A method for allocating a point-to-point channel to a user module of an optical communication network. The network includes user modules and optical terminations, and supports point-to-multipoint channels and a plurality of point-to-point channels, one same point-to-point channel being assigned to one single optical termination. The method is implemented for a user module called a requester user module, and includes: detecting a predetermined availability signal conveyed by a point-to-point channel of the plurality of point-to-point channels; and allocating the point-to-point channel over which the predetermined availability signal is conveyed, called available point-to-point channel, to the requester user module.

A processing of data for the management of the placement on standby of a client terminal connected to an operator terminal of an access network, the method comprising, in said client terminal, the following steps: a) determining a policy for placing the client terminal on standby, b) monitoring a client interface of said client terminal, disposed between said client terminal and a part of a local network situated downstream of said client terminal, c) monitoring an access network interface of said client terminal, disposed between said client terminal and said operator terminal.

Processing of data for the management of placement on standby

A method is provided for managing connections in an optical access network. Also provided are a corresponding platform, exchange, network and computer software product. The method manages connections of a plurality of user modules to a plurality of transmission modules of an exchange in an optical access network. The management method includes a dynamic re-arrangement of the connection of at least one of the user modules to at least one of the transmission modules according to at least one predetermined optimization criterion.

A method enables communication between a line termination device and at least one network termination device, the line termination device being connected by at least one line to the at least one network termination device. The method includes a step in which frames containing content data are transmitted by the line termination device via the line to at least one of the at least one network termination devices. Reconfiguration data is sent by the line termination device to at least one of the network termination devices, the reconfiguration data being specific to a communication protocol to be used for the transmission of the above-mentioned frames and enabling the reconfiguration of a modem of the destination network termination device.

Reconfiguration of network termination devices

The invention provides a portable and autonomous assistance device to derive information on faults in a private telecommunication installation comprising particularly equipment units to assist the client owning the installation in maintaining the latter. A maintenance session is selected in a maintenance server of the service provider managing the installation as a function of information transmitted by the assistance device so as to provide instructions in the device. The address of the server and an identifier of the equipment unit are rapidly read by means of a bar code reader which can also read bar codes in a user manual. The assistance device also serves to configure a terminal (TE) by means of a configuration session opened in a server (SFT) of the terminal manufacturer.

Maintenance system for a telecommunication installation

A broadcaster broadcasts all network cells received via a receive channel of a telecommunication line serving the installation to digital loops including terminals. A collector collects ATM cells produced by the terminals and transmits them in an emit channel of the line to the network. The broadcaster marks received network cells in order for the collector to eliminate them and not transmit them in the emit channel. ATM intercommunication cells can be produced by terminals and switched by the collector to the broadcaster in order to broadcast them with received network cells to destination terminals of the installation.

A method of setting up two-way optical communication between a central unit and a remote unit suitable for operating in a given communication mode selected from a plurality of communication modes. A plurality of frame patterns is defined in the central unit, with each frame pattern being appropriate to one of the communication modes. The plurality of frame patterns are sent sequentially until a coherent response is obtained from the remote unit, the communication mode of the remote unit being the mode which corresponds to the frame pattern which gave rise to the coherent response.

The synchronization of a terminal station in a half-duplex tree-structured communication network consists in counting clock pulses in a central station. The pulses are counted between the emission of a forward frame including a synchronization word emission order that is intended for the terminal station, and the reception of the synchronization word emitted from the terminal station in response to the forward frame. As a function of the pulse count is computed a delay depending on the propagation time between the two stations so as to data sectors emitted by the terminal stations do not overlaps and form a backward frame whatever the different distances between the terminal stations and the central station. According to the invention, the counted pulses are pulses of a central clock signal phase-shifted to within a bit time fraction of the received words. The time intervals attributed to the sectors are thus determined more accurately. The central clock signal depends on the operating rate of the terminal station, and the network can then carry multirate frames. The invention also remedies to variations of propagation time between the stations caused by thermal drifts by modifying clock signals to regenerate sectors in the central station.
