Table 4-2 First Level Lightning Surge Test
Notes:
1. Primary protectors are removed for all tests.
2. 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.
3. Test 1 and 2 can be replaced with test 3 or vice-versa.
4. This test is to be performed on up to 12 Tip and Ring pairs simultaneously.
Second Level Lightning Surge Test
The Second Level Lightning Surge Test (Table 4-3) does not require the EUT to pass
operationally, but GR 1089 does require that the EUT not become a fire,
fragmentation, or electrical safety hazard. This is referred to as passing
non-
operationally
.

Notes:
1. Primary protectors are removed
2. 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.
AC Power Fault Tests
Because power companies and operating companies often share telephone poles,
trenches, and the like, network equipment is often subjected to the voltages seen on
power lines. If direct contact between the telephone line and the primary power line
occurs, the operating companies network equipment may see as much as 600V
RMS
for 5 seconds, by which time the power companies power system should clear itself. If
direct contact occurs with the secondary power line, voltages will be limited to
277V
RMS
, but these voltages may be seen indefinitely because the resultant current
may be within the operating range of the power system and the power system will not
reset itself.
