In some cases, when testing the operation of an extension port when
connecting to a IP1WW-2PGDAD, a technician may connect a line cord
directly from an extension port on the CD-8DLCA/CD-16DLCA Blade.
Though this is not the recommended connection, it can be used to test
these devices.
Should a direct connection of this type be made to the base station of the
IP1WW-2PGDAD, the line cord must be 2-wire (1-pair). If a 2-pair wire is
used, the system provides power to the unused pair. This can prevent
the cordless telephone from acquiring a link with the base station or it
can damage the IP1WW-2PGDAD or the SV8100 station card.
To wall mount the IP1WW-2PGDAD, insert two wood screws 100mm apart (3
15/16"). Leave 3mm (1/8") of the screw exposed. The screws can be installed
either vertical or horizontal, depending on which position fits best for your
location.
