Isn't this dishonest? To post a question so you can supply an answer
that is an advertisement?
Just in case you aren't associated with CCMI, here's some (old) info....
CCMI at Suite 1100, 11300 Rockville Pike, Rockville, MD 20852 sells
lots of maps, books, newsletters, tariffs, etc., as well as rate databases
for the telecom industry. Call 1-301-816-8950, Ext. 835.
MD/VA LATA numbers are 236, 238, ..., 252 (even numbers only).
The TELCO for Delaware is owned by Bell of PA, so DE is part of LATA 228
(Philadelphia). LATAs 927, 928 and 928 belong to non-RBOC TELCOs in VA.
Al Varney -- I don't profit from CCMI's business, but they did give me
a free color LATA map a long time ago....
