I’ve the famous TCH FAIL problems in one of my sector GSM 1900. I’ve already changed all the Hardware, feeders, connectors, TMA and antenna panels but the problems still continues. I don`t know if the problem is enginnes, RF planning or some bad configuration. I`ve still measured the VSWR of the feeders and all is ok.
someone knows why this happens?
Please People, I don`t have Technnical support from Ericsson
