Okay. This is good for LD.<br>
<br>
In case of A-Z list the LD idea probably won't fit.<br>

<pre wrap="">I have been considering building a "route only" database, to also be
publicly available. This would serve two purposes: it would be a
canonical (hopefully accurate) list of routes (country, city/region,
route type), and would also provide a template to be used for an A-Z
termination provider to provide their rates. If the site allowed the
route database (or portions thereof) to be downloaded as CSV/SXC/XLS,
then I could provide the database to a potential termination provider,
have them fill in the numbers (or they could provide me their
already-filled-in template they have on file) and then it would be easy
to merge the numbers in my company's routing database.
As it stands now, pretty much every provider has their own "rate chart"
format, and many of them are incomplete and/or inaccurate. I wasn't
really thinking about actually building a _rate_ database, since the
rates are frequently not public, based on volume, etc.

<pre wrap=""><!---->Here's how it *really* works.
Telcordia LERG contains the real routing information. For a given NPA-NXX,
it maps into LATA and into OCN. Now, carriers group OCNs into "tiers"
(just groups of carriers with similar rates). Usually Tier 1 is RBOC,
Tier 6 is NECA, and those tiers are uniform across all termination
providers. All other "tiers" are subject to individual carrier's
termination agreements, and they can be "CLEC", "Cellular", "RBOC
Cellular" etc. Those OCN-Tier mappings are somewhat individual among
carriers who sell termination.
LERG costs 3000$ for a copy, and something like 500$ for monthly updates.
You can look up LERG info at <a class="moz-txt-link-abbreviated" href="http://www.telcodata.us">www.telcodata.us</a> for free, but you can't get
free access to LERG. Also, I have a feeling that Telcordia won't look too
kindly at freely downloadable LERG-extracted information, but I need to
check LERG licensing to be sure.
If you want to let termination providers list their rates, you can either
allow them to spit out their entire NPA/NXX->rate map (huge), or two maps:
OCN -> tier, and lata+OCN -> rate

<pre wrap="">I'd like to discuss this further; I have equipment that I could host
this with, and would be happy to do so (again, as Alistair said, it's
good advertising plus we'd be giving back to the community).
If this is off-topic for this mailing list, email me directly and we'll
try to get something figured out.
