Hi,
I am getting the results below when I do a E1/T1 diagnostics.
I need to know what causes " E1/T1 link test failed " error(in red color below) . So that I can fix it.
I noticed this when users get a busy tone, when trying to make call through the E1.
There was no record of active calls at the time.

Test successful.

Thanks
