Common Applications

The ET-6604 and ET-6620 are often used as the host in conjunction with multiple smaller ET remote products. In higher performance applications, ET-6604 or ET-6620 units are used in pairs for high bandwidth point-to-point encrypted links.
  • Utilities – Gas and oil production, pipelines, electric generation, transmission and distribution
  • Retail – Stores, kiosks, credit card machines --- especially those using wireless links
  • Law Enforcement – Small remote offices
  • Medical – AES encryption of the ET-6600 meets HIPAA requirement for securing data over open networks such as the Internet. The medical industry is mandated by HIPAA to meet HIPAA privacy and security requirements over open networks.
  • Real Estate – Connecting to and updating the database of listed homes.
  • Field sales – personnel working out of the home, hotel rooms wired for high speed Internet access.
  • Financial industry – Additional security on internal corporate links, branch offices, ATM machines, key personnel remote secure access.
  • Remote office with more than one device, with the ET-6600 shared with switch or hub.
  • Added security within a large corporate network
  • Office to Home
  • 2 nets at each end, bridged via the Internet
  • Remote network monitoring via the Internet

DESCRIPTION

The ET-6604 is an Internet Appliance device for creating encrypted ethernet tunnels. It features two Gigabit ethernet LAN ports (10/100/1000 BaseT) . The ET-6604 can encrypt data at a rate up to 40 megabits per second.

The ET-6604 encrypts data between private networks using the public Internet or any private Intranet network as the transport.

The ET series uses AES 128 bit encryption. AES is the US Government standard, selected using an open selection process, to replace DES and 3DES encryption.

The ET series operates through firewalls with only one port of your choice opened. It bridges all ethernet protocols including IPX, IP, NetBEUI and other proprietary protocols.

The ET series is straight-forward, easy to configure and maintain. The ET series has state-of-the-art AES encryption security without the configuration complexity of VPN.

The ET-6620 and ET-6604 operate with an internal encrypted pass-phrase database or an external Radius server. The external Radius server could be the same one used for other devices in an organization's IT department.

Due to the encryption employed in these products, the ET-6604 and ET-6620 series products are export controlled items and are regulated by the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce. Export regulations may delay delivery to some areas. The ET products will not be exported or shipped for re-export to Country Group E:1 as defined by the BIS. The ET-6604 is readily exported to most other countries using the "ENC" exemption. The ET-6620 requires an individual export license for each delivery outside the USA. Our companion products, the ET-6600 and ET-3300 are exportable under similar regulations as "mass market encryption devices".

Quick-start guide to the XT family products.
This application note guides the new XT user from opening the boxes to having a working encrypted tunnel between two XT units on a test bench. Step-by-step instructions make it quick and painless to learn the configuration process. Uses the XT-hEX as an example, but also covers other XT products.

Troubleshooting guide for the above Quick-start.
If it didn't go well and doesn't immediately work, this guide offers some troubleshooting hints. Most people won't need this, but it's here if you do.


What Do Those Tunnel Log Entries Mean?
When analyzing logs from DCB Tunnels (XT, UT, ET, and FT), there are often log entries that are surprising to the new user. We discuss those here.


Configuring the LAN3 on the XT-hEX, a Quick-start guide.
Most people won't need this, but if you want to use the third LAN port on the XT-hEX, this information will help you configure it.


All DCB ethenet encryptors operate similarly, with differences being in the protocols, capabilities, and authentication methods. Since the topology is comparable for all of them, we show application notes for all these products together.

DCB's Encryption Product Export Statement
Some of our encryption products are export controlled items and are regulated by the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce. Some are classified as mass market encryption devices and may not be exported or shipped for re-export to restricted countries in Country Group E:1. They are exportable to most other countries. Read our Encryption Product Export Statement here for more specifics.

Using XT Tunnels with IP Radio Dispatch Systems.
Radio installers rely on DCB tunnel products to implement secure networks for mission critical applications. DCB Encryptors (XT, UT, and ET roducts) enable IP dispatching across multiple networks. They remove the multi-cast problem faced in many IP network installations so are frequently used along with Telex, Motorola, Kenwood, Harris, Zetron, AVTEC, and other two-way radio consoles. This document describes some of those techniques with examples we've seen at PSAPs and other dispatch centers.

Tunnel Product Security In Perspective.
Our encrypted tunnel appliances provides a LAN -to- LAN encrypted tunnel between locations. It employs a layer three (UDP/IP or TCP/IP) connection between two or more tunnel devices to create a secure, AES encrypted tunnel. For export purposes, the Some models are considered a Mass Market Encryption Device by the Department of State Bureau of Industrial Security and are export limited.

This product line meets HIPPA and most government standards for non-classified data transfer. However, it is not NIST FIPS 140-2 approved. For a FIPS 140 approved product, the (more expensive) FT line of encryption appliances is required. This note discusses the security implications of using our encrypted tunnels.


Redundancy Techniques Using DCB Tunnel Devices and Software.
Users have come to rely on DCB tunnel products to implement secure networks for mission critical applications in which downtime must be kept to a minimum. Thus it is not unusual for customers to ask questions about techniques that may be applied to make the tunnel network more robust. This document describes some of those techniques with examples.
Quick-start guide to the XT-3306.
This application note guides the new XT-3306 user from opening the boxes to having a working encrypted tunnel between two XT-3306 units on a test bench. Step-by-step instructions make it quick and painless to learn the configuration process. One difference between the XT and the UT/ET families is that the XT allows the selection of TCP and UDP protocols for the tunnel path.

Troubleshooting guide for the above Quick-start.
If it didn't go well and doesn't immediately work, this guide offers some troubleshooting hints. Most people won't need this, but it's here if you do.

Quick-start guide to the UT-3302.
This application note guides the new UT-3302 user from opening the boxes to having a working encrypted tunnel between two UT-3302 units on a test bench. Step-by-step instructions make it quick and painless to learn the configuration process.

Discusses applying the UT products to transport VOIP multicast via non-multicast wide area networks. Examples showing IP voice dispatch radios for public service agencies. The UT supports multi-cast IP over normal uni-cast networks and allows a private multi-cast network to span multiple IP networks. The UT-SOFT software client allows any PC to be a securely connected node on a remote network

Motorola MIP 5000 VoIP Radio Console VPN Solution Guide
This Motorola produced MIP 5000 VoIP Radio Console VPN Solution Guide features a virtual private network (VPN) solution that has been tested with MIP 5000 VoIP Radio Console. The VPN solution uses a pair of encrypted Ethernet bridges to provide a secure Ethernet tunnel between the dispatch center and a remote MIP 5000 console. The secure Ethernet tunnel supports a remote console operator receiving audio from and transmitting audio to radio channels and other MIP 5000 consoles using AES encryption.

UT Tunnel Installation Note - "Living On a Wild Feed... Safely"
This short application note summarizes the options and requirements for directly connecting the untrusted interface of UT encrypted tunnels to the Internet. Yes, the UT tunnels may be safely living on the wild side of your firewalls and if properly configured appear to be a "black hole" to your adversaries!

Using the UT for Remote Management Applications Since the UT along with UT-Soft enables a remote workstation to have a virtual presence on a remote LAN segment, it's quite useful for network monitoring and analysis, similar to a RMON without the headaches. Download an application note that discusses using UT-Soft and our UT servers for remote LAN network montoring.
