PURPOSE:To use various transmission and reception equipment having different performance in common and to improve the flexibility and versatility of a comminication system, by setting the transmission speed of synchronizing control burst and data burst constituting the frames into plural values. CONSTITUTION:Signals having different clock speeds are mixed in one frame F. The clock frequency has the relation of fp1>fp2>fp3, the fp1 is transmitted and received between slave stations 10 and 13, the fp2 is among 10, 11, 13, 14, and the fp3 is received and transmitted among slave stations 10-15. The clock frequency of a synchronizing burst group S is received at each slave station in common by setting it to the fp3. |
