Re: XTB-II 2-Phase Version

["Jeff Volp" <JeffVolp@xxxxxxx>]

That function is already covered by several different active
coupler/repeaters.  SmartHome also makes a plug-in module that works that
way, but it doesn't have as much drive as the XTB.

The XTB was really designed to increase the output of a PSC05/TW523.  A good
passive coupler is still needed when X10 devices are on both phases.  Since
the optimal location for the XTB is near the distribution panel, offering a
version with the coupler built in seemed worth doing.
