    Dear All,
    1st of all this forum is a very good place and i have learnt a lot of things from here.Thanks to all you of you for this.
    I have one question during drive test when block call occure it states three reasons
    1-“No alerting or connect”
    It means congestion in network.because i have noticed during CQT when traffic is high on site and block calls happen then it is stated as “No alerting or connect”.but some people say it is due to network problem.
    2-“No traffice channel asignment”
    does it mean TCH assignment failure or TCH congesttion.
    3-“Immidiate assignment failure”It is mostly due to sdcch drop or sdcch congestion.
    it can be due to hardware problem,bad quality or interference.
    Am i right in above statements?
    Waiting for kind response.
