Notes:
1 FB1 and FB2 are ferrite beads which may be required for EMI filtering in your system. Without these compo-
nents you may experience unintended radiation when the telephone cable is attached to your system. We
recommend selecting components such as the TDK ACB2012L-120 which provide a minimum of 100 ohms of
impedence at frequencies above 100 MHz.
2. C1 and C2 are high-voltage capacitors which may be required for EMI filtering in your system. Without these
components you may experience unintended radiation when the telephone cable is attached to your system. We
recommend selecting components such as the Panasonic ECKDRS471. This 470 pfd, 3000 volt capacitor will
direct the high frequency harmonics to the system ground. These capacitors must be rated at a minimum of 1500
volts to maintain the isolation required by FCC Part 68 Rules.
