Re: Remember System X?
"[...] System X, devloped just so that any call could be tapped automatically and remotely. Noone else in the world thought this an acceptable idea so it didn't sell."
?
The globally deployed "mass snooping" capability underlying much of this fuss is known in the trade as "lawful interception" (sometimes "legal interception", sometimes "wiretap" instead of interception, etc).
It is not specific to System X, and has been a routine part of any telecom vendor's core voice network equipment and capabilities for ages.
Today's digital technology allows lawful interception to work on a much broader scale than back in the olden days of System X
Now, where were we?
