The DUAL-1 is a High Performance Rate-Adapting, Switched or Dedicated CSU/DSU, all in one package. Connecting to the digital network is now easier than ever. The Dual-1 performs Bell compatible encoding and decoding, system timing, proper interface and complete diagnostics in a small reliable package. The Dual-1 provides speed adaption in either synch or asynch mode, thus allowing connected terminals to run at speeds less than 56K. Speeds of 300 bps through 57.6K are possible in this mode. The Dual-1 can operate 56K or 57.6K asynch.

A Step Above Microprocessors, the DUAL-1 Uses Programmable Logic. The Dual-1 provides the interface buffering to convert your terminal speed to 56K line signaling. This means that you can install your high speed digital lines today at 56K without having to upgrade your terminal equipment. Also, using the programmable logic, the user can select between dedicated and switched circuit applications with the Dual-1. The Dual-1 programmable logic allows quick user change overs that are completely transparent to your system.

Adaptive Distance Compensation Circuitry automatically analyses your link and compensates for distortions. This assures optimum performance all the time.

Three Interface Connectors Give Great Interface Flexibility. The DUAL-1 provides both V.35 and DB-25 connectors as well as the necessary interface circuitry for your DTE. Any speed can be run through either interface. A second DB-25 connector is available for your dialing programming. Users can select from industry standard dialing commands or RS-366. Operating configurations can be remotely selected either on a dial or dedicated line.

SPEAK-EZ-2

The SPEAK EZ-2 Provides the User Several Voice Interface Options Built In. Answer a question about the application. That is it! No Complex menu is used and you don't need to learn a foreign language. Its EZ to set for your particular application and once set there is no fear that parameters might get "lost" due to power glitches. You just set the switch for the application and connect to the correct jack. Your voice channel is ready to use. That Voice Channel can be used for FAX communications as well. Data and Telephone circuitry are powered from their own isolated supplies, eliminating ground loops between your telephone system and the data terminals.

We Did Not Forget Your Data Needs Either. The data channel provides both synchronous and asynchronous operation. Speeds from 38.4K down to 9.6K are provided for great flexibility. we know that data interfaces can change, so we provide both V.35 and RS-232 interfaces and connectors.

Highly Integrated State of the Art LSI Technology Is Used. These devices are custom programmed by BAT. We are in control of these parts, not some custom LSI parts house. BAT Electronics has spent years developing the circuitry algorithyms which allow us to produce our low cost products. Our designs result in lower parts counts, which yield improved reliability, reduced size and lowered power requirements. These factors lower the cost.

Think of the SPEAK EZ-2 as a Rate Adapting CSU/DSU With a Low Cost Voice Channel. In many cases your terminal equipment can not use the full 56K speed, yet today these circuits can actually cost less than analog circuits. For slightly more money than our competitors Rate Adapting CSU/DSU you get the Voice Channel. And this channel can be used for fax.

This application the two locations are linked by a 56K circuit using the SPEAK EZ-2. The muxes may have been removed from and old analog circuit but they can not use the full 56K speed of the digital circuit. The SPEAK EZ-2 will rate adapt to the mux speed and offer a voice circuit between the two facilities for slightly more money than just a plain rate adapting CSU/DSU. The interface to connect to the PBX is included in the SPEAK EZ-2.

This system illustrate how two remote LANs can be connected via a 56K link using the SPEAK EZ-2. The user now has the benefit of a voice channel that can link the two facilities. Such an application may be found linking a remote sales office using PCs for order entry connected on a LAN communicating with a home office. The necessary telephone interface circuitry is included in the SPEAK EZ-2. No special connection options need be purchased. The SPEAK EZ-2 has both V.35 and RS-232 interfaces and connectors, to support a greater variety of bridges.

This application shows how a PC used in a point of sale system can be linked by the SPEAK EZ-2 from the retail center to the home office. The SPEAK EZ-2 can handle asynchronous data, so there is additional hardware cost savings. The SPEAK EZ-2 provides the asynchronous to synchronous conversion and rate adaption automatically. The user can run the PC at either 19.2K or 38.4K as well. Again all of the necessary telephone interfaces are provided. In fact the central and remote SPEAK EZ-2 units are the same. Only their programming dip switches set differently.

This system illustrates how a remote office using a CRT cluster controller can be linked to headquarters using the SPEAK EZ-2. The controllers can not use the full 56K bandwidth. The SPEAK EZ-2 provides the rate of adaption. The extra bandwidth is used to provide a voice channel between the two locations. The incremental cost over our competitors' rate savings pay for the cost of the SPEAK EZ-2. All of the telephone interfaces are included and are easily set by a rear panel dip switch. The SPEAK EZ-2 includes network level diagnostics to help you install and maintain the link.

VRT-4

The VRT-4 is a high performance CSU/DSU that splits the 56K DDS stream into 2, 3, or 4 channels. Each of the channels is completely independent and transparent. The VRT-4 provides all the clock buffering and data sychronization. As an added benefit, for asychronous operation each channel has an asychronous and synchronous converter. In addition the VRT-4 performs Bell compatible encoding and decoding, system timing, proper interfacing, and comes with a complete diagnostics in a small, reliable package.

Configuration flexibility is provided by the VRT-4. The VRT-4 operates in four user selectable modes that provide a large range of terminal speeds and interface configurations. The chart on the specifications illustrates its high degree of flexibility. Channels can operate independently either sychronous or asynchronous. Four RS-232 connectors are provided as well as all of the necessary interfaces. You will not need clumsy adapter cables or extra interface converters. We even provide a V.35 interface on channel one.

Advanced adaptive Distance Compensation Circuitry analyzes your and compensates for distances. This assures that the VRT-4 is tuned to the optimum performance for your particular installation, extracting the best possible results from your digital circuit, even under marginal conditions. The distance capabilities of the VRT-4 far exceed the telephone company requirements.

State of the Art LSI Technology is used in the VRT-4. LSI technology means fewer parts and much lower power consumption. To the user this means much higher reliability and a great deal more of functionality.

Smart Diagnostics that work for you and with you to provide the tools needed to manage your circuits. All the appropriate telco loopbacks are provided. Full remote capabilities re also provided. The BAT VRT-4 can be used to assist you to troubleshoot every part of your link. A smart In Service LED guides the installer through the installation process. Switchable LED's monitor channel activity.
