ABSTRACT:
The present invention discloses a device and method for implementing multi-port service convergence. The device at least comprises a clock & data recovery module, a encapsulating module, a mapping module, a de-mapping module and a decapsulating module, and further comprises at least one branch clock generating and adjusting module for determining transmitting clock frequency information of decapsulated service data and adjusting local branch clock frequency based on the transmitting clock frequency. In the method according to the present invention, firstly the transmitting clock frequency information of service data is extracted, then the service data is transparently encapsulated, the encapsulated data packets are mapped and transmitted; then the received data packets are de-mapped, the de-mapped data packets are decapsulated; the transmitting clock frequency information of the decapsulated service data is determined, and local branch clock frequency is adjusted according to the transmitting clock frequency; at last branch service data is received in terms of the adjusted local branch clock frequency.
