Our Role in Power Utility
Communications

Connection is important. When utility networks need reliable telecommunications solutions, TC Communications is there to provide top-notch products. With a focus on preserving the strength and reliability of legacy networks, TC technology integrates traditional interfaces into one Ethernet/IP ready platform. Whether managing a heavy power grid or conducting remote management TC’s telecommunications products will get the job done.

Specializations and Applications

Teleprotection with TDM over IP Technology

Experience low latency, dependability, and security within utility communication network design. Make sure the signals that manage power grid load and protect equipment are consistent using JumboSwitch technology. Legacy equipment that includes Ethernet, GigE fiber ports, Turbo Serial, VoIP+, virtual PBX are all compatible. Get the most out of legacy equipment that does not suffer from latency faults or failed signals when migrating to IP.

Applications:

Low-latency Serial Between Protective Relays

Isolating Substations From The IP Network Using Serial Over T1

SCADA Applications

Supervisory control and data acquisition (SCADA) is essential to support real-time communications. Utilizing a modern IP platform the JumboSwitch offers a complete solution to monitor network applications and identify abnormal conditions. Since the beginning, TC has been testing and implementing SCADA technology for power utilities. Customers can trust that networks will be a cinch to monitor.

Applications:

Serial Server & Serial-To-Ethernet Conversions

Point To Point Multi-Interface Fiber Optic Multiplexer

Legacy Network Modernization

Expiring or expensive 4-wire Analog and T1 leased lines are nudging utility companies to consider alternatives. It’s possible to use existing fiber and microwave IP/MPLS networks to connect Analog and T1/E1 equipment. TC products provide comprehensive support for existing legacy networks as well as gradual shifts to Ethernet/IP. Legacy devices and JumboSwitch products offer flexible connectivity options. This includes the latest in Ethernet-over-PDH technology including Ethernet over T1/E1, Ethernet over T3/E3 and Ethernet over OC-3/STM-1. More information about leased line replacement.

Applications:

Extending Ethernet LANs Over Existing T1/E1 Or PDH Networks

Preserve Legacy Devices While Utilizing Your IP Network

A History of Helping
Customers Succeed

Since the beginning, TC has focused on bridging legacy service with IP/Ethernet and enabling communication between devices. In the founding years TC worked alongside the Department of Water Resources. Together they brought fiber connectivity to SCADA applications. Since then plans have expanded to many critical utility applications including Teleprotection and substation communications.
