You need more than the four built-in Ethernet ports? I believe the uPIMs are dual PCI/PCI-E, and use a switch chip to provide additional Ethernet ports with flexible mapping. If you don't have a need for hardware (wire speed) L3 on your LAN, they're a tempting way to cram Ethernet switching functionality into the router box. The J2320 has only PCI for PIM connectivity, but 100Mb/s should be no problem. Now you also have the choice of JUNOS, ScreenOS, and "JUNOS Software with Enhanced Services" (JUNOS with ScreenOS features but [from a quick review of the docs] minus the licensed extras). Peter E.
