J-series
From JuniperClue
Low-end routers (8-1000Mbps) running a slightly cut-down version of JunOS (missing a few features such as Logical Routers). All have the ability to have recovery/upgrade images and configurations pulled off USB flash drives from front-mounted USB port.
Earlier J-Series products had a complex licensing regime, where individual ports would be unlocked with a software license, and some features such as DLSw were add-on licenses. Changes in 2006 and 2007 have meant that only "advanced BGP" (> 20 peers) and J-Flow features still require licensing.
Newer J-Series routers contain a TDM-backplane, and support a range of Avaya voice equipment, including a locally-survivable media gateway, ISDN BRI, T1 voice and FXO/FXS analogue voice ports. Currently these cards are managed with a local CLI, not via JUNOS, and they are only available from Avaya, not direct from Juniper.
Newer J-Series routers also share common hardware platforms with the SSG series of UTM firewalls - J2320 is SSG320M, J2350 is SSG350M, J4350 is SSG520M and J6350 is SSG550M. A seperate license of the software image can be used to switch between the two operating systems.
