A. A center-tapped winding can be created by connecting two ends of a split center winding together on the printed circuit board. In ISDN-S applications, the primary
winding is the line side transformer winding.
B. Minimum primary inductance and maximum distributed capacitance satisfy the transmitter output and receiver input impedance requirements of CCITT I.430 for both
the TE and the NT. The maximum distributed capacitance allows sufficient margin for the capacitance of the IC and a protection diode network. It is consistent with
the overall maximum value specified and the permitted length of the basic access TE cord.
C. The maximum specified unbalanced DC current capability is based on 20 mH minimum primary OCL.
