摘要： A method is provided for reducing interferences in communications exchanged along a plurality of communication channels extending between a DSLAM and subscribers' terminals. The method comprises i) storing a mathematical representation of the plurality of communication channels; ii) measuring at least one parameter characterizing a first communication channel; iii) applying the measured parameter(s) to update the mathematical representation of the first communication channel if required and replacing the mathematical representation of the first communication channel with the updated mathematical representation thereof. At times when communications are exchanged along that first communication channel, applying updated mathematical representations of the first communication channel together with most recent mathematical representations available of one or more other communication channels that are physically adjacent to the first communication channel in order to estimate expected interferences in communications to be exchanged along that first communication channel, modifying at least one operating parameter of the first communication channel in response to said estimation; and repeating the former steps for at least one other communication channel.

摘要： A method for dynamically adding a new channel to a group of virtually concatenated channels carrying traffic to a network element (NE) of a synchronous network. By this method if a delay associated with the new channel is longer than a delay associated with the group of virtually concatenated channels then traffic received along the group of virtually concatenated channels is delayed until the group of virtually concatenated channels and the new channel are time-aligned, and then the new channel is added to the group. If the delay associated with the new channel is shorter than the delay associated with the group of virtually concatenated channels then traffic in the new channel is delayed until the new channel and the group of virtually concatenated channels are time-aligned, and then the new channel will be added to the group.

摘要： A smooth connector circuit for on-line connection of an optical telecommunication module to a main telecommunication unit, where the main unit comprises a common power supply circuit and is connectable to a number of optical telecommunication modules by separately creating with each of them a power connection, a control connection and a communication connection. When inserting an optical module to the main unit, the proposed smooth connector circuit is capable of successively creating the mentioned connections between the optical module and the main unit, so that the power connection is created first and established gradually.

摘要： A method and a generator are described for high speed generation of an S-bit long pattern of a PRBS sequence to be periodically burst on to a bus of width S. The technique provides the calculation time being independent from the width S of the bus, and comprises calculation of all S bits of the PRBS pattern separately and in parallel by using previous PRBS patterns stored in a memory. For each bit to be generated, the generator performs a constant number N of logical operations require(by a polynomial defining the PRBS sequence.

摘要： The invention proposes a technique for measuring chromatic dispersion in an optical communication line transmitting an optical signal at a predetermined optical wavelength. The technique comprises determining the sign of chromatic dispersion and includes introducing controlled changes of wavelength around the predetermined wavelength, monitoring the optical signal that has passed said line, and obtaining a first and a second signals, wherein the first signal reflects changes of the carrier wavelength, and the second signal reflects changes of delay of the optical signal transmitted via the line. The two signals are compared and the chromatic dispersion sign is determined based on the phase difference there-between.
