222CHAPTER 4: FLEXIBLE INTERFACE CARDS

The signaling on the ISDN BRI D channel is processed separately by CPU.

The BSV interfaces support remote power supply and can be connected to ISDN phones directly.

The FIC-2BSV/FIC-4BSV is dedicated to voice applications, which is different from the BS interface cards where BRI data applications are supported.

Interface Attributes The following table describes the interface attributes of the FIC-2BSV/FIC-4BSV.
