2928 - Using WAN2 SFP+ port to BTnet ADVA issue

Hi,

Has anybody successfully managed to setup a 2928 using the WAN2 SFP port to a 'wires-only' BTnet service that terminates with an ADVA FSP150 unit?

We've tried multiple 1Gbps SFP's with no joy, set to either 1G or Auto-Negotiate. The 'Access' side LED remains red.  However if we take the same service through a media converter and into the RJ45 WAN1 port it comes up (green) straight away.  (the combo ports that are set to active are the two SFP+'s ports).

We do have a support call open with Draytek already but would just appreciate if anybody else has already got this working.

Thanks,
Ian
