VADB troubleshooting on page 66

The VADB feature provides a phone-line backup capability to the HN router in case the DSL line fails or degrades below an acceptable threshold.

The HN router contains an internal modem to support VADB functionality. The HN router connects to a national network of dial access numbers, which are known as a Point of Presence (POP). Each POP acts as a Virtual Private Network (VPN) entry point into the customer’s network or the Internet. The HN router sends packets through the POP to the Network Operations Center (NOC), which forwards the packets to the destination server.

VADB automatically switches the HN router to a terrestrial dialup telephone network with minimal interruption and loss of customer traffic. VADB introduces no additional load on the HN router and does not affect any existing HN router features, but it does cause the HN router to send and receive traffic at a slower rate.
