T320 Core Router is designed for use where rack space is at a premium and a wide range of interface speeds are needed.
Each T320 router can support up to sixteen 10-Gbit/s ports (OC-192c/ STM-64 or 10-Gigabit Ethernet) while allowing lower speed connectivity down to channelized increments within the same chassis.
Those include ATM (Asynchronous Transfer Mode) and SONet (Synchronous Optical Network) interfaces at OC-3 (155M bit/s) and OC-12 (622M bit/s), as well as Gigabit Ethernet.
With scalable memory and storage media, JCS1200 provides up to 12 routing engines in a compact one-quarter rack chassis.
[11] The T-series features include MPLS Differentiated Services (DiffServ-TE), point-to-multipoint label-switched paths, nonstop routing and in-service software upgrades (ISSUs), hierarchical MPLS, and service delivery coupling with the Juniper Networks JCS1200 and the Partner Solution Development Platform (PSDP).
