Marconi 131-7230/03 04 – STM-1E G.703 (Type 2) tributary interface card for Marconi SDH transmission platforms. Used/refurbished, quote-only.

The Marconi 131-7230/03 04 is an STM-1E G.703 (Type 2) tributary interface card for Marconi SDH transmission equipment. This class of card provides an electrical (G.703-standard) STM-1 tributary interface, allowing a multiplexer or add-drop shelf to add or drop a 155 Mbit/s STM-1 signal over coaxial cable rather than fibre.

Marconi, whose transmission business became part of Ericsson following the 2006 acquisition, supplied this card as one of several tributary and interface variants in the 131-72xx and 131-73xx numbering family, alongside optical STM-1 and higher-order tributary cards.
