a multiplexing data communication equipment is constituted by providing a memory 1 for storing temporarily multiplexing data, a time division channel synchronizing pattern detecting circuit 2 for deciding whether a synchronizing pattern of a multi-frame of every channel of the multiplexing data is normal or abnormal by a time division, a time division channel synchronizing data counter 4 for counting the number of times of a normal synchronizing pattern, and the number of times of an abnormal synchronizing pattern in each channel, and a phase of data of the multi-frame for shoving a bit position in a multi-frame synchronizing pattern by a time division at every channel, respectively, and outputting a synchronizing state and the phase of the multi-frames based thereon, and a memory 5 for storing channel synchronizing data for managing the number of times of a normal or abnormal synchronizing pattern of each channel and the phase of the data of the multi-frame by a time-division. |
