Notes : 1. In the case of V.29 or V.27, PRs and PRDETs bits are not active.

2. PNSUC s indicates the quality of the Rx signal that will give a ber of approximation of 1e

-5.

3. After sending the command SYNC0, all bits are reset.

4. When using long echo protection tone, otherwise 0.

5. When using short echo protection tone, otherwise 0.

6. STA-106 is set at the end of T6 and reset at the beginning of T10.

7. After sending the command SYNC1, this bit is set.
