Abstract: A jack and chassis assembly includes a baluns interface connected directly to the in/out wire wrap pins on the jacks. This helps to convert 75 ohm coaxial signals to 120 ohm twisted pair interface signals for equipment connections. The jack and chassis assembly includes at least one jack, a chassis defining a first frame holding the jack, a circuit board mounted to the first frame and in electrical contact with the jack, and a balun in electrical contact with the jack. Methods for assembling a jack and chassis assembly include mounting a jack onto a frame, providing a second frame holding a balun, and connecting the jack to the balun. A chassis assembly includes a first frame, and a second frame, with the first frame being mounted within the second frame. A method for servicing a jack assembly includes providing jacks mounted in a first frame in a chassis, providing a circuit board secured to the first frame and in electrical connection with each of the jacks, removing the first frame holding the jacks from a second frame supporting a panel of baluns electrically connected to the jacks, and providing a space between the plurality of jacks and the panel of baluns sufficient to permit service access to the jacks.

Abstract: A telecommunications device including a plurality of splitter cards mounted in a chassis. The device also includes a circuit board and plurality of card edge connectors for providing electrical connections between the splitter cards and the circuit board. The device further includes POTS connectors, LINE connectors and DATA connectors. The circuit board includes a first layer having first tracings that electrically connect contacts of at least one of the POTS, LINE or DATA connectors to at least one of the card edge connectors; a second layer having second tracings that electrically connect contacts of at least one of the POTS, LINE or DATA connectors to at least one of the card edge connectors; and a third layer having third tracings that electrically connect contacts of at least one of the POTS, LINE or DATA connectors to at least one of the card edge connectors. The second layer is positioned between the first and third layers. A majority of the second layer is covered by a grounding plane. The grounding plane and the second tracings are co-planar such that the grounding plane adds no additional thickness to the second layer. The grounding plane is positioned between the first and third tracings to reduce cross-talk between the first and third tracings.

Abstract: A transmission apparatus which is capable of maintaining excellent EMC performances even if the number of cables to be connected thereto is increased. An electronic circuit unit is plugged into a subrack from the front of the subrack. A connector unit-receiving block is arranged on the rear surface of the subrack. A connector unit connectable with an external cable to be connected to the electronic circuit unit is plugged into the rear of the subrack at the rear of the electronic circuit unit, for being received within the connector unit-receiving block. The connector unit is configured such that a metal shield case covers a connector board having a connector mounted thereon.
