Chapter 32 profile Commands
= The descriptive name for the profile. Up to 31
characters.
= The downstream (ds) and upstream (us) rate
adaption settings.
manual fixes the transmit rate as the minimum net
data rate and disable transmission rate adjustment.
If the attainable speeds cannot match configured
speeds, then the VDSL link may go down or link
communications may be sporadic due to line errors
and consequent retransmissions.
rainit uses the transmit rate initially negotiated
between CO and CPE devices. It ranges from the
configured minimum to the maximum net data rate
based on the initial line condition.
dynamicra dynamically changes the
transmission rate negotiated between the system
and CPE devices during initialization as well as
during SHOWTIME status.
= The downstream (ds) and upstream (us) up-shift
SNR margin threshold. Enter the number of
decibels (in 0.1 dB). When the line's signal-to-noise
margin goes above this, the system attempts to
use a higher transmission rate.
(<target_margin_ds>~310 in 0.1 dB
measurements)
= The downstream (ds) and upstream (us) rate
adaptive up-shift time. Enter the number of
seconds (0~16383) to wait before using a higher
transmission rate when the line's SNR margin is
over the up-shift SNR margin threshold.
= The downstream (ds) and upstream (us) rate
adaptive down-shift SNR margin threshold. Enter
the number of decibels (0~<target_margin_ds> in
0.1dB). When the line's signal-to-noise margin
goes below this number, the system attempts to
use a lower transmission rate.
= The downstream (ds) and upstream (us) rate
adaptive down-shift time. Enter the number of
seconds (0~16383) to wait before using a lower
transmission rate when the line's SNR margin is
less the down-shift SNR margin threshold.
= The downstream (ds) and upstream (us) target
SNR (Signal to Noise Ratio) margin from 0~310 in
0.1dB.
