FCC Part 68 and UL 1950
In some instances, compliance with UL 1950 does not require a current limiting or
fusing element. Figures 4-26 and 4-27 are line interface protection circuits that meet
FCC Part 68 operationally and the requirements of UL 1950.
FCC Part 68 Only
In some instances, equipment intended for connection to the public network may only
require FCC Part 68 approval. For equipment that only needs to meet FCC Part 68,
Figures 4-26 and 4-27 should be referenced.
