Engineering Notes
Capacitors C1, C2 and C3 and Ferrite Beads FB1, FB2, and FB3 prevent radiated emmisions from
entering or leaving through the modem's telephone cable. They may be needed for your system to
meet FCC Part 15 Rules. These components should be mounted as close to the RJ11 jack as
possible.
The relay, K1, switches the telephone line to the auxilliary phone jack, J2, so that the phone line can be
used by a telephone handset when the modem is not active.
The XE2401L inlcudes user tranferrable FCC Part 68 Registration; however, your system design must
not introduce any characteristics which cause the Part 68 rules to be violated. Follow design rules
carefully to ensure full compliance with FCC Part 68 rules. Xecom recommends a minimum of 0.100"
clearance for tip and ring traces. Use PCB materials with a minimum rating of 94V0. This will ensure
compliance with FCC 1500V isolation requirements. If this is a problem in your design consult with
Xecom's Customer Service engineers for assistance.
