Additional telephones on the modem phone line
The StormPort 405 is used to connect a computer and telephone to the same
line, providing simultaneous voice/high-speed data service. Telephones or
answering devices connected directly to the StormPort 405 do not require
external telephone filters. The StormPort 405 has a built-in voiceband filter on
the telephone connection to insure that the signal noise of the data traffic does
not interfere with voice conversations.
However, if there are additional phones (on different jacks) connected to the
same line as the StormPort 405 (extension phones, etc.), an external filter may
be needed.
It is recommended that all filters be installed. Test all additional lines for
correct operation (no data noise) while the StormPort 405 is running and in
service. .
You can order voiceband filters from the StormPort 405product distributor or
service provider.
