Abstract

PURPOSE:To enable the connection control in almost the same time as the time required for the connection within the same network even in the connection between different types of networks such as packet transmission network and electric exchange network, through the transmission of dial information with the fixed time slot. CONSTITUTION:A signal separation circuit 2 feeds the off-hook information to a transmission control circuit 4 for start with the off-hook of a telephone set 1, and the dial pulse from the telephone set 1 is fed to the transmission control circuit 4 with the signal separation circuit 2. The communication information after the connection with called subscribers is fed from the circuit 2 to the packet circuit 3 for packet, and called subscriber number is added and transmitted as the address information at the transmission control section 4. The communication information transmitted via the packet transmission line 6 is converted into audio signal at the packet processing circuit 8 and fed to called subscribers via the channels of the exchanger 11 from the transmission circuit 10.
