No, there are no TDZ's here yet; I think the ICC is still mulling over
local loop competition.  It certainly isn't a reality in 1990.  [There
are several buildings along the Chicago/Park Ridge border that
straddle the boundary between the two cities (and thus the boundaries
of telqi, cable providers, natural gas suppliers, and area codes); all
but one of them (several apartment buildings and single-family
dwellings, no businesses) have an address in one city or the other and
probably the utilities follow suit.  One house has two addresses,
apparently with Illinois Bell phone service from its Chicago side but
Northern Illinois Gas from its Park Ridge side.]

The clue of having both telqi at a Dunkin' Donuts in Des Plaines led
me to the one on Elmhurst Road, just south of Thacker (barely in IBT
territory), there being none on Higgins (there is one on Higgins in
Elk Grove Village, the next town west, but it is very deep into
IBT-Land).  It had two Illinois Bell paystations and no COCOTs.

However, the Dunkin' Donuts on Oakton, just west of Lee, well within
Centel's satrapy, had almost what Jeff described: a Centel payphone in
the vestibule and two paystations on the back wall, of which one was a
second Centel coin phone and the other was a COCOT in a housing that
resembles IBT payphones.

Why any informed person would use the COCOT, except in an extreme
emergency with both the Centel phones in use, is beyond me.  Even
then, there are a very large number of other retailers at Oakton and
Lee, many of whom have Centel payphones at their establishments.

I'll let the Digest readership know if I spot anything telephonically
odd at the other Dunkin' Donuts in Des Plaines (at Rand and Miner)
next time I'm in its vicinity.  The recent increases in gasoline
prices have cut seriously into my joyriding.
