 Note the Active Connection value.
If the Main Connection is good, the Active Connection value will be Main.
If the Main Connection is down, the Out-of-Band/Failover section displays information relating to a configured Out-of-Band/Failover
interface and the status of that connection. The IP Address of the Out-of-Band/Failover interface will be presented in the Out-of-
Band/Failover section once the Out-of-Band/Failover connection has been triggered and made.
6.7.3 CELLULAR ROUTING
Once you have a configured carrier connection, the cellular modem can be configured to route traffic through the console server.
This requires setting up forwarding and masquerading as detailed in Section 6.8.
6.7.4 CELLULAR CSD DIAL-IN
CSD is a legacy form ofdatatransmission developed for TDMA-based mobile phonesystems likeGSM. CSD uses a single
radiotime slotto deliver 9.6 kbps data transmission to the GSMNetwork and Switching Subsystemwhere it could be connected
through the equivalent of a normal modemto thePublic Switched Telephone Network(PSTN) allowing direct calls to anydial-
upservice.
CSD is provided selectively by carriers and it is important you receive a Data Terminating number as part of the mobile service your
carrier provides. This is the number that external modems will call to access the console server.
Once you have configured carrier connection, the cellular modem can be configured to receive Circuit Switched Data(CSD) calls.
