Your E1 is down. It may be a cabling problem, or perhaps the circuit is using CRC4.

how you know that?

plus I want to be sure where is the problem exactly?

if you need any debug plz tell me?

Thanks alot & appreciate your help

See all the errors in show controllers E1, these have to go away for the circuit to work.

You don't need any debug, just correct configuarion and cabling.

After thta, if still doesn;t work, it's SP resposnabiity to fix, even if they say it's ok.
