Extensive Industry Applications

Analog Radio over IP/MPLS

  • Radio over IP/MPLS devices empower emergency dispatch centers to communicate with remote radio transmitters and receivers.

  • Two-way radio systems can link to a voter at radio control centers that provide Ethernet, analog, and dry contact using only one chassis.

  • Existing copper and leased lines can be replaced with fiber optic connect-able devices to guarantee channel clarity, extend transmission distances or prevent signal loss.

Voice, Analog and Data over Fiber

  • Replace expensive leased line phone circuits and deliver clean, consistent audio quality using fiber optic cable.

  • Supports voice bandwidth from 300Hz to 3.4KH and hot-swappable interface cards, along with fiber optic and power redundancy. Extreme temperature versions can also be used.

  • With zero line losses and simplified level settings, the multiplexer remains precise thanks to internally redundant transmit and receive functions. Optional fiber redundancy and path diversity keep the radio system protected from an outage due to individual component failure.

Multi-County Public Safety Agency Upgrades Microwave Radio Network

Faced with falling equipment reliability and weak vendor support, a public safety communications network in Iowa required a system-wide replacement to keep police, fire and emergency first-responders connected. Using TC Communications’ JumboSwitch® Multi-service Ethernet Platform, the agency achieved Ethernet port limiting, management and self-healing redundancy, and improved audio quality and network management.

In Their Words

“We were prepared to deal with some problems during the installation...and we did have a few...but the issues were with the existing equipment and weren't related to the JumboSwitch. It is very adaptable to other equipment in the network and all counties are pleased with the system’s service and reliability.”
- Tony Carpenter, Vice President at Calhoun Communications

“TC did a great job taking something that may have been a little bit over the threshold but still being able to process it and not dropping packets, not having the buffer under runs.”
