Mapping UI display names to API names and MIB values
Last Updated: July 07, 2026

The following table explains the correlation between values in the ServAssure NXT user interface, the ServAssure NXT public APIs, and DOCSIS MIB values for various FEC statistic types. The CER values are used as an example. CCER and CER+CCER follow the same naming conventions.
