The master station (1) allocates time slots (d) and (i) to two slave stations with which it wishes to communicate, for example, the second slave station Ou and the nth slave station (4n), respectively. The second slave station 4 puts the signal from the signal input terminal (6) on the time slot (d) and sends it to the upper multi-line (2), and receives the received data from the time slot (d) of the lower line (3). Output to the output signal output terminal (5).

ることを目的とするものである。Since the conventional communication control method is configured as described above,
The main station (1) had the drawbacks of requiring a switching function and a line for two time slots.This invention was made in order to eliminate the above-mentioned drawbacks of the conventional system. By allocating the same time slot to each slave station, and receiving data by delaying the sending data to compensate for the delay in the transmission path and adding it to the received time slot data, the master station does not need an exchange function. The purpose of this is to provide a communication control system that allows communication using only one time slot on the line.

ているため詳細な説明は省略する。Based on the common line signal, the master station (1) detects the call and confirms the slave station number of the other party based on the common line signal from the second slave station (42) that initiated the call. (1) is based on the common channel signal, and the time slot (i
). The two slave stations U (4n) then transmit and receive data in time slot (i). The procedure for allocating time slots to this slave station is well known, so a detailed explanation will be omitted.

Then, the transmission signal from the signal input terminal (6) and the upper υ times M (
The data included in the time slot (i) of 2) is added by the adder circuit (7) and sent out. In this embodiment, the n-th slave station (4n) has a time slot on the upper line) (i
) has only the transmission data of the n-th slave station (4n), and the second slave station (6) has only the transmission data of the n-th slave station (4n) in the time slot (i).
n) and the transmission data of the second slave station (6) are added.

8), and the downlink (3) is delayed by the amount of line delay.
The adder circuit (9) adds (subtracts) the data in time slot (i) to remove its own transmitted data, extracts only the other party's transmitted data as received data, and outputs the received data as a signal. Send to terminal (5).
