Dangerous Radio
WAN Integration
Problem Solved!


img DCB's first PTT-24 installation has been in sevice over a year now improving safety and saving money. The PTT-24 Push-To-Talk Lockout Device monitors 24 incoming T1 lines for remote radio audio channels, protecting against possible loss of critical ground-to-air communications when there is a T1 problem.

When a T1 goes out of service, it's channels go busy. Since multiple ground sources coming in from different T1s vie for the same radios, the busied out T1 keys the radios, sometimes blocking all radio transmissions. The PTT-24 monitors incoming T1 lines. If one goes busy it is forced from a busy to a not-busy condition in 20 milliseconds, freeing up the radio system.

The PTT-24 went from initial specification to finished product in just one year, quite a feat for such a product. Check out the specs here for your critical distributed radio network installation.

DCB Products Enable ROIP Network


img Our long-time partner, Phase 4 Design (, received nation-wide commendation recently when one of their projects was highlighted in MissionCritical Communications Magazine. Phase 4 Design is a leading-edge provider of services to the radio communications and telephony markets, offering sales, support, exclusive software products, and ROIP training and design expertise.

Their cutting edge state-wide communications system for Washington State Department of Fish and Wildlife provides an economical, reliable ROIP dispatch solution covering regional offices and more than 150 field officers patrolling some of the most rugged, isolated geography in the United States.

Phase 4's principal enginer, Dave Grant, designed the network using DCB's UT encrypted tunnels in a network that links 22 Telex control stations with remote repeaters in a way that allows multiple frequency scanning and multiple repeater sites in a challenging environment.

Using DCB encrypted tunnels that securely transport all ethernet traffic types, he can later add a SIP-based VOIP telephone system on the same data path allowing tactical phone integration throughout their network, external connections, and even remote satellite connections. Read about the project at their web site here.

UT encrypted tunnels enable many wide-area ROIP and VOIP installations around the world. For UT encrypted tunnel information, click here.
