The SELT quiet line noise provides the quiet line noise PSD as measured by the SELT-PMD
function (see clause A.1.1.2) for each sub-carrier frequency i * SELTQLN_G * Df where i ranges
from 0 to NSC-1, Df = 4.3125 kHz, and (NSC-1) * SELTQLN_G * Df is the highest frequency
supported by the SELT-PMD functionality. SELTQLN_G has two valid values: 1 and 2, indicating
whether the measurements were performed using a tone spacing of 4.3125 kHz or of 8.625 kHz. If
the SELT quiet line noise is being reported over a frequency range of 17.664 MHz or lower,
SELTQLN_G shall be set to 1. If the SELT quiet line noise is being reported over a frequency
range that is greater than 17.664 MHz, SELTQLN_G shall be set to 2.
SELT quiet line noise SELTQLN(i * SELTQLN_G * Df) shall be represented as an 8-bit unsigned
integer n(i), where i is the subcarrier index i = 0 to NSC-1. The value of
SELTQLN(i * SELTQLN_G * Df) shall be defined as SELTQLN(i * SELTQLN_G * Df ) =
-23 - (n(i)/2) dBm/Hz. This data format supports a SELTQLN(f) granularity of 0.5 dB and an
SELTQLN(f) dynamic range of -150 to -23 dBm/Hz.
