Out of curiosity what does TSPS stand for? Also what is TOPS?

Subject: Credit calls, etc.
To throw some more ideas into that bucket:
I heard someplace that they are going to implement a central-database
system wherein the user will enter his credit code from the phone and
then make his call. This would supposedly eliminate the use of
'synthesized' credit codes or out-of-date ones, or codes that the
sys people can tell the machine to ignore because of problems. What
it will introduce of course is being able to beat on codes without
human intervention [operators] and I have a feeling that it would lead
to about the same crime rate as before!
I used to be a TSPS type, so I know basically how it goes from the
'other end'. I also tried to start the first list of this type
but it was unmoderated and based at MC and got out of hand. Anyhow:
If it's TSPS, from about a year ago, just ask. It's one of my
favorite flamage topics.

Subject: direct credit card dialing
I know that there are plans for this in New England. There may even
be systems in operation. Sorry to be so vague, but I don't remember
the details. Just thought you'ld like, to know that that it's coming (soon).

Subject: The reason a switchook flash is used rather than a TT sequence
The piece of hardware which listens for and decodes Touch-Tone input
from the phone is fairly expensive. Modern central offices and PBXs
have many less of these than there are telephones, and they are only
connected to the line when needed. The only thing on the line when
you have established a call is the piece of hardware that looks to see
if you have hung up the phone (permanently or momentarily). You have
to flash the switchhook in order to get the switching machine's
attention so that it can connect a Touch-Tone register across the
line.
Even if the registers were cheap -- you wouldn't want telephone
features to be activated by a TT sequence. That would interfere with
your ability to transmit data using the Touch-Tone pad.

Subject: Speech Synthesizers vs. noisemakers
That would be nice. Of course, it would have to handle a large number
of languages. There would have to be a language attribute associated
with each line, and a command to temporarily set the attribute to
some- thing different when a guest from another country wants to use
your phone. What would the error message, "Unsupported language
selected" be presented as?

Subject: (Almost) direct dialing of toll stations?
cc: Hamilton.ES
Does anyone know if Telco has any plans for automating calls to
toll stations? Right now, if I want to call Deep Springs College,
California, I have to call my local operator and say "calling
Deep Springs #2 toll station, operator's routing
714+ 054+ 181". In many parts of the country, you have to spend
ten minutes talking to three levels of supervisors to convince
the local operator that such a place even exists. It seems like
I ought to be able to dial the routing codes myself to get me to
the Bishop, California operator, who would then ring the toll
station and use some sort of out-of-band signalling to tell my
local exchange whether and when to start and stop billing.
