Abstract: A network access optimization modeling initiative (NAOMI) that enables the operating personnel of a wide area service provider to configure the trunk connections of a telecommunications access network so as to gain access to the end offices of local area access providers at a given level of performance at minimal cost. Upon request, NAOMI optimizes the direct end office trunk and tandem trunk connections between the serving wire center (SWC) to which a wide area service provider gains access to a local area access provider and the end offices to which long distance calls are directed. In operation, NAOMI first obtains a configuration of the access network so that the respective positions of the points-of-presence (POPs) of the wide area service provider, tandem switches, end offices and various direct end office trunks (DEOTs) and tandem trunks of the access network are known.

Abstract: A vehicular surveillance system comprising a video recorder and monitor in a housing mounted within the passenger compartment of the vehicle to a bracket and a small camera rotatably mounted to the windshield of the vehicle. An FM microphone transmits audio signals to the vehicle's antenna whence it is carried to the recorder by a cable and added to the video images. Date and time information is superimposed on the video image on the top right of the image so as to interfere as little as possible with the image being recorded. The video recorder has a locking mechanism to prevent ejecting the video cassette by unauthorized personnel and its on/off switch is combined with the start record/stop recording function so that one button applies power to the system and starts the recording after a short delay. The housing may be removed from the vehicle for portable use in presenting recorded events as evidence and both video recorder and monitor may operate on the car battery or standard household current.
