摘要: A method or system or apparatus provides improved digital communication. In one aspect, flow control in performed by receiving status preprended to data units in a combined data channel, where the status data indicated the available status of a number of far end receiving channels. Thus data may be sent only to available receiving channels. In a further aspect, a frequency reference may also be transmitted by including data in data units in a combined channel. In a further aspect, an active channel can be selected among two redundant channels by use of an active bit in said data units. The invention has particular applications to ATM-type communication systems and may also be used in other communication systems.
