If the PSTN could overnight switch from TDM to IP, everyone would be
much happier for it; there's a lot of pain and expense going back and
forth between SS7, IP, wireless, and even older stuff like FG-D.
Unfortunately, we have a long, painful transition to undergo:<br>
<ul>
<li>On the technology side, carriers have to update, upgrade,
replace, and some time just trash existing (expensive) hardware
infrastructure of all different flavors. There's a lot of money
involved there.<br>
</li>
<li>On the business side, carriers have to figure out how to convert
their inter-carrier billing and revenue agreements that are all based
on channel and CPM models into...whatever exactly it is that's going to
replace it. And like it or not, all of the upstarts are leveraging (or
just taking advantage of) a model that allows them to exist at the
expense of the incumbents so those who stand to lose their revenue base
are understandably dragging their feet.<br>
</li>
<li>On the regulatory side, the regulations have to be adapted to
account for new forms of telephony and distribution, and these things
change very slowly because politics is involved. To add injury to the
process, states and localities derive revenue from the taxable
transactions. So if those taxes go away...something has to replace
it. We all know how easy it is to raise taxes in this current
environment so you can figure on some real pain there.</li>
<li>New carrier technology (cable and FIOS) which is not currently
open to competition is creating an interestingly skewed playing field
as some areas get a ton of new investment (most suburban and some urban
areas) while others (largely poor and rural) get skipped.<br>
</li>
</ul>
Nobody really knows how these things are going to change, but there's a
lot of really nervous people all across the incumbent and mature CLEC
space as they try to adapt their technology, processes, workforces, and
other stuff to meet the perceived demand.<br>

the complexity, nor that interconnection without TDM and/or SS7 is
possible--at least, for CLECs, but also many ITSPs that buy TDM in
order to do access that is actually reliable and interoperable.<br>
<br>
My intended point, which should have perhaps been made clearer, was
only that the use of more IP - where feasible and practical - in the
place of a circuit-switched alternative can add fluidity to the network
that can change the CAPEX formula for redundancy in a more favourable
direction.<br>
<br>
It's not magic and it certainly won't solve all the problems that
motivate the original question.
