The outside plant includes substantial network capability distributed between two wirecenters. Each exhibit hall is one wircenter and contains central infrastructure as well as distribution cabling. The wirecenters are linked in a centra/remote architecture, with the remote being fed by 2 T1 circuits and a 1000BaseSX circuit.
Using the advanced capabilities of the Shady Rate Interface, some exhibitor circuits "loop through" other customer premises. These circuits are on existing trunk infrastructure, but are not present on the interface equipment at these customer sites.
