Bits 7 – Energy saving for DSP, COMBLK, SiDAA
0: Does not save energy
1: Saves energy
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. The calculated level must be between 0 and 10.
The attenuation levels calculated from RAM data are:
