Description:
The Nortel NTEU11AA is a legacy SDH (Synchronous Digital Hierarchy) transport module used in Nortel optical transport and multiplexing systems. It serves as a lower‑order SDH tributary interface card, providing termination and mapping of SDH tributary signals into the backplane of a modular transport chassis for further aggregation and switching.
