[transmissiontype <transmissiontype>]
where
<profile> = The descriptive name for the profile. Up to 31
characters.
[ramodeds
<manual|rainit|dynamicra|sos>]
[ramodeus
<manual|rainit|dynamicra|sos>]
= 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.
sos: dynamically change the transmission rate. It
also uses emergency rate reduction (SOS) when the
line experiences a noise spike. This helps keep the
connection up as much of the time as possible.
[rausnrmds <up_shift_nrm_ds>]
[rausnrmus <up_shift_nrm_us>]
= 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)
[raustimeds <up_shift_time>]
[raustimeus <up_shift_time>]
= 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.
[radsnrmds <down_shift_nrm_ds>]
[radsnrmus <down_shift_nrm_us>]
= 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.
[radstimeds <down_shift_time>]
[radstimeus <down_shift_time>]
= 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.
[targetsnrmds <target_margin_ds>]
[targetsnrmus <target_margin_us>]
= The downstream (ds) and upstream (us) target SNR
(Signal to Noise Ratio) margin from 0~310 in 0.1dB.
