PURPOSE:To ensure a high-efficiency multiplication as well as to secure an easy decision at the reception side for the slot allotment process at the transmission side for the time shearing multiple control system with which the idle time and slot are allotted when the transmission requests are given from terminal circuits of different transmission velocities. CONSTITUTION:The time slot on the circuit forms one frame shown in A and then allots previously slot T0 to channel CH0 like CH1 against the terminal of 50BPS like B. For the terminal of 100BPS, T0 and Tn plus T1 and Tn+1 are allotted to CH0 and CH1 respectively. In case the data transmission requests are given at one time from several units of terminal circuits, the request from only one terminal is made effective based on the expected priority sequency with other requests put under the holding state. The indication signal is provided to the idle CH, and the idle CH allotted by occurrence of the transmission signal request receives the transmission start indication signal (one signal row) instead of the idle state signal (zero signal row). Thus the reception side recognizes the allotment state based on the signal change. |
