Requirements for VADB The following requirements must be fulfilled before VADB can be used:
•The HN router must be configured for VADB operation before the system is installed and commissioned.
Note: The HN router can be upgraded to support VADB operation after it is installed.
Installing VADB
•The site must have an analog telephone line to support VADB operation. A dedicated telephone line is preferred but not required. The HN router can share the telephone line with other devices when it is connected to a splitter.
The following tasks must be completed for VADB to work properly:
•Before testing VADB functionality, you must use a phone handset to dial the VADB access phone number. For details, refer to Testing the telephone line on page 60.
•The telephone cable must be plugged into the TEL LINE port on the HN router and a telephone jack or splitter. (In some countries, a converter may be required to connect the cable to the phone jack.)
Installing VADB consists of the following tasks:
•Verifying that the VADB profile is loaded
•Testing the telephone line
•Testing VADB functionality
Before beginning the installation, check the telephone line local dialing rules. If it does not match the sequence in the installation specification, or as shown in the Advanced Pages, (see VADB troubleshooting on page 66), contact Installer Support.
