The reference point of the line interface on the BRI2/4 cards is Point S/T (Dose not support U point). and supports External call
mode and internal call mode as operating mode.
During internal call mode, PSB21150 (Infineon) is installed as ISDN basic interface IC for BRI2/4. 
For mode detailed specifications, refer to PSB21150 data sheet.
