| TLS v1.0 & v1.1 Changes
|
| Microsoft recently pushed out a patch that removes all support for TLS v1.0 and v1.1. This means that customers running old firmware on their ET or UT device may be unable to start a configuration web session with the device. The error messages report that there is no common security protocol or encryption algorithms.

| EST-9600 Replaces Modem Links In Motorola Radio Systems
|
| As analog leased lines disappear, customers using Motorola repeater systems such as the Quantar, DIU 3000, MLC 8000, and GTR800 systems are using the EST-9600 to replace V.24 modem links with synchronous connections over IP links. These work well with internal ethernet networks, the Internet, and even ISM wireless links.

| New EST-9600 Quick Setup Guide
|
| When their analog lines are disconnected, many customers are using the EST-9600 to replace V.24 modem links with synchronous connections over IP links. These work well on most any IP link and are used for remote radio connections, radar data and other streaming content as well as polled SCADA systems.

PR-6606, PR-6602 Advanced Features 
|
|
The PR-6602 standard performance packet repeater handles up to to 5,000 Packets/Second and 50 destinations. It's often used in Industrial, SCADA, ROIP, streaming audio broadcast and unicast to multicast translation installations. Works for smaller Netflow installations and commonly used for duplicating data streams to multiple locations.
We also produce the PR-6606 high performance unit with up to 120,000 Packets/Second and 400 destinations. It is normally used for larger Netflow, Sflow, SNMP, video streaming, and complex networks. Both units allow for bidirectional UDP packet replication, source IP address spoofing (or maintaining original source addresses), simulating multicast using unicast and allowing multicast applications on a unicast system, and more!

Modems Are Still Important
|
|
Many people think telephone line modems are relics of the past. This couldn't be farther from the truth. Modern modems are used in applications for remote data gathering from wind and solar farms, railroad communications, military communications (via wireline, satellite, and radio), and last-option Internet connections. They are commonly used in ATM machines, vending machines, utility networks, two-way radio networks, and out-of-band management. DCB has been building high quality modems for over 20 years using modern digital signal processing chips as well as traditional components. More information on our modern modem products is here. |

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. For more information on Ripple20, check out https://www.jsof-tech.com/ripple20/ |
