Claim 6:
7. A narrowband interference isolation method, comprising:
receiving, by a slave communication device and from a master communication device, a parameter of a narrowband interference signal or a coefficient of a first filter from a master communication device using an Ethernet operation, administration, and maintenance (OAM) frame, wherein the coefficient of the first filter is for filtering out the narrowband interference signal, the master communication device is connected to M slave communication devices, the slave communication device is one of the M slave communication devices, and M is an integer that is greater than 1; and
determining a coefficient of a second filter based on the parameter of the narrowband interference signal or the coefficient of the first filter, wherein the second filter is located at a receive end of the slave communication device, and the coefficient of the second filter is for filtering out the narrowband interference signal.
