PURPOSE:To arbitrality set the length of a call information line between a distributor and a time division switch device, by generating the amount of delay required in a time division switch device through the setting of the initial value of a memory access counter. CONSTITUTION:Call information 0, a frame pulse 1, and a clock pulse 2 from a distributor (not shown) are applied to a phase matching circuit 4 via a call information line G and the phase is corrected. A write access counter 9 is set to zero with a frame pulse 1' and counts a clock pulse 3 synchronized with the time slot width. The output acts like a write address of a channel memory 6 and a call information 0' is written in the memory 6 via a serial parallel conversion circuit 5. In a read access counter 11, the initial value determining the amount of delay is set with the frame pulse 1', then the clock 3 is sequentially counted and the call information in the memory 6 is read out via a storage memory 10. |
