  Well as I recall, Field1 of 00 means SDLC so that is correct.
  Field 2 of C1 means the Station address is C1, also correct.
  Field 3 0 means Leased line
          1 Means Full Duplex
          1 Means Point to Point
          0 means NRZI
          and the others don't matter much.

  Soooo, the config parameters you list are apparently correct.

  So it appears to be in the modems and I am clueless on those.  It would appear
that because you get some flickers the system is attempting communication but
some response by the modem is NOT what is expected so the line failes.  7855's
should also work just great in this environment.  One thing to check is if the
line is a 4wire or 2wire.  The modem needs to know this.  If it is a two wire 
you
may need to change the 5294 and the AS/400 to *HALF duplex.

  Sorry but that's about all the gray matter is giving up this evening!
