Abstract

PURPOSE:To realize the line concentration, multiplexing or exchange in the time- division way, by giving the access to the temporary memory device for velocity conversion directly from the side of 4 wires and through the address designating circuit. CONSTITUTION:The information of e.g. two units of time slots arriving from 2-wire side terminal 1 with every frame cycle Tf is stored in reception temporary memory device 8 via receiver 7. In reading address designating circuit 10, the preceding signal is read at the fixed time slot position of frame cycle Tg and via 4-wire type terminals 3 and 4, and then the next signal is read at the fixed time slot position of the next cycle Tg each for the information stored temporarily. On the contrary, the two units of information which are supplied to the fixed time slot position of two cycles Tg via terminal 3 are written successively into transmission temporary memory device 6 via writing address designating circuit 9 and then read out every two units from device 6 in cycle Tf. Repeating such operations, the information of an optional time slot within the frame of the 4-wire side can be transmitted and received to and from the 2-wire type transmission line.
