Dhananjay kumar dhananjay.cse at gmail.comDear Holger, Many thanks for your mail. Based on your suggestion we did experiment on B210 with osmo-stack for run-time network parameter control from VTY. - Parameter change related to MS takes effects when New MS is latches to Network. Example : MS_Max_Power - Parameter change related to TRX takes effects when TRX is re-started. Example : RF_Lock 0 - Parameter change related to BTS takes effects when BTS and TRX is restared. Example : Band/ARFCN One more query regarding loop-back call : "bts <0-0> trx <0-0> ts <0-7> lchan <0-1> loopback", we tried this command to start loop-back call once MS is registered to the network. But we are not seeing any loop-back call happening in nitb and osmo-bts logs. Could you please let us know more on this loop-back call. How we can use this ?
