Alcatel-Lucent 3AL34007AA legacy SDH/PDH transmission Telecom System Card / Module Image 1

Alcatel-Lucent 3AL34007AA 140 Mbit/s switch module (K20) for the 1641SM family of SDH add-drop multiplexers. Plug-in switching card for legacy PDH/SDH transmission shelves.

The Alcatel-Lucent 3AL34007AA is a 140 Mbit/s switch module, factory-designated K20, built for the Alcatel 1641SM family of compact SDH Add-Drop Multiplexers used extensively in access and metropolitan transmission networks. The 1641SM platform supports STM-1 and STM-4 aggregate interfaces alongside a range of PDH and Ethernet tributary options, and relies on internal switching cards such as this one to route 140 Mbit/s traffic between the shelf’s aggregate and tributary slots. As a plug-in module, the 3AL34007AA slots into the 1641SM/1651SMC shelf backplane and is field-replaceable, letting maintenance engineers restore switching capacity on an in-service multiplexer without a full shelf swap. This part continues to see demand from operators keeping legacy SDH transport rings running in regional and access networks where full platform replacement is not yet justified. Tech-Star (UK-based, shipped worldwide) stocks tested Alcatel-Lucent 1641SM spares including this switch module.
