Modem configuration
Although most connections will work appropriately with the default settings on
SV1115IPEXT, manual changes can be made. To do so:
Login to the Web interface as Admin. Click Modem, listed on the left side of the main
page. 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 SV1115IPEXT’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 initialization (“init”) string is the command (using the standardized Hayes AT
command set) that the SV1115IPEXT 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.
