Tone signals used in AlphaCom:

Timeslot Freq.         Level               Cadence               Tone
-------- -----  ------------------  --------------------   -----------------------------
  Ts 0   500Hz  2.5V  Peak-to-peak  Continous              Connection/disconnection tone
  Ts 1   400Hz  2.7V  Peak-to-peak  Continous              Dial tone
  Ts 2   500Hz  2.6V  Peak-to-peak   32 ms on,  32 ms off  Failure/ringing tone
  Ts 3   500Hz  0.45V Peak-to-peak  100 ms on, 100 ms off  Success tone, muted
  Ts 4   500Hz  2.6V  Peak-to-peak  100 ms on, 100 ms off  Success tone
  Ts 5   500Hz  0.5V  Peak-to-peak  200 ms on, 200 ms off  Busy tone, muted
  Ts 6   500Hz  2.7V  Peak-to-peak  200 ms on, 200 ms off  Busy tone
  Ts 7   533Hz  1.3V  Peak-to-peak  750 ms on,  12 ms off  Off-hook/handset dial tone

The signal levels was generated on an AMC board (MC 68000 based) and measured on an AGA output, terminated with 600 ohms onboard.
