NSCC Executive Summary CBG Communications, Inc. <br /> channels, and aggregates the signals for the channels/entities that do their own playback. <br /> All of this access signal origination from CTV's Roseville facility is directly connected <br /> via fiber to the Comcast headend in Roseville through Comcast's Converged Regional <br /> Area Network(CRAN or C-RAN). The C-RAN is a regional interconnect used to <br /> transport all of Comcast's video, voice and Internet traffic around the Twin Cities to the <br /> various hub locations. This network is used, in the case of PEG programming, to <br /> transport services to the Roseville headend and the Shoreview hub for insertion onto the <br /> subscriber system serving the member cities. <br /> Beyond this, there are fiber I-Net connections from all of the local government members <br /> of the NSCC providing programming from their main City Hall locations, as well as fiber <br /> connections from the Roseville Schools, St. Anthony Schools and Moundsview Schools. <br /> Additionally, the HFC I-Net provides both frequent and occasional connectivity from a <br /> variety of locations throughout the NSCC area, including: Northwestern University, the <br /> Roseville Band Shell, Central Park and other locations. Both remote trucks also tie into <br /> the HFC I-Net to provide live signal origination from various locations throughout the <br /> NSCC area. <br /> Comcast provides access to an interconnect that utilizes infrastructure put in place as part <br /> of the C-RAN to provide the NSCC and other local franchise authorities to share video, <br /> voice and data services. This interconnect is commonly referred to as the PRISMA <br /> network. The equipment used to activate the network has a manufacture's name of <br /> PRISMA. Regarding the region-wide interconnect over the PRISMA system, CTV is a <br /> primary hub between various access entities throughout the Twin Cities area. This <br /> PRISMA interconnect system allows CTV to share programming(both send and receive) <br /> with these various entities. It also allows CTV to route around NASA programming, <br /> which is first downlinked at Comcast's Roseville headend and then provided through the <br /> dedicated CRAN fiber to CTV for further distribution across the interconnect. <br /> A review of these various signal transportation systems revealed the following <br /> concerning needs and interests for the future: <br /> xv <br />
