Notes
1. If a setting is not required, store FF in the address.
2. Tone frequencies are stored as look-up tables in hex code. For each pa-
rameter, there is a look-up table for each country that uses it. The tables
are given following this page. For each parameter, do not input a RAM
value that is not included in the table. FF[H] = disabled.
3. Pulse dial parameters (addresses BRO: 807F4A to 807F4F, BR1: 00674A
to 00674F) are the values for 10 pps. If 20 pps is used, the machine auto-
matically 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:
High frequency tone: - 0.5 x N
807F52/807F54
dBm;BRO
- 0.5 x N
006752/006754
dBm;BR1
Low frequency tone: - 0.5 x (N
807F52/807F54
+ N
807F53
) dBm ; BRO
- 0.5 x (N
006752/006754
+ N
006753
) dBm ; BR1
Note: N
807F52
, for example, means the value stored in address 807F52[H]
