Marconi 1HAM60782AAS: user alarms LTU, SMA-1/4 Series 3.1, for Marconi SMA SDH multiplexers.

The Marconi 1HAM60782AAS is a user alarms line termination unit, marked SMA-1/4 Series 3.1, for Marconi’s SMA range of SDH add/drop multiplexers. It collects external user alarm contacts and reports them into the shelf’s alarm and management path, its own marking confirming compatibility across the SMA-1 and SMA-4 node variants within the Series 3.1 generation.

Marconi’s SMA family, inherited from GPT and Plessey, is a subrack of plug-in units: line termination units, alarm and management cards such as this one, optical STM interfaces, a system controller and power feeds. Marconi’s 2006 collapse ended factory support, so every SMA site still in service is maintained from secondary-market spares.

Tech-Star (UK-based, shipped worldwide) holds SMA cards for maintenance and expansion projects. Please contact our sales team to confirm compatibility with your specific SMA-1/4 configuration and for current stock and pricing.
