I will advise you put a physical loop-back cable on the port and confirm your configuration is okay and later work with your provider.<br><br><br><br><div class="gmail_quote">On Thu, Feb 4, 2010 at 10:13 PM, Peter Petrov <span dir="ltr"><<a href="mailto:peterpet@mail.ru">peterpet@mail.ru</a>></span> wrote:<br>

Check the cable, and if you have optical E1 modems check the right configuration of the jumpers! In the past i have the same message and i fix this with right configured jumpers on modems on my side and Telco side. and what kind of E1 card you are use for this SS7?<br>
