Meinberg are nice people with good hardware. They can do 2048KHz from
GPS and other timing signals, for instance. Then again, some router
vendors
A couple of thoughts here:
1) I know at some sites there is an external, shared, GPS antenna which is
run through a distribution amplifier to clients. Worth checking into just
in case it exists and they forgot to offer it to you.
2) Do you have any specs on what you need for the TDM clock?
Sure. They have a BITS service. I'm just checking out all of my options. It'd
be nice to have my own stuff, but that may not be feasible (or possible once
CDMA goes away).
Are any of you coloed with Frontier? Have you gotten them to let you install a
GPS antenna?

What if you use different carriers for termination and origination? How
does your termination carrier validate that your origination carrier has
allocated certain numbers to you and that you're therefore allowed to make
outbound calls with a caller ID set to those numbers? That doesn't sound to
me

This 1000%. Once legal liability is in place, the
Chris it would be trivial for this to be fixed, nearly overnight, by

But the carriers don't want that, so now we have to create tons of
technical half solutions to solve a problem
Isn't a major problem with CDMA-based sources that the networks they depend on
are getting shut down?
If so, I would imagine there will be timing servers based on the
replacement cellular technology. Might ask EndRun or one of their
competitors about it.
