2.1.1 Data Backup

The Teldat router manages the Teldat-3Ge through three virtual rcellular interfaces. This approach lets the router
provide the same configuration and monitoring features for the Teldat-3Ge as those offered over physical 3G inter-
faces (internal interfaces). Each rcellular interface has a different operational task:
• The first virtual interface (recellular1) monitors the radio link
• The second one (recellular2) is responsible for transmitting traffic the Teldat router sends over the 3G link.
• The third (recellular3) updates the Teldat-3Ge image (firmware).
Communications between the router and the Teldat-3Ge are achieved through a pseudowire L2TP tunnel where
three independent L2TP sessions are established; one for each rcellular interface registered in the router. Con-
sequently, a monitoring session, a data session and a firmware updating session are transported through this L2TP
tunnel.
Fig. 3: L2TP tunnels between the corporate Router and the
RF monitoring consists of a series of parameters on the Teldat-3Ge RF connection level of quality with the GSM and
HSDPA/HSUPA network. This information enables you to appropriately select the location for the device. Monitoring
can be carried out in various ways:
(1) Through the rcellular1 interface sending an AT monitoring command (see manual Dm781-I Cellular Interface).
(2) Opening a Telnet session with the device and executing the monitoring line command.
(3) Accessing the device's web page.
As already indicated, the backup traffic is sent through the rcellular2 interface L2TP tunnel. A PPP session between
the corporate router and the Teldat-3Ge is established over this tunnel with the aim of initiating the connection with
the HSDPA/HSUPA network (authentication and to obtain an IP address from the network).
