Please note the "accepted practice" phrase. The reason I posted
the note was to find out if other people knew of implementations
that did the same thing.

After talking with my Corporate Telecommunications Department, I
understand that this is a bug with the particular version of firmware
that I had. However, this was the first node of many that I need
to set up and I was shocked to find that my assumptions were wrong.
The 0xCC flag is important when nodes need simultaneous X.25 and IP
access.
