Title: Optical transmission communication device and method
Inventor: ITO MASAAKI
IPC: H04B10/079
Filed: 2001-07-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical transmission communication device and a method, which are capable of cutting and dividing the wander problem that takes place the side of device facing. SOLUTION: A DMUX unit 1 generates and outputs toothless clocks and toothless data, having no data only at an overhead part. A DPLL 5 phase- controls a toothless clock part by the use of the inputted reference OSC and generates the smoothed clocks. A phase-monitoring unit 6 counts up, only when the write timing and read timing of memory are close to or far from each other in phase, and the count value is retained. The memory phase count value from the phase monitoring unit 6 is sent to a device control unit 7, and it is determined whether or not wander occurs, on the basis of the fact that the ratio of a positive-side count value to a negative-side count value is one to one. Therefore, it can be determined easily, without using a measurement equipment and a connection cable to measure wander whether or not wander is occurring.
