Michigan has mandatory thousands block pooling, and active LNP in most of those exchanges. I'm sure many of these other states are the same. Blocking this is a really dangerous thing to do, even if you don't care that the FCC would take a dim view. 906-204 for example has cingular cell phones in it. -Paul Ujjval Karihaloo wrote:

What are some of these NPA-NXX's out of curiosity?

I don't have that level of knowledge of their network, but I can easily believe they'd only have tandem trunking in some of these rural places.

Yes, number of Tandem trunks and/or PRIs.
Remember that Level 3's voice service was born out of their managed modem service. As the modem business (especially that of their really
large
wholesale customers) started declining, that capacity was converted to (or shared with) IP media gateways. Therefore areas that didn't have a large capacity in the modem world didn't have a large capacity for calls.
Yes, that I know, but my understanding was that this applies to origination. That is why they have direct end-office trunks to nearly everywhere.
How does the termination architecture work? I would assume it's like any other large CLEC and/or IXC: by default, they connect to a POI and have tandem groups from there, and also ride their own network to select end-offices in which colocate equipment for the purpose of generating UNEs, when/if there is switching equipment there.
