Prices of terrestrial SDH/SONET cards are very low for transport providers.
For customers I believe there is a greater divergenc between the Ethernet and
SONET/SDH costs.
A strong hunch based on what clients tell me Cisco charges for SONET/SDH
interfaces.
I doubt a lot of people would

Hate to say it, but also some of the cost on the circuits can be blamed

The reality is that is an SDH/SONET backbone underlying most of these
Ethernet networks.
That may be so (however, numbers for the national provider I work for do
not tend to bear this out). But does it matter? People presumably use
Ethernet because it is inexpensive, easily available, well
