RS960 Interface (ENSS, “End Node Switching System”)

The routers today that are available to handle the full routing table are: .. IBM ENSS w/ 64Mb .. — https://www.ripe.net/ripe/mail/archives/lir-wg/1995-August/000753.html

These systems were based on a Powerserver 930 first generation RS/6000 server, configured with special “RS960” interface boards. Each of the RS960 boards has two i960 CPUs, runs a stripped down AIX kernel, and is a fully functional router. Each “board” actually consists of two circuit boards: a base (router), and a second board which interfaces to a specific network interface (ethernet, FDDI, v.35, HSSI). — https://www.rcsri.org/collection/nsfnet-t3/

Regarding the HSSI version, ”They didn’t make a lot of these”.

P4200

October 1985 (source)

“The p4200 could interconnect its new ProNET-4, and its ProNET-10 and -80 networks as well as Ethernet LANs and public WANs”

“The p4200 is considered the first commercially available multi-protocol router. (The use of the term router came only over time; finally taking hold in 1987. The p4200 was known first as a LAN gateway then a Gateway router and finally Router)”
