Abstract:
A method for connection-oriented transmission of message streams having compressed, digitized voice information in a communication network having a plurality of at least partially meshed communication systems, comprising the steps of:at least temporarily establishing connections via the communication systems using signaling information;taking compressed, digital voice information from a message stream arriving in a respective communication system;communicating the digital voice information in a communicated compressed connection-conforming manner in the respective communication system;inserting a further message stream when the respective communication system is a transit communication system with respect to the compressed, digital voice information;digitized voice information with a bit rate of 64 Kbit/s being compressed using a compression routine to form voice information with bit rates of 64 Kbit/s/n, where n=2, 4, 8, 16, whereby the compression routing according to ITU standard G.728 is realized given a compression to 16 Kbit/s.
