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.
