TESTING THE
OUTSIDE LINES
You often need to test an outside line at the network
interface or jack field. This test will verify that the outside
telephone lines are working properly. To perform this test,
you-need a basic rotary dial telephone and a Touch-Tone
telephone, each with a modular cord, or two craft sets.
CAUTION:
Do not use a MERLIN II system voice
terminal for testing. It does not work for this test, and it
can be damaged if you use it for this purpose.
