==CLLI codes to calculate distance==

From the intro:

:'''CLLI codes are useful to telecommunications companies for ordering phone service, for the rating of call detail records for billing purposes, and to assist in tracing calls. CLLI codes are associated with Vertical and Horizontal coordinates (frequently abbreviated to "V and H coordinates"), which were developed by AT&T researcher Jay K. Donald to provide a relatively simple method of calculating distance between two network locations. Various mileage-sensitive services are priced according to the V and H coordinates associated with the two endpoints' CLLI codes.'''

I'm a little unsure about this... the ''rate centre'' (and the V/H coordinates for billing purposes) is not the ''wire centre'' (the ___location of the actual switch, which has its own V/H coordinates). [http://www.localcallingguide.com/lca_rcdist.php?npa1=905&nxx1=625&npa2=416&nxx2=620] indicates that +1-905-625 and +1-416-620 are 21km (13mi) apart (for billing purposes), even though physically both are on the same switch [http://www.localcallingguide.com/lca_prefix.php?switch=TOROON29DS0].

[[Odessa, Ontario]] appears to be a [[legal fiction]] in that it has its own rate centre, coordinates (V: 04634 H: 02220), local calling area and CO codes (+1-613-386) even though the exchange physically does not exist[http://www.localcallingguide.com/lca_exch.php?exch=156330] (a search for a "386 exchange" only returns a CLLI for a [[Collins Bay, Ontario]] switch CLBAON02DS0 at V: 4629, H: 2204, which is the +1-613-389 suburban exchange).[http://www.telcodata.us/view-switch-detail-by-clli?clli=CLBAON02DS0] [[Sydenham, Ontario]] (613-376) and [[Deseronto, Ontario]] (613-396) appear to be just as fictional. If there's no physical exchange building, is there a CLLI for these basically-fictional (but still very much billable) rate centres? [[User:K7L|K7L]] ([[User talk:K7L|talk]]) 03:06, 3 June 2013 (UTC)
