Most 3G systems allocate 64K for voice - equivalent to fixed line (i.e.
VGE). As far as I can see, in the medium term there will only be one
reason to keep a PTSN, and that's DSL. But as other broadband solutions
reach maturity (and cable racks up the pressure), that's a very slender
saftety margin.

Hi Benedict,
I agree with you that when 3G networks will be up, running and
reliable, operators will use them as a capacity reserve for voice
traffic. However, just remember that GSM took years to arrive at
a good level of reliability, to solve all roaming issues etc. How
much will take 3G to reach a similar level? Conversely, having a
low-quality voice is probably the most powerful factor holding
back people from throwing their fixed line in favour of mobile.
Finally, fixed line is coming to new life thanks to ADSL and (who
knows?) new fancy, multipurpose fixed terminals. My bottom line is that
mobile will never substitue fixed telephony. They are simply two
different things, that solve different (only
partially overlapping) needs.

I can't disclose info, but I know that also big operators in
high-density
populated countries are investing *a lot* in EDGE.
