The NTK557QAE5 is a high-capacity digital cross-connect module used inside Nortel optical transport platforms.
It performs traffic switching and grooming at SONET/SDH levels, handling:
- VT1.5 / VC-12 circuit mapping
- 20G cross-connect fabric operations
- Synchronization (ST3 timing support)
It is not a transceiver or Ethernet card — it is a core transport switching engine inside the chassis.
