	This concerns ESS machines only.  When I worked on ESS  software
sometime back there  was a a  big program to  convert all customer  dial
receivers to  combimed  TT/Dial.   ANY customer  served  could  outpulse
either and the  machine would recognize  it.  This obviously  simplified
assignment of Line Equipment.
         There is (was) a  software feature called TOUCH-TONE  Detection
on Dial  Pulse  Lines.   When  this  feature  did  its  self-explanatory
function, the switch would then  (depending on the parameter  settings.)
either (1) Deny the call OR (2) Complete the call and print a message on
the Maint TTY.
         What the operating companies did with the printouts is open  to
speculation, I suspect they ignored random casual use an went after  the
constant users.
         I agree its  a rip  to charge  extra for  something which  aids
TELCO in call completion.
