The world's first STM-1/OC3c link. It involved Sprint and TELE2.
There are only two cable systems that support SDH/SONET. We also wanted a cable system that was self-restoration. That made only one available to us.
There are 20Mb of buffers with an RTT 98MS.
There were eight different operators.
The IP over SONET makes many of the SONET monitors think the line is in error.
ICM-PEN 11 and ICP-PEN 12 are connected to the STM primary and protect respectively. Those routers are connected to each other on FDDI (along with some others).
On Stockholm, it is similiar.
Fiber Path : NJ/NY/UK/BE/NL/DK/DK/SW
A standard test set can't be used to test this since the framing does not look like the router's framing.
