RuggedCom RX1000 Network Router User Manual


 
Chapter 11 - Configuring PPP and Modem
The Dial-in console field allows the modem to answer incoming calls and present a
login screen in the same way that the console serial port does. The login used for the
Dial-in console is the same as that used for SSH and serial console logins.
Note If RADIUS authentication is enabled, the Dial-In Console login will
be in the LOGIN group and not in the PPP group. See the section:RADIUS
Authentication for details.
The PPP server field configures the router to answer incoming modem calls and
negotiate a PPP connection to the calling system to provide network access.
The RADIUS Authentication field will cause incoming PPP connections to be
authenticated against the RADIUS servers configured in the Maintenance menu,
RADIUS Authentication sub-menu.
Note The Dial-in Console and PPP Server can be enabled at the same
time. The router will automatically detect whether an incoming call is PPP or
console only. If PPP Client mode is active, it will try to maintain the PPP link
at all times, and hence block incoming calls most of the time. Enabling the
PPP Client at the same time as the Dial-in Console and/or PPP Server is not
recommended.
Rings before answer controls how many times to let the modem ring before
answering a call, if either of Dial-in console or PPP Server is enabled.
Additional Modem AT Init Codes allows extra AT command codes to be entered if
required. Note that care must be taken to ensure the correctness of any AT command
codes entered here, as the router does not verify them. A selection of supported AT
codes for the Internal modem follow. For equivalent codes for an external modem,
please refer to the documentation for the external modem used.
