External Dial Backup Support

Netopia equipment that supports the external dial backup feature automatically display the serial port configuration menus described in the following sections.

Models that do not support external dial backup do not display external dial backup-related menus, but offer menus for backup to a default gateway. Generally, models that support external dial backup can be determined from the following matrix:

External Dial Backup – Supported Models Matrix

WAN Interface:	T1	SDSL	SHDSL	ADSL
IADs:	Yes	Yes	Yes	*
Data Routers:	Yes	Yes	Yes	*

*ADSL models do not currently support dial backup, but will support it in a revision in the near future.
