[comp.dcom.telecom] Funny Ringing Tones in North America

Dave Leibold <Dave.Leibold@f135.n82.z89.onebdos.UUCP> (06/03/91)

Regarding the double ringing tone of numbers in 416-392, that prefix
is used by the City of Toronto for municipal services, and presumably
a DID connection to their PBX. 416-393 is for the Metro level of
government in Toronto. Thus, it's the PBX ringing tone that comes
across (and PBX rings are normally faster than your average phone
line).

Not too many years ago, when step-by-step switches dotted the Toronto
landscape, it was possible to get all kinds of error tones depending
on which exchange was dialed. There were sirens for wrong numbers or
invalid prefixes, or there were recordings, or there were many types
of fast busy signals to be had.

With the conversion of just about everything to DMS switches in Bell
Canada territory, everything will soon sound the same.
