Abstract
PURPOSE:To eliminate the converter corresponding to the circuit by installing the envelope/non-envelope converter inside the exchange, thus securing the easy connection between the data terminals featuring the different signal systems. CONSTITUTION:Circuits L10-L1n are changed into the sampling information by circuit termination circuit LT and in the timing index system, multiplied through multiplexer MPX and the undergo the time-division exchange via time-division switch 3. The exchanged data is restored to the original information via demultiplexer DMPX and then transmitted to the circuit. In the case of the exchange between the envelope circuit and non-envelope circuit, the time-division exchange is carried out via format converter device CONV like, for example, terminal t1, time slot shifter TSS1, terminal t2, format converter device CONV, terminal t3 shifter TSS2 and terminal t4 each.
