Nortel NTEU16QA STM2E quad tributary card for the Optical Metro 4000/4200 SDH transmission platform.
The Nortel NTEU16QA is an STM2E quad tributary card for the Optical Metro 4000/4200 platform, Nortel’s SDH transmission system for multiservice access, metro edge and regional networks.
The card provides four independent STM-1 electrical tributary interfaces on a single plug-in module, letting an Optical Metro 4000/4200 shelf add several lower-rate electrical tributaries in one slot rather than needing separate single-port cards. It sits in the same tributary card family as the single-port NTEU11AA (2Mbit/s), NTEU13AA (STM-1E/140Mbit/s) and NTEU20AA (STM-4) cards documented for this shelf.
This card belongs to the Nortel Optical Metro SDH transmission estate. Tech-Star (UK-based, shipped worldwide) checks every card before it ships. Get in touch to confirm compatibility with your Optical Metro 4000/4200 system.
