Alcatel-Lucent 3AL34711AB N+1 switching module, 34/140 Mbit/s, for Alcatel-Lucent legacy PDH/SDH transmission shelves.

The Alcatel-Lucent 3AL34711AB is an N+1 switching module supporting both 34 Mbit/s and 140 Mbit/s traffic, built for Alcatel-Lucent’s legacy PDH/SDH transmission shelves. N+1 switching protects a group of working tributary or aggregate cards with a single shared protection unit, so that if one working card fails, the switching module automatically routes its traffic onto the protection path, keeping service running while the faulty card is replaced. This kind of resilience is standard practice on transmission shelves carrying revenue traffic, and the 34/140 Mbit/s dual-rate capability lets a single switching module protect ports operating at either rate within the same shelf group. As a plug-in module, the 3AL34711AB is field-replaceable, letting engineers restore or expand N+1 protection on an in-service shelf without a wider outage. Tech-Star (UK-based, shipped worldwide) supplies tested Alcatel-Lucent legacy transmission spares including this N+1 switching module. Contact us to confirm shelf compatibility before ordering.
