Hi,
This is something that we are pushing for internally, I suggest that you push your commercial contact, be it direct account manager or distributor that we can add your name to the list of people who want this on the WP. Otherwise the general option we push people towards is the HL series which are designed as bit pipe modems and are pin to pin compatible with WP designs (and vice versa) through the CF3 strategy/scheme.
Regards
Matt
