That's been the general theme with operators who are traditionally Layer 
1 or Layer 2 service providers, looking to dabble into packet switching. 
It often makes sense for them to speak to their Transport vendor, as 
their gear is already an installed base.

Two or so years later, those operators will be ripping those Transport 
boxes out and replacing them with more traditional packet switching 
gear, as you did as well.

Transport vendors continue to push their boxes as being MPLS-capable 
routers. It tends to be a "tick the box that we had that conversation 
this new year, make it last at least 3 seconds, and then carry on with 
real talk" situation :-).

Mark.
