The micro-filters
Only some DSL operating modes (eg, G.Lite or ITU G.922.2) permit the use of basic service
devices (PSTN or ISDN) directly connected to the same line by using a device called “micro-
filter”. This device ensures that the DSL signal does not reach the basic service device and that
undesired signals generated by the device do not interfere with the DSL signal.
A typical installation with micro-filters is shown in figure 15.

WWAN Antenna Connection (Cell connector)
The Teldat V router has three connectors to connect 3G antennas. To assemble and disassemble
the antennas, simply screw them into the connectors labeled
Cell
on the front panel of the router.
The installation of these antennas in the Teldat V router is essential in order to improve the
quality of the signal received and transmitted by the cellular model.
So that the Wireless WAN interface is operative, the device must have a plug-in Wireless WAN
card and the corresponding software license. If your device does not have the Wireless WAN
module incorporated, you can obtain this later on. The manual accompanying this module will
indicate how to install it as well as the corresponding antenna cables in the device.
To obtain good performance, the router should always have the WWAN antennas installed.
