Not by 1980.
First of all we had the Carterfone Agreement in 1954 which allowed you to
connect certain things up to telephone company telephones. You could not
connect up terminal equipment.
If you wanted to connect terminal equipment up to the telephone system, you
had to rent a DAA (Data Access Arrangement) from the telephone company for
two dollars a month. This provided filtration, ground isolation, and some
amount of current and voltage protection preventing you from putting too
high levels on the line.
This persisted up until the early seventies (but before the breakup) when
the FCC put in place a licensing procedure for products to be licensed for
interconnection to the telephone network. If you were a modem manufacturer,
you could get your product type-accepted by the FCC to establish it would not
unbalance the line or cause crosstalk, then sell it to customers who could
connect it without a DAA.
This remains the case today, although today the market is flooded with a lot
of crap that hasn't actually passed type-acceptance testing, though there is
nobody to enforce them.

Depends on the exchange. Long lines digital transmission started coming in
in the early 1960s, replacing FDM "Telpak" cables with TDM digital circuits.
(That's where the T in T-1 comes from.) Digital switching was a different
thing altogether... in fact you could argue the original Strowger switch was
digital. What you're talking about is "electronically controlled switching"
and in general it was a good thing... and the phone company introduced it
with no prodding from the government, because it was a profit center for
them.

Of course. They are the exact same things that the telcos want to do today.
That doesn't change anything. The pressures on the telcos are exactly the
same... and if you think that there is actual competition between wireline
telcos, you are very deluded.

No, but that sure didn't hurt matters. The thing is, the Communications Act
of 1934 _already_ made it illegal to divulge private communications to a
third party. What the politicians got busted for was already illegal, there
wasn't any need for a new law.
The ECPA does a lot of really silly things, like define a subcarrier as a
form of encryption... which means that listening to FM in stereo is
technically illegal. It was a law written without benefit of technical
expertese.

Whoops, you're right... I know that got moved, but now it has been closed so
if you DID actually have an engineer come to investigate an interference
issue, he'd be coming down from Landover Maryland. The chances of that
happening are... slim....

Yup. But I can also go to Wal-Mart and see plenty of consumer products that
don't even come close to meeting Part 15 specs. Just pick up any touch lamp
and see. Admittedly there are a lot more products being sold today than
ever before, but if laws are not enforced they do no good.
