Internet Access with Fast Symmetric Connection

High speed symmetric data transmission

The P-791R v2 is a high performance SHDSL.bis router for small/medium office to have Internet access and LAN-to-LAN application over the existing copper line. The P-791R v2 makes full use of the advanced G.SHDSL.bis technology, its symmetric transmission data rate can be up to 5.69Mbps.

UPnP support

The P-791 v2 supports UPnP discovery and UPnP NAT traversal. By using the standard TCP/IP protocol, the P-791 v2 can dynamically join a network and obtain an IP address as well as convey its capabilities and learn about other devices on a network.

Auto Fail-over and Fall-back WAN backup solution

The P-791R v2 features a fail-over and fail-back WAN backup solution for complete reliability. When the DSL connection fails, traffic is forwarded to either a backup ISDN or analog modem to maintain data exchange. When the DSL connection is re-established, traffic will be fully restored. The P-791R v2 also performs backup functions by redirecting traffic to a specific gateway to ensure availability of the Internet connection. The WAN backup solution saves device maintenance cost and reduces loss from daily operation.
