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 a Marconi SDH transmission system tributary interface card, identified in Marconi parts records as an STM-1E G.703 (Type 2) tributary unit. This class of card provides an electrical (G.703-standard) STM-1 tributary interface for Marconi SDH multiplexer and add-drop platforms, allowing a 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 interface card across its SDH product range as one of several tributary and interface variants available for a given shelf, alongside optical STM-1 and higher-order tributary cards from the same numbering family. The exact host shelf and platform for this specific card is not confirmed and is not stated here as fact. Tech-Star (UK-based, shipped worldwide) stocks used and refurbished legacy telecom transmission hardware including this and related Marconi SDH cards.
