Jumper Settings The MIM-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.
