DocID025446 Rev 3

The ascending and descending data rates shall be coded as described in Table 50.

When the SRTAG2K-D is able to change both data rates, it returns the following response.

The data rate of this response is 106 kbps; then, the SRTAG2K-D changes the ascending

and descending data rates.

Table 51

gives the details sof the PPS response.
