SWITCHING STRATEGY FOR MIXED DELAY TRANSMISSION CHANNELS

摘要

A switching strategy, and apparatus for implementing the strategy, that reduces degradation of transmission quality resulting from the use of mixed cable and satellite channels in a time divided transmission system is disclosed. The type of channel preferred by a trunk requiring a connection is determined on the basis of the types of channels the trunk was assigned locally and remotely at the time of its last connection and the type of channel in the majority at the time of the determination.
