Good day!
I'm working on the BreezMAX 3500 system. At last time I began to notice that Uplink SNR parameter of SU, that connected to one of sector, may go down automatically. However RSSI and all Downlink Params were remained unchanged.
When I reduce Otput Power on the ODU of this sector even on 1 dBm, Uplink SNR Parametr go up. If I increase Otput Power the Uplink SNR is going lower and lower...
Cable, that connecting ODU and AU card was changed, but it not take any effect. RF cable is doesn't change, because it very far. ODU also doesn't change.
Tell me please, in connection with which this can occur. Thanks.
