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.
