The Newton Manufacturing Company has three facilities that are located in Columbia, South Carolina. The corporate office is located in an 11-story building downtown. The R&D facility is located on the north side of the city approximately 4 miles (6.4 km) from the corporate office in a five-story building. The manufacturing facility is located approximately 6 miles (9.6 km) to the northwest of the corporate office. Line of sight exists from the downtown office to all facilities. Users at the manufacturing plant require network connectivity for file-sharing and e-mail, while the users at the R&D facility require high-speed Internet access with the ability to send large CAD drawings to the corporate office and large machine control files to the manufacturing facility. Presently, the manufacturing facility is connected to the corporate office by a 64-kbps leased line, and the R&D facility is connected to both the corporate office and the manufacturing facility by a dedicated T1 line. The company plans to add a second line of development at the R&D facility within the next 60 days. The current T1 lines are at a constant 70 percent utilization rate. The current projected lead time for installation of additional lines is 90 days if the cable plant will support it. Which deployment option would provide the most benefit to the customer?
point-to-point link from corporate to manufacturing, and a point-to-point link from corporate to R&D
