DESCRIPTION

The ET-6600 is an industrial temperature rated device (Internet Appliance) for creating encrypted Ethernet tunnels. To meet your needs, the basic unit is available in three models...The ET-6600 features two serial ports and two Ethernet LAN ports. The ET-6690 has two ethernet ports, one RS-232 port, and one internal modem port. The ET-3302 has one untrusted ethernet port and a four-port switch on the trusted side.

The ET series encryption appliances encrypt data between private networks using the public Internet or any other network as the transport.

The ET series uses AES 128-bit or 256-bit encryption. AES is the US Government standard, selected using an open selection process, to replace DES and 3DES encryption. AES is required by many US government regulations.

ET-6600 units can be connected Ethernet to Ethernet or serial to serial. The serial connection can also be used as an automatic fall-back connection should the Ethernet fail.

The ET series operates through firewalls with only one port of your choice opened. It bridges all Ethernet protocols including IPX, IP, Netbuei, and other non-routable proprietary protocols. It is often used to transport multi-cast IP

All ET and XT family products interoperate. All may be configured as a partner with any other unit. For example, the lower cost ET-6600 models are often used as partners with the high performance ET or XT products. The higher performance units are often used with hundreds of client locations, high performance VOIP, and complex networks.

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.

For encryption of serial RS-232 links not involving ethernet or IP, see our SE-6600 product line.

Due to the encryption employed in these products, ET series products are export controlled items and are regulated by the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce. The ET-6600 and ET-6690 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 shippable to most other countries.

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.

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.
