MOUNTING AND CONNECTING THE DEVICE
- VDSL interface
Use the supplied DSL cable for the IP-based line to connect the VDSL interface and the provider’s telephone socket. For more infor mation, please contact your Internet service provider. - Ethernet interfaces
Use an Ethernet cable to connect one of the interfaces ETH 1 to ETH 4 to your PC or a LAN switch. - Analog interfaces
Connect analog terminal devices to the analog interfaces either directly via RJ11, or with the help of the enclosed TAE adapters. Further adapters are optionally available. - Configuration interface
Use a serial configuration cable to connect the serial interface (COM) to the serial interface of the device you want to use for configuring / monitoring (separately available). - ISDN interfaces
ISDN 1:
Internal (NT) or external (TE) ISDN bus. This feature is controlled by LCOS.
ISDN 2:
Internal (NT) ISDN bus.
100-Ohm resistor for line termination is switchable in LCOS. - USB interface
You can use the USB interface to connect a USB printer or a USB memory stick. - Power
After connecting the cable to the device, turn the bayonet connector 90° clockwise until it clicks into place.
Use only the supplied power adapter.
