Sybase datasource via DBconnect on BW 3.1

Has anyone any experience on using DBconnect to integrate a Sybase 12 database as a new datasource?

If so, any hint on how to make it works as sybase is not mentionned as possible datasource in the SAP DBconnect documentation on:

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/biw/s-u/transferring data with db connect.pdf

I am working with BW 3.1 so I guess that the new JDBC base module called UDconnect is not compatible with a BW 3.1 ?

thanks for sharing your experience,

David
