10.5. AM-Band Interference
In certain areas, AM-band interference causes poor connectivity rates and error rates. A good EMI common-mode
filter may be necessary in some situations. An example of an off-the-shelf unit designed to plug directly into the
phone line is the Coilcraft TRF-RJ11, which can be used for debugging or fixing problem locations.
