If the modem doesn't recognise service tones, there are restrictions on
dialing out that are more retrictive than if the modem does support service
tone recognition.

Austel TS 002 seems to lump service tone detection as an "all or
nothing" kind of thing - if the modem doesn't detect all service
tones, it can't claim service tone detection.
