Notes:
When performing longitudinal tests, the test generator will have a dual output.
Refer to Table 4.2 for switch positions for each test condition.
Note: Other outside plant leads associated with the unit should be grounded during the test and the test repeated with these leads
terminated as in service. Leads that do not connect to outside plant should be terminated as appropriate for the operating
mode(s) of the unit.
