So now I have what I need as far as parts and sourcing.

I think I'll settle on the MH88612 from Mitel as the SLIC.

I'm also going to get a couple of MT8808 8x8 crosspoint switches.

Both of these are available from Electrosonic here in Ontario.

MH88612  $16.87CDN
MT8808   $10.73CDN

Now, as I understand it, I would use the SLIC chips at the CO side of
things.  Would this be correct??  Or is there another interface chip that I
may need??
