NOTES
1. If a setting is not required, store FF in the address.
2. Italy and Belgium only
RAM address 68055E: the lower four bits have the following meaning.
Bit 2 - 1: International dial tone cadence detection enabled (Belgium)
Bit 1 - Not used
Bit 0 - 1: PSTN dial tone cadence detection enabled (Italy)
If bit 0 or bit 2 is set to 1, the functions of the following RAM addresses are changed.
680508 (if bit 0 = 1) or 680538 (if bit 2 = 1): tolerance for on or off state
duration (%), and number of cycles required for detection, coded as in address 680533.
68050B (if bit 0 = 1) or 68053B (if bit 2 = 1): on time, hex code (unit = 20 ms)
68050C (if bit 0 = 1) or 68053C (if bit 2 = 1): off time, hex code (unit = 20 ms)
3. Pulse dial parameters (addresses 68054A to 68054F) are the values for 10 pps. If 20 pps is
used, the machine automatically compensates.
4. The first ring may not be detected until 1 to 2.5 wavelengths after the time specified by this
parameter.
5. Tone signals which frequency is lower than 1500Hz (e.g., 800Hz tone for AI short protocol)
refer to the setting at 6805B5h. Tones which frequency is higher than 1500Hz refer to the
setting at 6805B6h.
