摘要： The present invention relates to a method, device and system for fast protection of an optical network system, in particular for a Passive Optical Network (PON), such as a Gigabit-capable Passive Optical Network (GPON). In the method, communication failure between a first optical network device and a first optical line termination device is detected. Switching of functionality from the first optical line termination device to a second optical line termination device is initiated, and a control message is sent from the second optical line termination device to the first optical network device such that the first optical network device is prevented from moving into initial state. Furthermore, the method comprises determining and setting timing settings for the first optical network device.

摘要： Disclosed is a method performed by a radio unit (10) operable in a base station system of a wireless communication network, for reducing interference at the RU. The base station system comprises a baseband unit (30) the radio unit (10) and a plurality of radio heads (21-26) wherein the radio unit is connected to the plurality of radio heads via a number of metallic conductors (40), and wherein a signal is to be communicated to the radio unit at a first frequency range over one of the number of metallic conductors from one of the plurality of radio heads. The method comprises: detecting (206) if there is any near end crosstalk, NEXT, at a receiver of the RU, the receiver being connected to the one of the number of metallic conductors, and, when NEXT is detected, triggering (210) the one of the plurality of RHs to send the signal to be communicated over the one of the number of metallic conductors at a second frequency range different from the first frequency range where a lower NEXT is expected than at the first frequency range. Disclosed are also a corresponding radio unit and a computer program.

摘要： Methods and nodes for providing radio access to a communication network (314) for mobile terminals (T) at a local site (300). When a local transition unit (304) at the local site receives incoming signals from an antenna (302a) and associated radio head (302b) installed at the local site, the signals are converted into optical form and the local transition unit sends the signals in optical form over an optical link (306) to a central office (308) comprising a set of radio units (312). A central transition unit (310) at the central office converts the signals into a form adapted for reception by a radio unit. The central transition unit is further instructed by a control unit (316) to forward the signals to one of the radio units based on configuration data of the antenna/radio head. The configuration data has been registered at the control unit when received from the antenna/radio head over a control channel automatically at installation. The central transition unit accordingly forwards the signals according to the instruction from the control unit to the correct radio unit for processing in digital format and digital transmission over the communication network.
