XT-3305 Replaces the UT-3302 and ET-3302 img

img The UT-3302 and ET-3302 encrypted tunnels were released in 2009 and replaced with the XT-3305 in 2019. While we maintain inventory to expand existing installations, we've depleted our inventory for new installations.

We recommend the higher performing XT-3305 as a replacement for new installations. The newer XT Family of encrypters offers increased throughput and is 100% compatible with all UT and ET products. Click here to read the details.

Enhanced Priority
Audio Switch

img Recently, we've seen increased interest in our Priority Audio Switch. The Priority Audio Switch is used to permit multiple control points or microphones to access a single transmitter. This is common in airport control towers, remote transmitters, and forward operating bases with both a local control point and a remote one. DCB's PAS allows the PTT and audio from two sources to automically control one output device. There are two instances of this hardware in each unit, allowing cascade for three inputs or controlling two different transmitters. Click here to read the details.

One-on-One training with Loop International img

img We periodically send members of the Loop Telecom's North American TAC support team (DCB personnel) to Taiwan for personal training on updated and new Loop International Products. In addition to enhancing personal relationships with Loop factory engineers and FAEs, this keeps us current on the latest product changes, new products, and future directions. For the Spring 2019 trip, the emphasis is on new packet transport products and TDM to packet transition... making it an evolution instead of a forklift change. In addition to building deeper friendships between the factory and the North American TAC suppot team, current product updates include the AM3440 series, IP6760, IP-6702, PTN 1G and 10G cards, G7860A, iNET PTN and iNMS.

Enhanced Packet Repeater Released img

img Continuing the DCB tradition of improving products without raising the price, enhanced firmware for the Packet Repeater PR-6606 was released this week. This new firmware allows up to 400 destination addresses selected by up to 20 selection rules with 20 destinations each. When moving to the 6606 hardware platform, we were conservative with the specifications until we had sufficient real-world experience with its actual capabilities. All new orders ship with the new firmware, and existing PR-6606 customers can upgrade by downloading a copy from our web site support section. Click here to read the details.

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.
