exactly and that's the whole point! it has been the whole point since i wrote
my statement... a POTS line and standard POTS phone do not need any other
equipment on the customer end... this distinction between dial tone on the bare
wires is exactly one of the major distinctions between POTS and ISDN or other
some digital services... DSL, for example, can run on either dry or wet
pairs...

when i was in telco school and i learned that there are no load coils on ISDN
lines, i knew they would not handle analog signals properly and that they would
require specific equipment to be present and working on the customer
premises... load coils add inductance to offset the capacitance of the wire
pair... some years back i asked about getting ISDN... the telco wanted $900US
per half mile to "condition the line"... that "conditioning" was simply
removing the load coils... i told them that the run was 15+ miles... i'd do the
"conditioning" on their lines and we'd split the $27000US... i'd get that part
of the service for free because they'd owe me $13500US which i'd just hand
right back to them thus spending no $$$ out of my pocket...

then there was the discussion about the monthly cost of the line... local calls
were free, like always... LD were metered by distance... i didn't feel like
getting the FCC involved to beat the telco down and force it to provide ISDN
for the same rate as POTS but i could have... there's a bit of a difference
between $40US per month and $400+US per month... these outrageous charges are
exactly why ISDN never went anywhere here and in other places...
