Next Generation Network Plan Page 5 two Piber strands to each NSCC site to provide network connectivity. For this design, six fiber strands are proposed to each site to prnvide a€��tional fiber capacity for future network b owth and applications. For the NSCC network, CTC identified 108 primary sites in Ehe NSCC for connectivity to the fiber optic network during the f�'sL phase of construction, based on site information provided by the NSCC and its members. The list of sites is provided in Appendix B. On average, each site was approximately 03 miles from the backbone ring for a total of appro�mately 35 miles of lateral construction. 1.2.1.2 Recommended Electronic Architecture: Gigabit Ethernet The NSCC uses Gigabit Ethernet electronics in the fiber portion of the I-Net. CTC recommends that the NSCC members continue use of Gigabit Ethernet electronics to light the fiber in light of growing trends in wide area networking and the existing networking equipment currently used by the NSCC. Gigabit �.511�lr�� L� technology provides a relatively low cost and simple method of providing lligh capacity connectivity to users over the fiber a��ic n��wazk. It is a state-of-the-art, standards-based technology that is well-defined, mature, offers competitive hardware pricing and is the focus of continued hardware platform research and development. As proposed, the network will deliver 1 Gbps access to 14 sites with the remaining equipped at 10 M�bps. The design also allows upgrading �e capacity at each site. This transmission capacity is well in excess of the standard speed available over leased T1 li�;•; •' 1.2.1.3 Operational Considerations: Wholesale versus Service Models Given the proposed design of the network, CTC recommends two possible operations models based on available network resources and the needs of the NSCC entities. The first operations model is a wholesale or broker model. Network resources are assigned to various uses and the user is responsible for monitoring, managing, and maintaining network resources. The second model is a service provider model. The central entity or several entities provide networking services over the NSCC network to end users and handle the maintenance and operations of the network. � r } Delivers 1,000,000,000 �its-per-seeond, ;.e. iGbps or gigabit � 7j circuits (which provide band�ic�sh of 1.54 Mbps) are commonly used to connect community facilities. A typical concern is not with the cost of ; T circuits, but the performance and capacity iirnits that cons�-ain applications and data exchange. all text and diagrams C�3 Ci'C 2007
