Abstract

A multiservice private network and interface modules (M1-M5). Each of said modules is dedicated to interfacing a specific terminal equipment (T1-T4, GTW; 310-380) in the multiservice private network. The interface modules (M1-M5) are connected to the terminal equipment on a one-to-one basis. Each interface module (M1-M5) is configured to send and/or receive data in a format adapted to the terminal equipment to which it is connected, at a specific wavelength, in order to interconnect, via said private network, at least two mutually compatible terminal equipments among all the terminal equipments. This arrangement is typically applicable in particular to interconnecting, via a common network, heterogeneous different terminal equipments, so that the mutually compatible terminals communicate directly with one another without interfering with communication between other terminals of a different type.

Claims

1. A multiservice private network comprising access points and destination points to which N terminal equipments (T1-T4, GTW;

310-380) are connected, said private network being configured to effect a summation of all signals injected at each access point and then broadcast that summation to all destination points, the signals summed and broadcast taking the form of a wavelength division multiplex (WDM), characterized in that N interface modules (M1-M5;

M10-M80) are connected on a one-to-one basis to the N terminal equipments, each of said N interface modules (M1-M5;

M10-M80) being adapted to send and/or receive data in a format appropriate to the terminal equipment that is connected to it, said format being particular to a specific wavelength (λ

i), in order to interconnect via said private network at least two mutually compatible terminal equipments among said N terminal equipments.

2. The network according to claim 1, characterized in that each interface module (M1-M5;

M10-M80) comprises an electronic processing area (Z1) for transposing the signal delivered by the terminal equipment into a signal adapted to the constrains of its transmission by said private network or, conversely, to transpose a signal carried by said private network into a signal comprehensible to the terminal equipment if said signal is intended for it, and an optical processing area (Z2) for sending and/or receiving said signal at a specific wavelength.

3. An interface module adapted to be connected to a terminal equipment (T1-T4, GTW;

310-380) of a multiservice private network, characterized in that the interface module is adapted to send and/or receive data in a format that is appropriate to said terminal equipment (T1-T4, GTW;

310-380) and in particular to a specific wavelength (λ

i), in order to enable interconnection via said multiservice private network of said terminal equipment and at least one mutually compatible terminal equipment among N other terminal equipments.

4. An interface module according to claim 3, characterized in that the interface module comprises:

a send data formatting unit (MFDe) adapted to adapt signals coming from the terminal equipment (T1-T4, GTW;

310-380) that is connected to it and to transform them into a signal adapted to the constraints of transmission by said private network;

control electronics (ECEO) for receiving the signal processed by the send data formatting unit (MFDe) and adapted to control an optical sender (EO) for sending said signal at a specific wavelength (λ

i);

an optical receiver (RO) for selecting and detecting, from a set of signals of a wavelength division multiplex, a signal at a specific wavelength (λ

i) intended for the terminal equipment (T1-T4, GTW;

310-380) that is connected to it;

receive electronics (ER) adapted to transform the electrical signal from the optical receiver (RO) into an electrical signal compatible with

a receive data formatting unit (MFDr) adapted to convert the signal coming from the receive electronics (ER) into a signal comprehensible to the terminal equipment (T1-T4, GTW;

310-380) that is connected to it.

5. An interface module according to claim 4, characterized in that the send data formatting unit (MFDe) and the control electronics (ECEO) form a send interface (IES), the receive data formatting unit (MFDr) and the receive electronics (ER) form a receive interface (IRS), and said module is formed of an appropriate assembly of a send interface (IES), a receive interface (IRS), an optical sender (EO) and an optical receiver (RO) adapted to the application to which it is dedicated.
