129FIC-4BSEIntroductionThe 4-port ISDN BRI interface module (FIC-4BSE) transmits, receives, and processes four channelsof 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 BRIS/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.Interface specificationsTable 176 Interface specificationsItem DescriptionConnector RJ-45Number of connectors 4Cable ISDN S/T cableProtocol & standard ITU-T I.430, Q.921, Q.931Operating mode • ISDN dial-up• ISDN leased lineSupported service• ISDN• ISDN supplementary services• Multi-user number• Sub-addressing• BackupJumper settingsThe FIC-4BSE uses jumpers to set matched resistance for ISDN BRI S/T interfaces. The use of100-ohm resistance on an ISDN BRI S/T interface depends on jumper settings. The following figureshows the jumper settings, where all the ISDN BRI S/T interfaces are using 100-ohm resistance.Figure 146 Jumper settings of the FIC-4BSE (example)The following table describes how to set jumpers.S1S2 S3S4 S5S6 S8S72 30 1
