Hello users,

I have a Digium Te235 and asterisk 13  which have worked well with 1 carrier but we have failed to add a 2nd carrier. The second telco brings their E1 line over finer, terminated in a RAD modem and they give me ethernet to the E1 card. It's the first time i am having install such a solution, which ideally would be not a big problem.


However, The  physical layer has failed to come up! I have tried the same setup in an Alcatel OmniOCX and it works well. I can confirm that the port is also well configured because when I interchange the cables (with the exiting cable from the other telco), the alarm clears emmediately for the 1st telco and becomes RED for the 2nd telco. A loop also clears the alarm on both ports.


The telco has told me to make sure that Line Impedance is 120 ohms but There's no where to set that and when I was reading, I was told that E1 is already 120 ohms so no need to change anything.


Has anyone here experienced this?  What other things can I try?


Thank you!


Regards,
Tim
