|8/24/2020||Ripple20 Malware Information||The latest malware going around is known as Ripple20. |
The JSOF research lab discovered a series of zero-day vulnerabilities in a widely used low-level TCP/IP software library developed by Treck, Inc. The 19 vulnerabilities, given the name Ripple20, affect hundreds of millions of devices (or more) and include multiple remote code execution vulnerabilities. The risks inherent in this situation are high.
No products produced by DCB use the Treck or Elmic TCP/IP stack, or a TCP/IP stack derived from the Treck library. They are not subject to this vulnerability. The DCB Encrypted Tunnel product line uses the Linux TCP/IP stack for networking functionality. It is not impacted by the Ripple20 vulnerability.

|12/16/2019||XT-3305 Replaces the UT-3302 and ET-3302||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.
|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.|

|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.
|The HSW-08 ethernet switch is on sale for $150 each regardless of quantity! This is an 8 port wide temperature range 100BaseT switch with multiple power options in a rugged metal box. Check out the specs here for your critical network installation.|

|7/02/2017||DCB Products Enable ROIP Network
|Our long-time partner, Phase 4 Design (http://www.phase4.org), 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.
