Alcatel-Lucent 3AL34481AA legacy SDH/PDH transmission Telecom System Card / Module

The Alcatel-Lucent 3AL34481AA is an ADM 600 interface card used within Alcatel-Lucent’s legacy transmission shelf families. Add-Drop Multiplexer (ADM) interface cards of this kind provide the connection point between the host transmission shelf and an associated ADM 600 sub-system, supporting the add/drop of traffic at defined points along the transmission ring. This type of interface card is fitted into the shelf backplane alongside other tributary, aggregate and switching cards, and forms part of the wider set of options that let operators tailor a shelf’s traffic-handling to a specific network role. As a plug-in module, the 3AL34481AA is field-replaceable, allowing maintenance engineers to restore ADM interface connectivity on an in-service shelf without a wider outage. Operators keeping legacy Alcatel-Lucent transmission equipment running in access and metro networks continue to rely on tested secondary-market spares of this kind. Tech-Star (UK-based, shipped worldwide) supplies tested Alcatel-Lucent legacy transmission spares including this ADM 600 interface card.
