Abstract: A network element that is capable facilitating the routing and accounting of messages between a plurality of network elements that do not share a common signaling application protocol nor a common transport protocol suite. In one embodiment of the present invention, a Multi-Protocol Gateway (MPG) is adapted to receive a signaling message and subsequently translate both the signaling and transport protocol suite prior to message routing. The MPG node is also configured to create and maintain usage and measurements data that may subsequently be used to produce billing records.

Abstract: A distributed gateway includes distributed gateway routing elements co-located with SS7 network elements. Each distributed gateway routing element performs an SS7 routing function, such an MTP level 3 routing function. The distributed gateway routing elements communicate with each other over a virtual bus that guarantees quality of service for SS7 message packets. Accordingly, the distributed gateway routing elements set quality of service parameters in the SS7 message packets that are forwarded over the virtual bus.

Abstract: A camera housing assembly for protecting a camera from potentially-damaging environmental conditions, such as high temperatures, humidity and corrosive air-borne particulates, has a housing and an internal heat sink received within the housing. The internal heat sink defines a hollow body extending in the elongated direction of the housing and forming an internal chamber for receiving the camera and for transferring heat away from the chamber and camera. A polymeric insulating material is disposed within an annular space formed between the internal heat sink and housing in order to thermally insulate the internal heat sink from the housing. A thermoelectric cooling device extends through an aperture formed in a wall of the housing, and is thermally coupled between the internal heat sink and an external heat sink mounted to an external wall of the housing for transferring heat from the internal heat sink to the external heat sink.
