was this invented by BC Tel? —Preceding unsigned comment added by 24.244.73.150 (talk) 01:17, 29 November 2009 (UTC)Reply

No, this is an Americanism and was concocted by Bellcore. CLLI codes do exist for all Telus exchanges, but the concept did not originate there. K7L (talk) 03:06, 3 June 2013 (UTC)Reply

CLLI codes to calculate distance

Latest comment: 12 years ago1 comment1 person in discussion

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). [1] 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 [2].

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 (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). 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? K7L (talk) 03:06, 3 June 2013 (UTC)Reply
