8.14.3 Internal DIP Switch
The purpose of the internal DIP switches in RT-FIC-4BS is to set the matched
resistance of the ISDN BRI S/T interface. The setting of the switch (DIP S1) decides if
the matched 100-ohm resistance on the ISDN BRI S/T interface is to be used. The
following figure shows the default setting of the switches, in which case all the four
channels of ISDN BRI S/T interfaces are using 100-ohm resistance.
