| Description : Handles the internal signal SIG_KER_RT_PARAMETERS_REQ
|               This signal sets new start values for the three multiplexer

|               T1 - acknowledgement timer (in units of 10 ms)
|               T2 - response timer for multiplexer control channel
|                    (in units of 10 ms)
|               T3 - wake-up response timer (in seconds)
|
| Parameters  : t1 - new start value of timer T1
|               t2 - new start value of timer T2
