Login to the Web interface as Admin. Click Admin/Setup from the top of the page and choose
Modem (PPP) setup.
You will then be presented with the Modem Option menu (see above). Make the following
changes to enable and configure the modem connection.
• Enable modem connections (PPP) via serial port/modem: select Enabled.
• Baud rate to use (affects connection between us and the modem only): select 115200.
• Init string: leave as ATE0S0=1&K3 (see below).
The baud rate dictates the connection speed between the SVx41HDI’s serial port and the modem,
and does not affect the connection speed between the local and remote modems, as they will
negotiate their own connection speed when a connection is made. It is highly recommended that
this setting be left at the default for best performance.
The init string is the command (using the standardized Hayes AT command set) that the
SVx41HDI will send to the modem to activate it. The string included should work with the
majority of modems and configures the following connection properties: answer incoming calls
on the first ring, enable hardware flow control, and lock the connection speed. Your modem’s
documentation will describe other potential init strings that you can use to alter the connection
properties. For instance, you could commit the settings to the modem’s non-volatile memory
(NVRAM) or allow the modem to adjust the connection speed for greater stability (and so on).
You may wish to test the connection with the default init string first before making changes
specific to your modem model or situation to simplify the troubleshooting process.
Click the Commit button to save your changes and activate the modem feature with the specified
settings.
