I'm not familiar with 217 but have used Bellcore 332
for a while.  Even copied the charts from 332 into an
Excel spreadsheet to crosscheck the Relex software.
Then used the Relex software.  Can change all sorts
of parameters on the spot.  If you've got a little
time, then just copy the charts out of 332 and fo
it by hand which really isn't that difficult.

The 332 way is very easy.  Pay $150 for the standard,
identify the FITs for each component, it's a snap.
