You are right. The 9134 is very similar to the 9124, both being built from a switch on a chip design. In fact, they both use same kickstart and system image names. Neither support IVR, and this will not change as chipset was never designed to support IVR. They are meant for small installs or on edge of large installs (can have IVR on a core 92xx or 95xx). Unlike the 9124, the 9134 will be qualified for FICON.
