Jumper settings
The FIC-4BSE uses jumpers to set matched resistance for ISDN BRI S/T interfaces. The use of 100-ohm
resistance on an ISDN BRI S/T interface depends on jumper settings. The following figure shows the
jumper settings, where all the ISDN BRI S/T interfaces are using 100-ohm resistance.
Figure 122 Jumper settings of the FIC-4BSE (example)
The following table describes how to set jumpers.

Jumper settings & description Default
Interface 0
S2
• To use a 100-ohm matched resistance for data transmission,
place the jumper over pins 1 and 2.
• To do otherwise, place the jumper over jump pins 2 and 3.
• See Figure 122.
The jumpers are
placed over
jump pins 2 and
3, meaning
100-
ohm
matched
resistances are
not used.
S1
• To use a 100-ohm matched resistance for data receiving, place
the jumper over jump pins 1 and 2.
• To do otherwise, place the jumper over jump pins 2 and 3.
• See Figure 122.

S3
• To use a 100-ohm matched resistance for data receiving, place
the jumper over jump pins 1 and 2.
