Alcatel-Lucent 3AL34075AB 21×2 Mbit/s 75-ohm tributary interface card for Alcatel-Lucent legacy SDH transmission shelves.

The Alcatel-Lucent 3AL34075AB is a 21×2 Mbit/s tributary interface card with a 75-ohm impedance, built for Alcatel-Lucent’s legacy PDH/SDH transmission shelves. It provides 21 individual 2 Mbit/s (E1) tributary ports on a single card, terminated at the standard 75-ohm unbalanced impedance widely used in European telecom access networks. This high port-density design lets operators consolidate a large number of E1 leased-line or trunk circuits onto a single tributary slot within the host shelf, which is a common requirement on access rings carrying legacy TDM traffic such as PBX trunks, mobile backhaul links or leased circuits. As a plug-in module, the card is field-replaceable, allowing engineers to restore tributary capacity on an in-service ring without a full shelf outage. Tech-Star (UK-based, shipped worldwide) stocks tested Alcatel-Lucent legacy SDH tributary spares including this 21×2 Mbit/s card.
