Abstract
PURPOSE:To make it possible to control two kinds of independent switching route to adopt a free line constitution, by providing a line group selecting circuit and a switching control circuit which can transmit two kinds of switching command and returning command. CONSTITUTION:Signal 1 of switching command 0 and line group number 6 from switching control circuit 104 are transmitted to switching circuit 107, and #0 line control unit 101 is connected to MODEM 102''. Meanwhile, signal 3 of switching command 1 and non-line group number 7 from switching control circuit 104 are transmitted to switching circuit 106, and #0 line control unit 101 is connected to MODEM 102 and 102'. In the returning operation, returning operations reverse to switching operations can be performed by signal 2 of returning command 0 and line group number 6 and by signal 4 of returning command 1 and non-line group number 7.
