Notes:

1 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.

2. If additional componants, such as ferrite beads, are connected in series with Tip and Ring to provide additional

EMA filtering, Xecom recommends adding surge protection in front of those compannats to protect them from

dmage due to lightning strikes. Xecom recommends the Teccor Sidactor to provide this type of suplemental

protection.

3. The XE2420G includes internal circuitry to protect the modem from damage due to lightning strikes. However,

any components placed on the Tip and Ring traces will not be protected. If you add any components between

the phone jack and modem module, a surge protector such as the Teccor P3100BA Sidactor should be placed

before these components to protect them from lightning damage.
