Chapter 2 Introduction
2.1 Description of the device
The Teldat 4Ge device routes outgoing data from a corporate network to the WWAN network (HSPA+/LTE).
• The Teldat 4Ge always operates with the corporate network output router, routing traffic to the WWAN network in
cases where the main corporate output router drops its main connection.
• The technology used in the WWAN access depends on the wireless modem incorporated in the device. The mo-
dem provides access to the HSPA+/LTE networks for data transmission.
• The device has two possible power sources: external, through an element supplied together with the device, or
through POE (Power over Ethernet). In cases where both are present, the external power source takes priority.

2.2 Application Scenarios
The Teldat 4Ge has two application scenarios:
(1) Routers with WWAN communications that have insufficient network coverage due to location problems. It’s
common practice to install the communication routers in racks, together with other devices, in rooms where the
WWAN coverage isn’t very good.
(2) Backup for routers that don’t have WWAN communications and can divert the outgoing traffic to the Teldat
4Ge.

2.3 Device Interfaces and Connection
The Teldat 4Ge router has two interfaces:
• An interface that provides access to the WWAN network.
• An Ethernet interface.
There are two types of connection between the Teldat 4Ge and the output corporate router:
(1) Connecting the Teldat 4Ge to the corporate network as an additional device on the network, sharing the Ether-
net network with the corporate router.

(2) If the corporate router has more than one Ethernet interface, you can connect a 10 BaseT cable directly from
the router to the Teldat 4Ge, as shown in the following figure.

2.4 Operating features
The Teldat 4Ge starts up without an IP address in its Ethernet (WAN) interface. By means of the DHCP protocol, it
requests an IP address and only accepts the one offered by the corporate router (rejecting other address offers from
other DHCP servers connected to the local corporate network). This is achieved when the corporate router is con-
figured as a DHCP server programmed to only answer the IP address requests that come from a Teldat 4Ge. As
well as offering an IP address, the DHCP protocol is also used to convey the Teldat 4Ge’s configuration.
Fig. 5: DHCP Protocol
The section on how to configure the DHCP protocol explains how to identify the devices and the DHCP client and
server. It also describes what configuration information is sent to the Teldat 4Ge.
Teldat S.A. 2 Introduction
Teldat 4Ge 5
The next step, once the Teldat 4Ge has a valid IP address, is to set the data backup mechanism.
The latter is performed by VLAN 463. Through this VLAN, the Teldat 4Ge assigns the public IP it has obtained to the
router's Ethernet subinterface belonging to the same VLAN and sets a new default route to redirect traffic to the 4G
network.
