Abstract: A Multiservice Access Concentrator (MAC) provides a time limit for a first ringing voltage signal in response to an attempted call. The call is attempted via a voice over packet-data-network system (VOPS), wherein the VOPS comprises voice over Internet Protocol (IP), voice over Frame Relay, voice over Asynchronous Transfer Mode (ATM), and voice over High-level Data Link Control (HDLC) network systems. Generation of the first ringing voltage signal is terminated upon expiration of the time limit. A control message is transmitted to terminate the attempted call, wherein the control message is transmitted via the VOPS.

Abstract: A controller controls a camera that produces a sequence of images and that has output coupled to a video encoder. The camera has an operating condition including a field of view and lighting, and one or more imaging parameters. The video encoder encodes images from the camera into codewords. The controller receives one or more encoding properties from the video encoder, and causes adjusting one or more of the imaging parameters based on at least one of the received encoding properties, such that the camera produces additional images of the sequence of images for the video encoder using the adjusted one or more imaging parameters.
