You obviously don't understand how an Urban works. I stated that we do
not put more than one voice circuit on a single DS0 channel. The Urban
puts one voice circuit on each DS0 channel.
Your poor connect rates have more to do with the multiple A/D and D/A
conversions. The fact that they use concentration does not affect the
connect rates at all. Period. End of Story.
