I agree that, insofar as possible, you should try to migrate what you can away from the 3745s. CCL is available to support whatever you cannot realistically convert to use OSA Express and TCP/IP (perhaps with Enterprise Extender). I think CCL supports Token-Ring -- please double check me on that -- on mainframe models that support Token-Ring attachment. However, you may wish to migrate the physical network at the same time you migrate from the 3745s, if possible. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
