Abstract

A controller of a communications network enables endpoints or multiple networks to intercommunicate using multiple types of bearer format (IP, TDM, ATM, Frame Relay, etc.), and enables a bearer format conversion when necessary to carry bearer channel information across an interface of the network. The network may be packet-based or circuit-based and may include gateways and associated controllers which work in tandem to transfer format conversion parameters between endpoints or networks. The format control parameters are exchanged between various controllers, i.e., call control elements, to determine the appropriate format to forward the bearer channel information across the interface and to instruct the associated gateway of the required format conversion. The determination of the necessary format conversions may occur on a call-by-call basis, or by periodically detecting and storing format conversions associated with the various endpoints and intercommunicating networks. A corresponding method is also disclosed.
