摘要： An Optical Network Unit, ONU, and an Optical Line Terminal, OLT, as well as a respective method therein, are provided for enabling the ONU to communicate with the OLT. The ONU and at least one OLT are comprised in a passive fibre optic access network. The passive fibre optic access network comprises two fibre paths through the network, a main fibre path and a back-up fibre path, connecting the ONU with the OLT. When a fault is detected in the main fibre path is detected, transmission rate negotiation is performed between the ONU and the OLT over the back-up path. When a transmission rate is agreed upon between the ONU and the OLT during said transmission rate negotiation with regard to communication over the back-up path, the communication between the ONU and the OLT is executed using the agreed transmission rate over the back-up path.

摘要： It is an object of the present invention to provide switching equipment for communications networks, which switching equipment supports high-speed signalling between switch cards and line cards. Hence, the invention relates to a switching device for communications networks comprising a plurality of line cards and at least one switch card. The line cards comprise connection means arranged on or close to one edge of each line card, and the at least one switch card comprises matching connection means arranged on one flat side of said switch card. In this way, when said switch card is arranged substantially perpendicular to said line cards with said flat side of the switch card facing and at least partially overlapping said edges of the line cards, interconnection is achieved between the connection means of the line cards and the matching connection means of the at least one switch card.

摘要： A control device (13) for scheduling the transmission of signals from a plurality of transmitters (14, 15, 16, 17, 18, 19, 20, 21). The control device (13) comprises an evaluation element (22) arranged to determine the power level of the signals received from each of the transmitters and a scheduling element (23) adapted to determine a transmit schedule comprising the order that the plurality of transmitters should transmit based on the power levels of the signals received from the transmitters (14, 15, 16, 17, 18, 19, 20, 21). A method of operation and a node incorporating the control device is also disclosed.
