The redbook designed to deal with matters arising from the withdrawal of the 3745 Communication Controllers is the following: IBM Communication Controller Migration Guide http://www.redbooks.ibm.com/abstracts/sg246298.html > We currently use DLSW and Cisco routers to do the SNA/polling of the old controllers. Since you mention "polling" this could be more clearly - if longwindedly - stated as "We currently use DLSW supported within Cisco routers to mimic the operation of SDLC lines so that the Communication Controller continues to operate as the primary SDLC station and the "LU0" controller continues to operate as the secondary SDLC station. This means the Communication Controller imagines it is polling the "LU0" controller directly and the "LU0" controller imagines it is being polled directly by the Communication Controller whereas, in fact, the polling performed by the Communication Controller is thrown away by the adjacent node running DLSw and the node running DLSw adjacent to the "LU0" controllers performs the polling of the "LU0" controllers." You see it takes quite a lot of explanation to justify mentioning "polling of the old controllers". This only indirectly involves SNA since SDLC is just one of many data link control protocols which SNA can use and, although I can't quote an example, SDLC could be used by networking protocol suites other than SNA. You didn't say what the "LU0" controllers were. Since "SSFCU" may be "Security Services Federal Credit Union", this hints that you are specifically an "organisation" (.ORG) in the "finance" sector, I could guess that the so- called "LU0" controllers could be 3600s - you did say "old"! - or 4700s or some lookalike. > I have been tasked to move our old SNA/SDLC communications controllers to a Windows communications server environment. This smells of "prejudice", in that the "solution" appears to have been decided before the "problem" has been understood and analysed. Is this a case of the "suits" dictating technical solutions to the technicians? One possible solution - based on "technical" considerations - is to continue to use NCP while removing the dependency on 3745 communication controllers. This could involve no changes at all to the presumably distributed "LU0" controllers and their adjacent DLSw "routers". Assuming this "solution" looks appealing after having read "IBM Communication Controller Migration Guide", you should then read the following redbook: IBM Communication Controller for Linux on System z V1.2.1 Implementation Guide http://www.redbooks.ibm.com/abstracts/sg247223.html You will see that you will need to change your NCP - and VTAM - definitions as they relate to the distributed controllers somewhat. The major requirement with the CCL product is that you have the skills to install and operate a LINUX operating system and associated programming on the zSeries platform. That apart, your existing skills with VTAM and NCP are preserved. I am also assuming that you have the hardware available to set up an OSA in OSN mode, probably so highly desirable as to be required. The CCL solution has the highly appealing quality of kicking sand in the face of the "Windows" solution in that it uses an operating system platform which kicks another part of the anatomy even if it is required in the case of CCL to run on a zSeries platform rather than an Intel platform.
