PROCEDURE FOR CONTROLLING THE SET-UP OF CALLS WITH TRANSMISSION CHANNEL REQUIREMENTS OF DIFFERENT NETWORK TERMINATIONS

摘要

To be able to efficiently and reliably control the set-up of calls in telecommunication subsystems which serve as local message transmission loops of telecommunication systems with network terminations which differ according to the transmission channel requirements, a first network termination explicitly indicates, for instance, in the form of a parameter, the desired and requested transmission channel in a call set-up message of the network termination to the counter part in the telecommunication system.
