Wavecom Supreme with Ethernet access?

I understand that Waveom has released CPU based Wavecom Supreme.

I’m looking at developing an application that can access LAN via ethernet and at the same time execute AT commands on the GPRS module. I’ve searched Wavecom website and the internet for more information whether this can be done with Wavecom Supreme, but everything looks sketchy at the moment; Wavecom’s website just mentioned the availability of a IESM Ethernet expansion card and i have not seen if this card is already in the market. Also, whether the real-time OS will be able to access or connect to the LAN via this ethernet card.

Any suggestions will be welcomed. Thanks.
