SIMULTANEOUS TRANSMISSION OF VOICE AND NON-VOICE DATA ON A SINGLE NARROWBAND CONNECTION

摘要

In a publically switched telephone network (PSTN), a method and a system for simultaneously and independently multiplexing voice and non-voice data over a single, commonly shared PSTN access line. This is accomplished by packetizing the voice and non-voice data into minicells, and then multiplexing the minicells into a single data stream for transportation across the commonly shared PSTN access line. Once the minicells containing either voice or non-voice data have been transported over the single, commonly shared PSTN access line, the data is simultaneously and independently routed to distinctly different end-users according to the routing information stored in the header portion of each minicell.
