sys-option
Bit[0]: NTR_DISABLE
Bit[1]: ALW_MARGIN_ADJUST.
1: the SNR margin for the optional band is reduced by up to 2.5
dB, but never below a minimum of 4 dB.
Bit[2]: SUPPORT_INI
Bit[4]: TLAN Enable
Bit[5]: PBO Weak mode Enable (Applicable only when PBO
Bit[3]=0.
Bit[6]: ADSL_SAFE_MODE Enable
Bit[7]: TLAN_SAFE_MODE Enable (Applicable only when TLAN
Enable Bit[4] is set. If TLAN_SAFE_MODE not set, line will
attempt to retrain at higher rates, but less stable line)

pbo-k1_1
K1 and K2 parameters allow the user more flexibility in using
Upstream Power Back-Off (UPBO) on CPE modem. Changing
K1 and K2 values will affect the CPE TX PSD. Refer to VDSL
standards for exact relation between K1, K2 parameters and TX
PSD. There is an individual set of K1/K2 parameters associated
with each upstream band in the PSD: Upstream Band 0 or
Optional band, Upstream band 1, Upstream band 2 and
Upstream Band 3. Setting all K2 parameters to 0 and all K1 to a
high power level(ie low number) will essentially disable UPBO.
