T200 Val This is the value of the T200 Acknowledgment timer divided by
two. The valid range for this field is 1 to 63 which translates to
T200 timer values of 2 to 126. 0 is not allowed and is an error. The
units of this timer are given by the T200 Res (resolution) field (see
below). Before configuring T200, you should read the description
of timer configuration at the beginning of this section.

LargeK value in the first option word is used. It is an error if both K
