Using LSI Technology, the VRT-1 provides 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 up grade your terminal equipment. The VRT-1 provides appropriate interface and conversions. The process is completely transparent to your system. As an added benefit, you can also operate asynchronous devices. The necessary conversion circuitry is provided by the VRT-1. LSI Technology greatly reduces the size of the enclosure and power consumption. Fewer parts and lower power means greater reliability.

Adaptive Distance Compensation Circuitry analyses your link and compensates for distortions. This assures that the VRT-1 is tuned to the optimum performance for your particular installation, extracting the best possible results from your digital circuit. With this advanced circuitry you get better performance under marginal conditions. This means you can take full advantage of the through put capabilities of your digital circuit. Line loss capabilities of the VRT-1 far surpass telephone company requirements.

Interface Flexibility is assured. The VRT-1 provides speeds from 56K down to 1.2K. Both V.35 and RS-232 connectors are provided as well as the interface circuitry.

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 are also provided. The BAT VRT-1 can be used to assist you to trouble shoot every part of your link.

The VRT-1 is covered by BAT Electronics' EZ Lifetime Warranty
