Specifications include, but are not limited to: a) The preliminary network design will enable the deployment of the following services: i. Telephone services for commercial / industrial users. ii. Internet services, including at least 1 Gbps to every customer. iii. Bandwidth on Demand. iv. Other services that may be needed by residential or business customers within the service territory. b) Design will be a passive optical network utilizing GPON. Design alternatives for nextgeneration PON (NG-PON2 and/or XGS-PON) will be provided along with anticipated schedules and cost estimates where knowable. An understanding of network trends affecting Siloam Springs’ investment horizon will be included for these next generation typologies. c) Wherever technically feasible, the design will integrate software defined networking (SDN) and network function virtualization (NFV). If SDN/NFV is not technically feasible for initial deployment, the network design will allow for SDN/NFV deployment at some point in the future.
