Software overview
The Patton Model 3125 supports all common remote access services as well as integrated routing and forward-
ing (see table 3). Authentication and network management offer control and detailed monitoring from any
web browser. From the PSTN, the Model 3125 RAS will accept either T1/E1 or PRI connections, with sup-
port for both channel associated or common channel signaling.
