摘要： A method and apparatus for controlling DC balance in a digital communication system in which data frames (11) arc transmitted, wherein the data frames include a header portion (12) that is transmitted unscrambled and a pay toad portion (13) that is scrambled before transmission. The header portion includes a frame counter field (16) A value for the frame counter field is randomly generated (22) and an effect on the DC balance is estimated (23 ). It is then determined (24) whether the estimated effect on the DC balance meets defined requirements for DC balance, When the estimated effect does not meet the defined requirements for DC balance, a new random value for the frame counter field is generated and checked When the estimated effect meets the requirements, the randomly generated value is utilized (26) in the frame counter field in transmitted data frames.

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： A first end terminal and a second end terminal, as well as a respective method therein, are provided for enabling communication between the first end terminal and the second end terminal in a fibre optic access network. When the first and the second end terminal wish to communicate with each other, they first initiate a synchronisation procedure with the other end terminal for synchronising the two terminals with each other and enabling them to start a negotiation procedure. Then they perform the negotiation procedure,which pertains to a transmission rate for communication on the fibre link between the two end terminals, and they execute communication to the other end terminal employing the negotiated transmission rate.
