ISDN BRI LINK RESTORATION WITHOUT LOSS OF CALLS

摘要

Determining by a telecommunication switching system, in response to the initialization of a new BRI interface, if a communication terminal connected to the new BRI interface is presently active on another BRI interface within the telecommunication switching system. If the answer is yes, then the telecommunication switching system automatically transfers all active calls to the new BRI interface from the other BRI interface preventing the loss of the active calls.
