Patton Model 3120
96- or 120-port, V.92/V.110/V.90/ISDN, Dial-Up, Remote Access Server (RAS)
This new flexible platform delivers enhanced remote access services
The Model 3120 is V.92 COMPATIBLE!
  Features & Benefits
  • Quad T1/E1/PRI WAN ports
  • Up to 120 simultaneous V.92, V.110, V.90, or ISDN SyncPPP connections
  • Dual 10/100 Ethernet ports
  • Integrated IP Router
  • SNMP/HTTP management
  • Expansion port for sync. serial, async. serial, iDSL connections, 48 modems/ISDN
  • 1U high 19 in. stackable chassis
  • AC and DC power options
  • Dual-redundant hot-swappable load-sharing power supplies

The 3120 supports up to 120 digital ISDN or analog (V.92, V.110, V.90, K56Flex, V.34+, etc.) modem connections in a single 1U-high (1.75 in./4.45 cm) rack-mount chassis. It is the highest density, lowest profile remote access server available anywhere. With its dual-redundant hot-swappable power supplies, the 3120 RAS protects against single-point power failures. It has two 10/100-Mbps Ethernet ports for load sharing and traffic balancing.

For maximum flexibility, the 3120 has a slot for an optional expansion module. ISPs can add asynchronous ports for terminal servers or dedicated DSL modem ports for increasing revenue. The 3120 is a one-of-a-kind Network Access Unit.

Model 3120 High-Density Point-of-Presence Modems Application

Patton?s multi-chassis MLPPP enables service providers to scale additional servers without worrying about rejecting calls. New 3120s added to the ISP?s PoP simply appear as a large virtual modem pool.


Removable dual-redundant power Standard?Supports two AC, two DC, or a mix of AC and DC power supply modules
Dual 10/100 Ethernet Ports?Flexible integration options for your high-performance network
PMC expansion card?Network expansion options enable the 3120 to offer new revenue opportunities

SNMP/HTTP management?Embedded HTTP server provides complete configuration and control using your web browser
Quad T1/E1 ports for 120 RAS or uplink services?Terminate any combination of 120 modems/ISDN connections, or expand into remote locations and use the 3120 as a complete PoP solution
