Nokia HDAD2-A high-order add-drop unit for Nokia SDH/PDH multiplexer platforms.

The Nokia C71770 B02 is an HDAD2-A card, a high-order add-drop plug-in unit from Nokia’s legacy optical transmission equipment range. Like other add-drop cards, it operates within an add-drop multiplexer shelf, inserting and extracting traffic at an intermediate network site.

The “high-order” naming indicates this unit works at the higher-order multiplexing level, handling larger aggregated traffic units rather than individual low-order tributaries. High-order add-drop cards typically work alongside lower-order tributary and line cards in the same shelf to build a complete ring or linear add-drop configuration.

Please confirm shelf type and slot fit before ordering, as high-order add-drop card generations vary across equipment ranges. Tech-Star (UK-based, shipped worldwide) checks every module before it ships. Get in touch to confirm compatibility with your Nokia system.
