[nsp] Gigabit Ethernet over SDH/Sonet

[Eoin Kenny]

Thanks for all the suggestions.
At the moment my GE circuit is finally up. The provider did a cold 
restart of the STM64 ring!!! and our link came straight up.

As for 1310nm Mikael you are wright the SDH ring has 1310nm interfaces. 
The DWDM ring converts from our 850nm to 1310 at the providers site.

Physical loops on the DWDM and in front of the GSR also worked!

I have asked for a full explanation so if I get more information I will 
let the list know.

Many thanks
