This object provides a unique identifier for a specific physical port on a high-speed BERT (Bit Error Rate Test) card installed in a RAD network device, using a naming convention where the first two digits encode the IO slot number plus 10, and remaining digits encode the even-numbered port position. Network technicians use this identifier when referencing specific test points or when correlating test results with physical hardware locations. The index enables systematic port identification across multiple slots and card types.
