Abstract:
A telecommunications device comprising:a plurality of splitter cards; a chassis including a card housing in which the splitter cards are mounted, the card housing defining an access opening for allowing the splitter cards to be inserted into or removed from the card housing; a circuit board that defines a backplane of the chassis; a plurality of card edge connectors for providing electrical connections between the splitter cards and the circuit board; POTS connectors, LINE connectors and DATA connectors; the circuit board including 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; the circuit board including 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; the circuit board including 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; and the second layer being positioned between the first and third layers, a majority of the second layer including a grounding plane that is co-planar with the second tracings such that the grounding plane adds no additional thickness to the second layer, the grounding plane being positioned between the first and third tracings to reduce cross-talk between the first and third tracings.
