摘要： A method of configuring an optical network terminal, ONT, of a wavelength division multiplexed passive optical network, WDM PON. Sequentially setting a transmission wavelength of a tunable optical filter at the ONT to one or more wavelengths of a pre-selected plurality of transmission wavelengths until a wavelength is identified for which no downstream optical signal from an optical line terminal of the WDM PON is detected. Determining whether a transmitter operable at said identified transmission wavelength is present at the OLT and is available to be assigned to communicate with the ONT. If a transmitter is determined to be present and available, maintaining the transmission wavelength of the tunable optical filter at transmission wavelength and assigning the ONT to the OLT as a subscriber at said identified transmission wavelength. If a transmitter is determined to be one of not present and not available, recommencing the method.

摘要： A method for measuring asymmetry in propagation delay of first and second links which connect a first node to a second node of a communication network. The method comprises measuring (101) a round trip delay of the first link. The round trip delay can be measured by transmitting (102) a test signal from the first node to the second node over the first link and receiving a reply to the test signal from the second node over the first link. The method further comprises measuring (105) a round trip delay of the second link. The round trip delay can be measured by transmitting (106) a test signal to the second node over the second link and receiving a reply to the test signal from the second node over the second link. A difference in the propagation delay of the first link with respect to the second link is determined (109) using the measured round trip delays of the first link and the second link.
