Abstract

PURPOSE:To simplify the operation by providing a circuit switch which can switch the telemeter circuit to the telephone circuit and then securing an automatic switching via the hook switch between the telemeter circuit and the telephone circuit. CONSTITUTION:The telemeter boards 1A and 1B plus the telephones 2A and 2B are provided to the opposing stations A and B. The circuit switches 3A and 3B are provided between the board 1A and the telephone 2A as well as between the board 1B and the telephone 2B each, and thus the telemeter circuit 4 can be switched to the telephone circuit. The hook switches 5A and 5B functioning as the telephone calling switches close their contacts when the telephone is hooked off and open the contacts with the telephone put on respectively. The telephone switching circuits 6A and 6B are connected to the boards 1A and 1B each via the operation of the hook switch of the telephone, and the telephone call signal is transmitted to the remote station via the circuit 4. And an automatic switching is given between the circuit 4 and the telephone circuit with operation of the switches 3A and 3B.
