CHAPTER 4: Test Procedures
10. Put the Test Set in the CONTINUITY Test Mode.
11. a. If the Green Test Status light goes on, there is a physical connection
between the terminal and the NT1.
b. If the Red Test Status light goes on, there is no continuity on the
receive pair between the terminal and the NT1. You should check
the loop for opens. There’s no need for any further testing.
12. The problem may be that the signal received at the NT1 is too low.
To check this, put the Test Set back in the NORMAL mode by pushing
the LINE button.
13. Put the Test Set in the LEVEL test mode.
14. a. If the Green Test Status light goes on, the terminal is receiving the
proper level. The problem may be that either the switch or the NT1
isn’t working.
b. If the Red Test Status light goes on, the signal level at the terminal
is too low. Check the loop length.
