Abstract: A method and device for sending a request (R) from a requesting machine (H) to a domain name server (1, 2, 3). A prior test of the validity of the destination telephone number (NTEL) of the request (R) is executed automatically and locally to the requesting machine (H) relative to a database (BD) local to said requesting machine (H) in order to forward the request (R) from the requesting machine (H) to the domain name server (1, 2, 3) only if its telephone number (NTEL) passes said test.

Abstract: A distribution frame for optical fibers comprises, for example, two elementary distribution frames in each of which supports are provided to support rows of optical fiber connection modules which, in an inclined rest position, are distributed in a matrix arrangement to connect ends of first optical fibers to ends of connecting optical fibers. To make a connection relating to a module supported by the support, the support rotates about a rotation shaft parallel to two sides of the matrix in a vertical plane, out of the mass of connecting optical fiber ends.
