Alcatel-Lucent 3AL34281AA 140Mbit/STM-1 tributary interface card for Alcatel-Lucent legacy PDH/SDH transmission shelves.

The Alcatel-Lucent 3AL34281AA is a 140 Mbit/s and STM-1 tributary interface card used within Alcatel-Lucent’s legacy PDH/SDH transmission shelves. It terminates tributary traffic at both the 140 Mbit/s PDH rate and the STM-1 (155 Mbit/s) SDH rate, giving the host shelf flexibility to drop either plesiochronous or synchronous circuits from the aggregate signal depending on what the connecting network segment requires. This dual-rate capability was particularly useful during the industry’s staged migration from PDH to SDH, when access and metro rings often had to interwork both signal types simultaneously. As a plug-in tributary card, the 3AL34281AA is field-replaceable and can be swapped into a live shelf during maintenance without disrupting traffic on adjacent slots. Tech-Star (UK-based, shipped worldwide) supplies tested Alcatel-Lucent legacy SDH tributary spares including this card.
