Common use of Network Architecture Clause in Contracts

Network Architecture. (i) Hubs and Lit Buildings communicate via multiple DS3/DS1 radio links in the 38-40 Ghz portion of the spectrum. The Hubs function as concentrators for these milliwave links, providing DS3 or DS1 service for Lit Buildings within the Hub service area. The traffic from the Lit Buildings will be bundled into multiple DS3 links over a fiber SONET ring backbone, or connected by lower frequency radio shots (i.e., 18 and 23 Ghz currently and 6 and 11 Ghz in the future). (ii) The network architecture features Lit Buildings as customer access points for traffic, with Hubs transmitting and receiving traffic from Lit Buildings via milliwave links. Hubs concentrate, transmit and receive that traffic over fiber links to central office switch sites, other Hubs and points of collocation (each a point of presence).
