DOUBLE CHECK CALLS (AREA 3 TAB 28)
Value range 0-1, default 1.
By clearing this byte, the tone decoder will not restart from first tone-position until all telegrams
being checked have ended or failed. This could cause problems when there are tones sent
before the first tone, such as repeater start. In a system with many unstructured numbers and
many channels to scan, it could improve throughput to clear this flag.
Example:
The tone decoder shall restart from the first tone even if there are telegrams that haven't failed.
This is necessary for most systems to work, vital if repeater start codes can be included in the
telegrams.

TONLEN TAB (AREA 3 TAB 29 - 44)
Table with 16 entries.
This table makes it possible for the tone receiver to distinguish between 16 different tone lengths.
The content of this table is NOT changed automatically when changing the default tone system.
Each entry in the table has 3 ROWs with the following content:
- ROW 1: Flag:
0 = accept at end of tone if length within interval.
1 = accept as soon as length has reached min length, Max. length shall be set long,
exact value doesn't matter. Useful for repeater-start-code.
- ROW 2 : Min length (Normal timer concept, timebase 10 ms/100 ms)
- ROW 3 : Max. length
(Normal timer concept, timebase 10 ms/100 ms)
