If called without options, the packages globally sets 'framesep', 
'framearc' and 'linearc'. You can disable this by using the 'notelegant' 
option (see the package documentation).

This, however, disables also the round corners of the frame elements.

I think most elegant would be to define a psstyle e.g. SigsysFrame 
within the package and use this for the components instead of globally 
setting frame parameters.

You may suggest it to the author (I put him in the CC in case he does 
not read the mailing list). Until then you can use

\newpsstyle{SigsysFrame}{framesep=0.125, framearc=0.25, linearc=0.1}

Additionally you could use
