Chapter 8 • Configuring the HN router for VADB backup
58
1037753-0001 Revision A
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.
• 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
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.
Note: The HN router can be upgraded to support VADB
operation after it is installed.
