Function Implementation

This section describes the implementation principle and signal flow of the PID service.

• Implementation Principle
  The PID feature is implemented by using the ELQX and PTQX cards or the ENQ2 and NPO2 cards.
• ENQ2 Board Service Configuration
  On the U2000 Web LCT, the logical ports of the board are provided.
• NPO2 Board Service Configuration
  On the U2000 Web LCT, each optical interface on the NPO2 board has a serial number, and the logical ports of the board are provided.
• NPO2E Board Service Configuration
  On the U2000 Web LCT, each optical interface on the NPO2E board has a serial number, and the logical ports of the board are provided.
