Radio over IP

Radio communications systems must provide maximum reliability and seamless integration across multiple products in the network. Radio over IP (RoIP) solutions provide stable, high quality voice audio, and maximum system reliability in critical network connectivity applications. TC Communications specializes in communications for critical networks, namely 2 and 4-wire analog radio over IP and Ethernet networks.

Here are a few popular applications:

  • Providing stable, high quality voice, audio and system reliability between Emergency Dispatch Centers and remote radio transmitters and receivers
  • Linking 2-way radio systems to a Voter at radio control centers providing Ethernet, Analog and Dry Contact connectivity in one chassis
  • Replacing existing copper or leased lines with fiber optic connectivity devices to guarantee channel clarity, extend transmission distances and prevent signal loss due to degradation of traditional copper


The TC3846-6 supports voice bandwidths from 300Hz to 3.4KH. It can also be used to link or extend other types of analog, audio and intercom devices such as Frequency Shift Keying (FSK) modems, E&M, teleprotection relay controllers and dry contacts over Layer 2/3 IP networks.

As with all JumboSwitch® products it features hot-swappable interface cards, offers fiber optic and power redundancy, and is available in extreme temperature versions.

Specializations and Applications

Voting Comparator over IP

Many public safety networks rely on Voters to monitor multiple remote sites and select the receiver with the best audio quality. Moving to IP radios would require a complete equipment overhaul and training.

The TC3846-6 is able to connect the 600 ohm Analog and Dry Contact from the radio receivers at each tower. Through the support of the fiber optic ring or Ethernet network, the JumboSwitch® at the Central Office can hand off SNV-12 Voter/Comparator signals where it would then pick up the clearest radio signal from the field radios and pass it to the intercom.

Radio over IP will help network managers migrate their analog radios and voting comparators to an IP network. Because of the uncompressed full 64kbps signal sound will be clearer on the new network.

Leased Line Alternatives

As Telcos look to end services on copper leased lines, companies are looking for alternatives. Using RoIP network managers can preserve existing analog devices while moving to an IP network. These networks tend to be more cost effective, easier to maintain, and are often owned internally.

ESRN Eliminates Leased Line Costs

East Shore Radio Network (ESRN) needed a replacement solution to eliminate their leased line costs. Support for leased lines had also lessened in recent years. Finding a cost-effective and future proof solution was critical. ESRN was able to fully integrate existing equipment while improving audio quality.

"Over the past thirty-five years I have used similar boxes from other vendors for similar applications. But I have never seen one that would produce such a linear, uniform audio transmission from one end to the other - especially across an IP link.”
