ANT.:
RF antenna connectors.
For the Wireless LAN interface to work, the device must have a plug-in Wireless LAN card and the corresponding
software license. In some models, the antennas are installed as a factory setting. If your device does not have the
Wireless LAN module, you can add it later on. The manual provided will indicate how to install the module and its an-
tenna cables in the device.

1.2.2.1 BRi Connection
The BRI interface has a 4 wire RJ45 female connector in order to connect to the S bus coming from the ISDN net-
work terminator (NT1 or TR1).
In order to connect, use the cable with RJ45 male connections provided with the device.
Passive-Bus terminal resistances
The ATLAS 50 has 2 internal jumpers to configure the S-BUS terminal resistances.
To access the jumpers (P1 and P2), you need to open the open the lid or top of the device. The jumpers are located
next to the Power connector (S1) and the BRI (CN1) connector. To activate the terminal resistances, you need to po-
