Alcatel-Lucent 3AL34344AAAC02 legacy SDH/PDH transmission Telecom System Card / Module

The Alcatel-Lucent 3AL34344AAAC02 is a 1×2 Mbit/s interface module used within Alcatel-Lucent’s legacy PDH/SDH transmission shelf families. It provides a single 2 Mbit/s (E1) interface, used to terminate individual low-capacity circuits such as auxiliary data channels, small leased lines, or ancillary signalling links that need to be carried across the same transmission shelf as the main tributary and aggregate traffic. As a compact plug-in module, it fits into the shelf backplane alongside larger multi-port tributary cards and is field-replaceable, allowing engineers to swap it during a maintenance window without disturbing the rest of the shelf’s traffic. Cards of this type remain a routine spare requirement for operators keeping legacy Alcatel-Lucent transmission rings in service in access and metro networks. Tech-Star (UK-based, shipped worldwide) supplies tested Alcatel-Lucent legacy transmission spares including this interface module.
