   There's a bit of confusion here.  The V.42 spec includes, as an annex, MNP 
up to service class 4.  The V42bis spec, as far as I know, doesn't necessarily 
imply MNP5 compatibility, though most V.42bis modems do offer it.

   Naturally, when a V.42bis modem calls an MNP-only modem, it must fall back 
to MNP protocols, including MNP data compression... and therefore loses the 
advantages of V.42bis data compression.
