At no time will the short circuit exceed 1 ohm. For equipment with more than one
twisted pair, the short circuit will be applied to all twisted pair simultaneously. To
comply with the short circuit test, the EUT must function normally after the short-circuit
condition has been applied and a fire hazard may not be present.
Intra-Building Lightning and AC Power Fault Test
Not all equipment is intended to be off premise equipment nor is all equipment
intended to interface with the telephone outside plant. For such equipment, the EUT
need only meet the Intra-Building Lightning Surge Test found in Table 4-8 and the
Intra-Building AC Power Fault Test found in Table 4-9.

Note:
The EUT shall not be damaged and shall continue to operate. Because the intensity of
the Intra-Building Tests are much less than those found in Table 4-2 through
Table 4-6, if the EUT only meets the criteria found in Table 4-8 and 4-9, documentation
must be included indicating that the equipment is solely intended for intra-building
(non-exposed wiring) connections.

Note:
For EUT containing secondary voltage limiting and current limiting protectors, tests are
to be performed at the indicated voltage(s) and repeated at a reduced voltage and
current just below the operating threshold of the secondary protectors. This second
level test may be destructive but shall not become a fire, fragmentation or electrical fire
hazard.
