Strange traffic on a Cisco 1841 router port

A friend of mine sent me an interesting graph:

This is the traffic on their router WAN interface, which looks towards their ISP. They should have 10Mbps/10Mbps connecton. However, according to graph, it looks like it's 10Mbps for both upload and download

Any ideas, what might cause this?

what type of connection is it? Ethernet handoff?

Half duplex if it is Ethernet?

inbound traffic just not pushing the utilization that high?

That's my thought, as well. If this were full duplex you wouldn't see a drop in input the directly corresponds with an increase in output. But if it's half duplex, it's a one-way street and something has to give. Make sure both sides of that connection are set to autonegotiate.
