METHOD AND AN APPARATUS FOR MUTUALLY CONVERING DIFFERENT SIGNALLING SYSTEMS

摘要

If it is found that a dual transition has occurred in the received signal bits by comparing the current signal bits with newly received signal bits, a bit state analyzing means (10) puts an interrupt into a CPU. A current signal bit storing and converting means (20) is connected to the bit state analyzing means (10), and this current signal bit storing and converting means (20) stores a new bit state as the current bit state by receiving the new bit state from the bit state analyzing means (10). Further, the current signal bit state storing and converting means (20) converts the current bit state so as to be fit to the two signal method.
