[comp.dcom.telecom] Telephone Tones Around the World

Rick Broadhead <YSAR1111@vm1.yorku.ca> (05/14/91)

As many of you know, ringing signals and busy signals vary from
country to coun try.  So do the tones a caller gets if all circuits
are busy.  Transit tones, t he tones which precede ringing, also
differ from one country to the next.
 
For example:
 
* Iceland's busy signal is a short sharp tone repeated at frequent
intervals.
 
* Bangladesh's ringing signal consists of two short tones repeated at regular
intervals.
 
* Tonga's ringing signal is a short tone followed by a longer pause.
 
My white pages directory used to provide this information, but it
hasn't been included the last few years.
 
Does anyone know where I could obtain a complete, country-by-country
list of telephone tones and signals?
 
If there's any reading available on the subject, I'd also welcome that
information, since I find the topic of telephone tones rather interesting.
 
Any information would be really appreciated.  Thanks!
