FIC-4BSE

Introduction

FIC-4BSE, the four-port ISDN BRI interface module, transmits, receives, and processes four channels
of ISDN BRI S/T data traffic on ISDN BRI S/T interfaces.

The FIC-4BSE differs from the FIC-4BS only in the way they set matched resistance for an ISDN BRI
S/T interface: the FIC-4BS uses jumpers while the FIC-4BSE uses DIP switches.

The FIC-4BSE can work in dial mode or leased line mode.

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.
