Method and device for communication between switches of different types

摘要

The invention provides a method and an apparatus for controlling the establishment of a communication link between two parties connected to switches of different types, such as a circuit switch and a packet switch. The apparatus includes a call manager (332) common to the different switches for selectively establishing the intra-switch connection paths in each switch in order to set-up a communication link between the two parties. An inter-switch data channel allows data to be exchanged between switches of different types such as to complete the communication link. <IMAGE>
