The CFU network is connected to the internet with multiple high-speed DS3 circuits to Sprint, AT&T, and other providers. These curcuits are capable of transmitting 45mb/s, for a total of 90mb/s. Additionaly, the CFU network can utilize a 100mb/s backup network connection to the internet. CFU also maintains peering arrangements with several local network providers giving both the ISP, and CFU, optimal access to other networks. Click on the image to left to see a larger version.

CFU Network in more detail

Data travels from our internet connections, through the routers and switches in our Network Operations Center (NOC), to the remote nodes via redundant fiber links, and then to the customer over our Coax Distribution Network. Commercial customers with Dedicated Fiber Connections are not transported over the Coax Distribution Network, but are transported from our NOC over the fiber network directly to their place of business.

CFU Internet Access

CFU utilizes SONET (Synchronous Optical Networks) technology to provide bullet-proof connections to the internet. The SONET rings that connect CFU to the rest of the world utilize high-speed switching. In the event of a fiber cut, the network is automatically switched to the protect path in under 50ms providing uninterrupted services. SONET provides a secure means of multiplexing voice, video, and data over a common path. Tellecommunications Carriers use SONET to carry their long distance traffic between Central Offices.
