Oddly enough, the original FiOS STBs were made by Motorola. Not sure if there is any connection between the two labels. Even back then (2007) Verizon used Digicon compression connectors.
It is a stretch, but Arris/Digicon is a division of Commscope, which absorbed the Systimax structured cabling product line from Avaya. In a way, that would make Arris/Digicon a distant relative to the Western Electric nameplate. Don't know if that figured the selection of Digicon by Verizon.
