- It truly is a dumb question, probably a definitional one. Are all
- intra-LATA calls non-toll, and all inter-LATA calls toll, by
- definition?
-
- Following on to that, can anyone suggest some good basic documents
- about the structure of telecom in the US, so I don't ask these
- questions again? Also, various people have posted LATA information.
- Is information about what prefixes of a given NPA are in a given LATA
- (if there's > one LATA per an NPA) available, and if so, from whom?
- What's a good first phone number to call with questions like this?
-
-
- Inquiring minds need to know.

- [Moderator's Note: LATAs are the geographic territories each telco is
- allowed to serve. It could sort of be compared to their 'franchise'
- territory. Usually you'll see one telco per LATA, but not always.
- LATAs can be and frequently do cover a wide geographic area. In such
- cases, there will probably be toll calls between various intra-LATA
- points. On the other hand, two communities which sit on opposite sides
- of some boundary line (such as a river, or a state line dividing an
- urban area in two parts) may well have a different LATA (and possibly
- a different telco) on each side of the boundary -- yet calls between
- the two sides will be treated as 'local calls' by mutual agreement
- between the telcos if there happen to be two of them. I guess it would
- be safe to say that with the exception of places right along the edge
- of a LATA, inter-LATA calls would in most cases be a toll call; not
- because of the different LATAs, but because of the mileage involved.
- Does anyone know the exact rule by which LATAs were drawn up? PAT]
