I received a number of replies from people within Cisco. Most of them pointed
to an internal cable problem and after confirming it with our vendor this
turned out to be the case. The problem was that our hardware manuals said
the cables from applique to interface board would be labelled 1,2,3 and 4,
and then gave a picture how these should be installed to connectors P1,P2,P3
and P4.

It turned out that the cables were labelled A,B,C and D, and the obvious
transformation I made was wrong. The A,B,C and D cables should be attached
to the connectors from left to right, in that order.

Everything works now. I am left with the impression however that installation
instructions for interface boards should be distributed with the interface
boards and not with the router itself. That makes it possible to change
the cabling after selling the router without inconveniencing customers.
