    Abstract: A housing for receiving printed circuit boards whose components form at least parts of a communication system, comprising a housing cover and a connection area which is accessible from the outside. A main printed circuit board is arranged between the base housing part and a cover part. Plug-in devices for at least one extension printed circuit board are provided in an extension area of the main printed circuit board. A first hood is provided in order to cover the extension area. The hood has push-through openings arranged towards the connection area, corresponding to plug-in devices on at least one extension printed circuit board in an assembled state. The first hood can engage with the cover part by means of a lock connection whereby said lock connection can only be released using a tool.

    Abstract: A chassis and associated telecommunication circuit card are disclosed. The chassis has heat dissipation and flame containment features while accommodating a high density of the circuitry cards. Embodiments include an inner housing with a double-layer middle floor dividing the chassis into top and bottom chambers. Each layer has partially aligned slots, and an air gap is provided between the two layers. Embodiments also include a double-layer mesh cover with an air gap existing between the two mesh layers. Projections and grooves are provided on the inner surfaces of the inner housing to receive circuit cards having a guide on one edge and a fin on another. The circuit card includes conductor structures such as multiple board layers with paired and segregated conductors. The circuit card also includes some components positioned to cooperate with the ventilation features of the chassis and includes some components chosen for low-power consumption or reduced flammability.
