An interfering signal (2
rate) is added to the wanted signal. The combined signal is passed through 0 to 900ft of coaxial cable and presented to the LIU.
This spec indicates the lowest signal-to-noise ratio that results in a bit error ratio <10
Not tested during production test.
Measured on the line side (i.e., the BNC connector side) of the 1:2 receive transformer

With respect to nominal 800mVpk signal for DS3/STS-1 and nominal 1000mVpk signal for E3.
Measured on the line side (i.e., the BNC connector side) of the 2:1 transmit transformer
Measured with jitter-free clock applied to TCLK and a bandpass jitter filter with 10Hz and 800kHz cutoff frequencies. Not tested
