Chapter 12: Configuring the ISDN and analog interfaces in detail

EN
Plug the cable in again and start the device.
A change to the software configuration is also necessary if the ISDN
interfaces are to be set to a different mode. If devices are to be con-
nected to an ISDN interface which is set differently to its default set-
tings, the supplied adapter must be used. This adapter serves to cross-
over the contacts in the ISDN interface.
12.3
Protocol setting
Parameters for the ISDN interfaces are entered into LANconfig in the config-
uration area 'Interfaces' on the 'WAN' tab. Under WEBconfig, Telnet or SSH
client you will find the settings for the ISDN interface parameters under
Setup/Interfaces/WAN
.
