Patent ID: 8422612

Claim:
A communication apparatus that receives a signal through a line, more than one signal being transmitted through the line and each including a management signal of a bit rate A and a data signal of a bit rate A B, the communication apparatus comprising: a signal receiving unit that receives a signal including a management signal of the bit rate A and a data signal of the bit rate B; a signal regenerating unit that generates a first management signal of a bit rate C from the received management signal of the bit rate A, where C=A×N, N being a natural number; an identification phase synchronizing unit that synchronizes the first management signal of the bit rate C with the received management signal of the bit rate A; and a signal converting unit that analyzes the first management signal of the bit rate C, and creates a second management signal by converting N bits of the first management signal to one bit of the second management signal by majority decision.
