FCC Part 68 and UL 1459/UL 1950
Because equipment that is tested to FCC Part 68 specifications is also generally
tested to UL specifications, it is easiest to look at a solution that meets both FCC and
UL requirements simultaneously.
FCC Part 68 Operational Solution and UL 1459/UL 1950
Figures 4-22 and 4-23 are line interface protection circuits that meet both UL 1459 and
UL1950 power cross requirements and pass FCC Part 68 Type A and Type B lightning
immunity tests operationally.
FCC Part 68 Non-Operational Solution and UL 1459/UL 1950
Although Figures 4-22 and 4-23 provide an operational solution for FCC Part 68, FCC
Part 68 allows telecommunications equipment to pass Type A surges non-
operationally as well. For non-operational FCC Part 68 solutions, the I
PP
rating of the
SIDACtor and the I
2
t rating of the fuse should be coordinated such that both will
withstand the FCC Part 68 Type B surge, but during the Type A surge, the fuse will
open.
Figures 4-24 and 4-25 are line interface protection circuits that meet UL power cross
requirements and pass FCC Part 68 lightning immunity tests non-operationally.
