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 ROE of the feeders and all is ok.
someone knows why this happens?
Please People, I don`t have Technnical support from Ericsson
I’ve nokia system in BSS part in my network and some BSC’s have TCH A_IF Fail for most of cells. for this reason these cells have high TCH drop because of a interface fail.
Please give me a solution for solving this problem.
I`ve configured the most of my Cells in the same way. I have configured the first dTRU how Channel group 0 and it’s asigned how TCHControl. When this dTRU down, the TCHControl loss de sincro. I don’t know if this configuration is working in good order.
