> red alarm usually means there's no clocking signal. > check all your cables (crossover vs straight through) > As far as the cable goes, this is a bit complicated. The way it works is the telco delivers a fibre optic cable to the floor and the fibre terminates on a fibre optic multiplexer. Then the multiplexer is connected to a Fast Ethernet to E1 converter which has a RJ45 port. We then connect this RJ45 port to the TE412P port. Anyway what you said is still a good point - I will try replacing the straight through cable with a crossover and give it a go. > if the cable's good. call phone company and complain. > in my experience 9 out of 10 time we have to call > phone company and complain. > How should we complain? Are there any technical details we need to show them? It is a different country though. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
