Alcatel-Lucent 3AL34280AAAE02 legacy SDH/PDH transmission Telecom System Card / Module

The Alcatel-Lucent 3AL34280AAAE02 is a tributary interface unit built for Alcatel-Lucent’s legacy PDH/SDH transmission shelf families. Tributary cards of this type sit in the drop-side slots of the host shelf, terminating individual circuits so they can be added into, or dropped out of, the shelf’s aggregate SDH signal. They work alongside aggregate and switching cards within the same chassis to keep an access or metro transmission ring in service, and are a routine field-replaceable spare for engineers maintaining these older but still widely deployed rings. As with other cards in this product family, the 3AL34280AAAE02 is designed to be swapped into a live shelf without disrupting traffic passing through adjacent slots, which keeps maintenance windows short. Operators who have not yet migrated away from Alcatel-Lucent’s legacy transmission platforms continue to rely on tested secondary-market tributary spares of this kind to keep circuits running. Tech-Star (UK-based, shipped worldwide) supplies tested Alcatel-Lucent legacy transmission spares including this tributary unit. Contact us to confirm exact shelf compatibility before ordering.
