8. Assume that the circuit shown in figure 2-7 is carrying a frequency-
receiving channel outputs of the multiplex terminal, the most probable reason
is that the
a. pad has changed value.
b. attenuator loss is excessive.
d. equalizer is incorrectly adjusted.
9. With a -12 dbm input level from the line and with an attenuator setting of
20 db, the expected level from the circuit to the equipment is
a. -2 dbm.
c. -6 dbm.
b. -4 dbm.
d. -8 dbm.
10. Assume that the TLP has been selected at AMP OUT jack with the level
adjusted to -3 dbm. The relative level of the signal that is applied to the
station equipment is
a. -6 db.
c. -6 dbm0.
b. -9 dbm.
d. -9 dbm0.
11. The technical controller or circuit conditioner may vary the overall gain
of the circuit and thereby determine the output level by adjusting the
12. The maximum undistorted power output of the amplifier is +30 dbm. If this
amplifier is delivering its rated output level, the corresponding output power
delivered to the pad is
a. 1 watt.
b. 2 watts.
NOTE: Use figure 2-1.
c. 1,001 watt.
d. 2 milliwatts.
Assume that you are given a partial transmission level diagram for a long-
distance (LD) trunk (fig. 2-8). The circuit contains three repeaters, and the
received noise level is -50 dbm.
The TLP is designated at the repeater 3
output with a level of +3 dbm. You are to determine the missing values and to
analyze the diagram.
Exercises 13 thru 20 are based on this situation.
