"With JumboSwitch, we could choose which substation, SCADA, AMR, telecommunication, office and security camera application we wanted to consolidate on the JumboSwitch network...I expect the JumboSwitch platform will provide communications for our core utility business and additional services, like T1, to customers for many years to come."

The Challenge: Upgrading and Consolidation
A Midwest Power Utility needed to upgrade its core communications network to transport various data and voice substation applications to remote sites. It also sought to consolidate AMR, teleprotection and telecommunication applications onto a single, common IP platform with transparent "on and off ramps."
The Utility had been using a combination of Ethernet, SONET and microwave for its communication network needs. However, it preferred an Ethernet migration path to achieve a more distributed throughput system (i.e., more bandwidth capacity), along with more simplicity and scalability.
The decision to upgrade the communications network presented the Utility with two options: Expand its existing SONET rings and install additional Ethernet cards, or upgrade the Ethernet network to a primary communications network.
Solution: Multi-service Primary Communications Network
The Utility moved forward with creating a primary communications network with a mesh topology based on the multiservice Ethernet capability of TC Communication’s JumboSwitch® Multi-Service gigabit Ethernet Switch.
The JumboSwitch solution provided an immediate migration path for moving existing applications over to IP. To implement these applications, the Utility network deployed 23 JumboSwitch nodes with four U chassis, each holding up to seven interface cards.
Moreover, the JumboSwitch’s ability to integrate IP, T1 over IP, VoIP and radio over IP (RoIP) significantly increased the Utility’s network’s flexibility and scalability for future applications.
Results: Configured, Tested, Commissioned
The new JumboSwitch network was configured, tested, and commissioned in just six weeks. This included, Bench Testing, Field Acceptance Testing (FAT), Site Acceptance Testing (SAT), all field installations and a 4-day hardware and TCView® Network Management Software training course.
Today, the system is fully operational and performing well.
