On voice transmission over lossy IP networks: A case study for advanced embedded micro-processors

Since traditional TDM based voice switches can not be efficiently applied in the packet networks, improvements on data voice multiplexing based on TDM are needed for appropriate usage in some extent. Transforming TDM voice data into IP packets can realize flexible data switching, and in this work, we present a data voice multiplexing based scheme on the embedded micro processor MPC8280 to implement the data processing. Moreover, a series of thorough tests have been done under this prototype for performance evaluations.
