UBR10k SPA-1X10GE-L-V2 LAN-PHY??

Ok we have a weird one. We are trying to upgrade to a CWDM 10gb ethernet link to the UBR.

This is being fed by a Cisco 6504 Core router with 10gb cwdm interface. The link is Up/Up but WILL NOT pass traffic. If I put IP's on both sides I can ping the local but not the remote. When looking at the stats on the interfaces if I Ping from the UBR the 6504 counters don't increment, if I ping from the 6504 the ubr counters do increment. So the UBR is hearing the 6504 but the replies are failing. It was brought to my attention that there is a WL version of the SPA and it can do WAN-PHY as well as LAN-PHY, but the L version is only LAN-PHY supposedly. I have no ability to configure the card but it appears they wont talk. Thoughts? Ideas? Here is an article I found that sort of addresses the issue http://alexey.mezhuev.com/?x=entry:entry190116-194333
