Preliminary
Figure 101
For handling higher electromagnetic compatibility (EMC) requirements, additional effort
in the circuit design may be necessary, e.g., a current-compensated choke of 470 H in
the Ring/Tip lines.
This circuit senses the ring current in both Tip and Ring lines. Longitudinal influence is
cancelled out. This circuit therefore is recommended for long line applications.
