摘要：
In a forty megabit per second TDM signalling system in which twenty 2 megabit per second signalling streams are combined, one of the twenty primary signalling streams is inverted and substituted for one of the other signalling streams. By using adjacent channels the forty megabit signal stream has a guaranteed change of data at least once every twenty bits. The system facilitates clock recovery and synchronisation in apparatus employing bi-phase mark encoded data.
