摘要:
The modular switching network for time-division telephone exchanges, which may be applied to small-capacity time-division telephone exchanges, is constituted by the direct connection of pairs of subscriber and trunk line connecting units by PCM digital trunks, each connecting unit comprising a concentration-deconcentrator device for serving the subscribers associated with this connecting unit.
