ALCATEL 3AL97078AD -Lucent 1642 EM / 1642 EMUX Telecom System Card / Module

The Alcatel 3AL97078AD is catalogued as an SE1B28 board for the Alcatel-Lucent 1642 EM / 1642 EMUX edge multiplexer platform. The 1642 EM is a compact SDH/MSTP multiservice provisioning system within Alcatel-Lucent’s Optical Multi-Service Node (OMSN) family, combining legacy TDM tributary interfaces with Ethernet access in a single shelf for metro and access network deployments. Boards in the SE1B28 series provide E1-related tributary and switching functionality within that shelf, plugging into the platform’s card cage alongside its controller, power supply and Ethernet interface boards. As with other 1642 EM plug-in modules, the SE1B28 is a field-replaceable unit intended for engineers maintaining, expanding or repairing existing 1642 EM/EMUX installations, and is issued by Alcatel-Lucent across a series of hardware revisions identified by the trailing suffix letter, of which this is the ‘AD’ revision. Buyers should confirm exact revision compatibility against their existing shelf configuration before ordering.
