Alcatel-Lucent 3AL34731AA 1641 140Mbit/STM-1 bi-directional tributary card for Alcatel-Lucent legacy SDH transmission shelves.

The Alcatel-Lucent 3AL34731AA is a 140 Mbit/STM-1 bi-tributary interface card built for the Alcatel 1641 family of SDH transmission shelves. It provides bi-directional tributary interfacing 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 on the same tributary card, depending on what the connecting network segment requires. This dual-rate, bi-directional capability was particularly useful during the industry’s staged migration from PDH to SDH transmission, when access and metro rings often had to interwork both signal types on the same shelf. As a plug-in tributary card, the 3AL34731AA 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 1641 legacy SDH tributary spares including this bi-tributary card.
