Analog Over IP Line Extender
SmartNode SN2290 Analog-over-IP Leased Line Extender | 2 or 4 lines

End of Life Notice (PDF). This legacy product is not recommended for new installations. For next-generation alternatives, please contact for the recommended replacement.

The SmartNode™ 2290 Series Leased Line Extender enables end users to deploy such leased-line applications an "always-on" connections over the Internet or other IP networks. Install one Telephone/Analog-over-Ethernet Extender on each side to transport up to four audio leased-lines over a packet-based network. This means you can establish up to four leased-line circuits between two Internet access locations anywhere in the world!

Many service providers are discontinuing their TDM backbone networks and analog leased-line offerings. The 2290 series offers service providers a chance to offer the same always-on services as analog leased lines over their new, coverged-IP networks.

For enterprises, the SN2290 Telephone/Analog-over-Ethernet Extender offers a chance to migrate to best effort networks like the Internet and enjoy the same benefits of using analog leased lines with the existing local area network they have already deployed. In addition, it allows them to use LANs to provide intraoOffice always-on lines instead of a dedicated web of telephone wires.

After installation, the connection between two SN2290 Telephone/Analog-over-Ethernet Extenders establishes immediately, and re-establishes itself after any network disruption. The connection can also be secured with hardware-accelerated 3DES or AES encryption end-to-end. Such security technology prevents wiretapping, making Patton the ideal choice for security-conscious enterprises.
