2) Determine the proper impedance for each 
trunk and then strap its NCOU circuit for either 
600- or 900-ohm operation. Install the short- 
ing bar across the center pin and the outer pin 
labeled either 600 or 900 at each strapping 
location (Figure 4-19). Each circuits strap- 
ping location is shown as follows:

7) In some installations, particularly those near 
the serving Central Office, noise may be intro- 
duced over the CO trunk that will appear as 
sidetone at the telephone. In such situations, 
a 2dB pad can be inserted into the line, for 
either incoming voice or outgoing voice, to 
reduce the sidetone. Strapping options for the 
2dB pad are shown below. 
8) Install the NDTU in the TOO slot in the main
