The City of Ames needed a network to support supervisory control and data acquisition (SCADA) and protective relaying for their municipal electric utility. Burns & McDonnell designed a SONET ring system using GE Junglemux equipment. Ethernet, voice and digital serial connectivity is transported through the network for utility operations.

The city’s pilot wire relays were upgraded, and an ADSS fiber optic cable plant was installed to 12 substations and the operations center. The cable was routed on both overhead poles and in underground conduits using directional boring.

The SONET network uses OC-3 over the optical fiber between substations and the city’s control center, providing a secure, integrated network to support utility substation communications.
