[c-nsp] Transporting TDM voice DS3s over Ethernet

[Clayton Zekelman]

Point me to such a commercial product that will correctly transport TDM voice frames across Ethernet at that scale that does not use VoIP or DSP's.

If one does not already exist, then basically, you're describing a science fair project.
