Description:
The Nortel NTEU12AA is a legacy SDH (Synchronous Digital Hierarchy) transport module used in Nortel optical transport and multiplexer systems. It functions as a lower‑order SDH tributary interface card, providing termination and backplane interfacing for SDH tributary signals inside a modular transport chassis. This allows lower‑order signals to be mapped into the system’s higher‑order transport hierarchy.
