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

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
