Have a need for a Data Service Unit that is designed to set on a desktop ?
This item is New and has Never been Used.
There is NO AC/Adapter Power Supply for this Unit
It has been setting on the shelf for a while so the box is a little dingy. However, I can say with a Very High degree of certainty that it will in no way affect the operation of the unit.
Package includes:
1 - Desktop DSU
1 - Users Manual
1 - DDS Network Cable
The DeskTop 56/64 is a low cost, high performance and high quality data service unit (DSU) aesthetically designed for office environments. It supports 56 Kbps and 64 Kbps clear channel high speed data rates in standard digital point-to-point or multipoint networks. It is also a cost-effective data service unit for point-to-point limited distance applications. Designed for easy, plug-and-go installation, the DT 56/64 unit simplifies initial installation and future service upgrades. This highly reliable, user-friendly product combines superior performance with a sleek, compact design that blends well with any surroundings. The DT 56/64 unit is line compatible and diagnostic-test compatible with GDC's other DSU products, including the SpectraComm 500A designed for central sites. It is also line compatible with non-GDC DSUs operating at 56/64 Kbps that are compliant with the Bell Publication 62310.
The DT 56/64 is configured using simple, clearly marked switches on the bottom of the unit. An optioning information chart is also provided on the bottom of the unit. There is no need to wrestle with complicated prompts, confusing menu trees or lengthy instruction manuals. To make things even simpler, the unit can be preconfigured at a central site and then delivered to remote sites for plug-in installation.
