Marconi 131-8681/73: STM-4 interface card for Marconi MSH SDH systems.

The Marconi 131-8681/73 is an STM-4 interface card, part of Marconi’s MSH family of SDH digital cross-connects and multiplexers. It carries a 622 Mbit/s circuit into the shelf.

The MSH range (MSH64C, MSH80, MSH84 and MSH86 among the variants) is built around a switching matrix surrounded by tributary and aggregate interface cards at the STM-1, STM-4 and STM-64 rates. Marconi’s 2006 collapse ended factory support, so the installed base is maintained from secondary-market spares.
