:O.K.  I have spent quit a bit of time hashing this out with many different
:people, and this is how it looks to me:
:
:1. You CAN send TCP/IP over SNA -- in SOME cases.
:   To attach SNA to TCP/IP (using AVAILABLE hardware/software) you
:   MUST have a host (i.e. a 370) and a host adapter (I think it is an
:   8232).  To route TCP/IP over SNA would look as follows:
:
:workstation---8232--370====(SNA NETW)===370--8232---workstation
:
:There are plans involving RT's and SDLC links, but they do not seem
:(to me) to really be routing TCP/IP over an SNA network.
:
:2. The "normal" IBM communications hardware (3705, 3174, etc) do
:   not support TCP/IP connections.  You have to attach to a host
:   at each end of your link.  Future versions of the 3705 and 3174
:   will probably support TCP/IP, according to an IBM employee
:   I met at an IBM class, but that is "unofficial."
:
:3.  We don't like the above.  We are looking at multiplexing TCP/IP and
:    SNA over our existing lines, or using an X.25 service, or
:    using other alternatives to running TCP/IP over SNA.  If you find
:    a better solution, PLEASE POST!  (Other people seem to be interested!)

Try talking to your local NCR Comten representative for solutions to
SNA and non-SNA networking problems.  NCR Comten manufactures IBM
plug compatible SNA front ends offering both channel and SDLC link
attached connectivity.  NCR Comten also has a wide ranging offering
of connectivity products for non-SNA networks,  connecting to both
BSC and X.25 hosts.

NCR Comten will shortly be offering a TCP-IP product.  Initial
link connectivity will be via X.25,  but an Ethernet interface will
also be provided.   Your NCR Comten representative should be able
to provide you with availability dates.
