The CCUD control board supports the following 3 types of ports:


  • Panel ports (on the backplane): CON/ESC (connecting to the 2-in-1 local maintenance and environment monitoring cable), ETH/GE0 (connecting to the network cable), and ALARM (connecting to the environment monitoring cable).

  • Upstream port: GPON/EPON (SFF) port for connecting to optical fibers.

  • Cascade port: Only 1 GE (electrical) cascade port is supported.
