1.4 WWAN technology used in the device

As previously mentioned, the device uses two types of WWAN technology depending on the WWAN modem connec-

ted to the USB port:

• HSDPA technology (High-Speed Downlink Packet Access).

• HSUPA technology (High Speed Uplink Packet Access).

The following USB modems are currently supported with Teldat-3Ge-USB software version 1.10:

• Sierra Wireless Compass 885

• Sierra Wireless Apex 880U

• Novatel MC990D

• Huawei K3520

Note

The Teldat-3Ge-USB does not support the voice backup feature included on the Teldat-3Ge device.

The Teldat-3Ge-USB boots up without an IP address in its Ethernet interface. It requests an IP address using DHCP

and only accepts the address offered by the corporate router, rejecting other addresses from DHCP servers connec-

ted to the local corporate network. This is achieved by configuring the corporate router as a DHCP server, which then

only offers IP addresses to requests from a Teldat-3Ge-USB. DHCP is also used to convey configuration information

to the Teldat-3Ge-USB.
