For E3 mode, ITU-T G.703 Recommendation specifies that the receiver be able to recover error free clock and
data in the presence of a sinusoidal interfering tone signal. For DS3 and STS-1 modes, the same
recommendation is being used. Figure 10 shows the configuration to test the interference margin for DS3/
STS1. Figure 11 shows the set up for E3.
