<p>In wideband filter installations and connections it is proposed to replace the conventional connection assembly for connecting the filter card (1') to the corresponding wiring (7), by a single strip (8) with closed contacts. This allows the size of the frame (5') to be significantly reduced and also allows the contact between the voice input and the corresponding output to be maintained in the event of a failure at the data input. In addition, the filter cards (1') preferably are individual cards, for a single user, allowing to install them one-by-one on a multiple strip as the number of users increases.</p> |
