The UT PC client software works in conjuction with a UT or XT fmaily of encryption servers. It allows a PC to participate in the encrypted network without additional hardware at the client location.

The UT PC Client software creates a layer 2 tunnel, which sets it apart from other VPN software. In practical application terms, this feature allows all protocols to pass between the PC and the network on the server side. The protocols include multi-cast, which is often used for VOIP and video applications.

The UT and XT server hardware is available in models that host from 8 to hundreds of clients

The UT/XT series uses AES encryption which is replacing DES/3DES encryption. The encryption can be 128, 192 or 256 bit, or encryption can be turned off.

The UT/XT series operates through firewalls requiring only one UDP/IP port, which can be any port. All Ethernet protocols are bridged, including multi-cast, IPX, IP, NetBEUI, etc. The UT/XT series is straight-forward, easy to configure and maintain.

The UT/XT series has state-of-the-art AES encryption security without the configuration complexity of VPN.

The server typically has a fixed IP address. Clients can have fixed IP addresses or use DHCP to obtain their address. Dynamic DNS is supported in UT ans XT hardware servers.

If you need to attach an entire subnet at a location to the encrypted network, see our complete hardware product line.

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

Due to the encryption employed in these products, UT/XT 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 UT and XT series products may be 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 may be shipped to most other countries.



Protocol Features



The UT-SOFT software is suppliled on a CDROM. Each user client instance is configured using a unique software key supplied with the CDROM. The software is installed on a PC using a Windows installer program. When installing the software, the user/administrator enters the software key as part of the installation process. A PC may have more than one instance of the PC Client software operating at the same time. There must be one license purchased for each instance of the software running on a PC.


How it works

The UT-SOFT client software is installed on a Windows PC. Installation is similar to the installation of a network driver. It allows the Windows PC to participate in a UT/XT encrypted tunnel network without requiring UT/XT hardware at the PC site. The UT/XT family products create an encrypted tunnel which passes Ethernet packets between two trusted LAN segments. All ethernet protocols are bridged between the UT/XT units. The UT/XT only operates in conjunction with other UT/XT units. One unit is required for each location. Multiple client units may be connected to the same host unit, and a client may be connected to multiple host units (daisy-chained operation). A host unit may be configured to block client-unit to client-unit connections, or to allow them. All UT/XT series units are compatible.

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.

UT Product Security In Perspective
This document provides an overview of the UT security perspective as well as best practices for configuring UT encryptors.

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.

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.

The UT series operates similarly to our ET series encrypted tunnel. The main difference between the two product lines is that the UT uses UDP/IP protocol for the tunnel link while the ET uses TCP/IP for the tunnel link protocol. The following ET application notes apply to the UT as well as the ET series.
