Accepted Values

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.
