Since ROLM systems don't use standard tones, I'm trying to find a list of the frequencies they use. Does anyone know off hand dialtone, confirmation tone, etc....or have a PDF of a manual that would list them?

Dialtone is 480hz -17 dBm0
Confirmation tone is 440hz -13 dBm0
And remember that the Rolm's ran at 12 bytes.
And all this depends upon when your system was built. I have never seen a .pdf for it but we did have a manual at one time.

Off the top of my head dial tone is 620 X 480, which is typically a busy signal. Standard dial tone I believe is 350 X 440.
