Patton RAS
Remote Access Servers

Back in the day when dial-up was the main way people accessed the internet, Patton Electronics supplied lots of small to medium size Internet Service Providers with their "pizza-box" Remote Access Servers. 
Patton sold lots of the 2960 RAS and 2996 RAS boxes  

Patton Electronics also offered the same dial-in technology in a RAS Card
which was plugged into a server
They sold lots of Patton 2977 RAS Cards

Dial up is no longer what it once was, the Patton RAS products still fill a niche. They are probably the least expensive way to provide Remote Dial access with T1's still available, especially when you can find refurbished equipment.  They are still used for all kinds of dial applications including FAX and Patton still provides technical support.

We have available both new and refurbished Patton RAS boxes and Patton RAS cards backed with our warranty.  Here links to the products and their specifications.   If you click-through, you will see that we have included both DIGI and PATTON part numbers where applicable -- and data sheets.
