[comp.dcom.telecom] call waiting signaling

toml@uunet.UU.NET ( Tom Luteran ) (12/13/88)

     I am interested in finding information about the various
     call-waiting customer options that some local operating
     companies offer to their customers.

     What frequencies/durations of tones are used for
     this purpose?  Is there more than one way to do this
     (from personal experience, some systems "click" and
     some "beep" different number of times) and are
     there any "standard" ways?  Is there somewhere I can
     find this info?

     Thanks in advance.  I'll post a summary when I get
     responses.
