The KEYMILE ROFBU 367 163/1 is a plug-in card for the Keymile UMUX multi-service access and transport platform, part of the same ROFBU 367 xxx/1 part-numbering series used across UMUX traffic and interface units. This part number is confirmed to exist in industrial hardware distributor catalogs (hardware revision R1A referenced), but its specific functional designation (the 5-letter function code) was not found in publicly available sources or reseller listings at the time of this search. UMUX is a carrier-grade multiplexer platform used by dedicated network operators such as utilities, railways, and airports. Keymile was acquired by ABB in 2017 and the UMUX range was later discontinued; this card is now sourced mainly as a refurbished or pulled spare part.
