Anyone?Daniel Partridge A filter isn't going to do you any good, since there is nothing for you to filter. Most often crosstalk happens between adjacent non-twisted pairs. Examine the cable in your house. If the pairs are not twisted pairs replace the cable. In the U.S. the non-twisted type of cable most often contains 4 wires: red, gree, yellow, black. Red/Green is your first line, and Yellow/Black is the 2nd. The twisted cable will most commonly have pairs of opposite colors. Pair 1 = white/blue and blue/white. Pair 2 = white/orange and orange/white. Ron
