Abstract: The method comprises 10 processes. The 1st process waits  for a certain time (T1) checking the dialing state.  The  2nd  process checks a tone read port after T1 and determines the change  of  T1 period. If any, the 3rd process checks that T2 is low after taking 3 periods. The 4th process transacts as a counterpart responds  to the call when there is no change of T1 period and  above  T2.  The 5th process checks that the second "high" is T4 at T3  within  T2. The 6th process checks that the third "low" is T4 at T3.  The  7th process transacts as a counterpart responds to the call  when  the "low" is out of T4 at T3 and transacts as a ring-back tone or busy tone within T4 at T3. The  8th  process  checks  that  the  second "high" is T6 at T5. The 9th process checks that the  second  "low" is T8 at T7. The 10th process transacts as a counterpart  responds to the call when it is out of T6 at T5 or T8 at T7  and  transacts as a ring-back tone within T7-T8.

Abstract: To improve the power efficiency by supplying the oil into the torque converter, this unit is so constituted that the pressure sensor(PS) is installed to detect the operation pressure on the third line(3) providing the oil pressure while the damper clutch(DC) is operated through the damper clutch control valve(DCCV), and this pressure sensor feeds the detection signal to TCU and in case the operation pressure is not optimum, the damper clutch control solenoid valve(DCCSV) is controlled to compensate the optimum oil pressure.
