Common use of Network Architecture Clause in Contracts

Network Architecture. On-Net sites are customer access points for microwave links that transmit traffic to and from Hubs. Hub and On-Net sites communicate via multiple DS3/DS1 radio links in the 38 Ghz portion of the spectrum. The Hubs function as concentrators for these microwave links, providing DS3 or DS1 service for buildings within the Hub service area. In some instances , the traffic from these buildings will be bundled into multiple DS3 links over a fiber SONET Ring backbone, or connected by low frequency radio shots. This fiber backbone will initially be provided by a competitive access provider (CAP). In simple terms, the network architecture features On-Net sites as customer access points for traffic, with Hubs transmitting and receiving traffic from On-Net sites via microwave links. Hubs concentrate that traffic from On-Nets and transmit (or receive) traffic over fiber links to any one of the following:
