Er det noen som kjenner til dette? Ville jo foreslått "dobbelttilkoblet", men det er det null treff på.

Bare for litt sammenheng:
"Serial device routers are typically dual-connected to the Ethernet core for resilient connectivity in differing industrial applications. One common topology is dual-connected into two different Ethernet backbone rings for use in architectures such as large power substations with IEC 61850 designs that require redundant core networks. Another topology is a resilient Ethernet-based edge collector ring connecting several dispersed serial edge devices that may be cost-effective in highly distributed applications such as pipelines, tunnels and wind farms."
