Abstract: A retention mechanism for attaching equipment to a mounting rail comprises a slider including a first retention section and a pivoting lever mechanical coupled to the slider. The slider is movable in a translational manner along a sliding direction with respect to a remaining portion of the retention mechanism. The lever includes a second retention section aligned with the first retention section in the sliding direction. A reception area for receiving the mounting rail is defined between the first retention section and the second retention section.

Abstract: A method for testing speech/data channels in a telecommunication network port wherein existing test functionalities can still be used with respect to IP networks arranged at a transport side. The method includes the steps of integrating a test functionality into a media gateway controller, addressing a speech/data channel, which is connected to a gateway, by the test functionality, selecting the gateway that is closest to the addressed speech/data channel on the basis of a selection function implemented in the test functionality, and performing the test proceeding from this selected gateway.
