FIC-4BSE
Introduction FIC-4BSE, the four-port ISDN BRI interface card, 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.
Interface Attributes The following table describes the interface attributes of the FIC-4BSE.
