Just took on a duplex 330a, single riser. Top floor quit taking calls, bad board. changed board out, worked for a week, then have up. Board tested good on another floor. Car will not go up if lower floor switched to mimic top floor. Redid the 2 cat ends, no change. Cable test ok with lan tester. Controllers lon tests ok. Am I missing something? Did work briefly while had hall station off for testing, then nothing. Thoughts? Ideas?
