[dynamicd

Configures SOS emergency rate reduction on the
VDSL port(s).
sosminrate : minimum bearer rate that must be
gauranteed after an SOS request, 0~100032 kbps.
sostime : duration of the SOS time window, 64 ~
16320 ms.
soscrc: minimum number of normalized CRC
anomalies, 0 ~ 65535 in units of 0.02 that must
occur during the time window to trigger SOS.
sosntone: minimum percentage of degraded tones
that must also occur throughout the time window
to trigger SOS, 0 ~ 100.
sosmax: maximum allowed number of successful
SOS procedures within 120 seconds before
triggering a full re-initialization, 0 ~ 15.
rocsnrm: extra signal-to-noise ratio margin to add
for the ROC (Robust Overhead Channel), 0 ~ 310
in 0.1 dB units.
rocmininp: required INP_no_erasure value
(impulse noise protection) for the ROC, 0 ~ 16.
rocenable: turn the use of the ROC on or off.
dynamicd: turn dynamic interleave depth
adjustment on or off.
8
tls disable <slot-port>
Disables Transparent LAN Service (TLS). The
system does not insert additional VLAN tags to
packets.
8
enable <slot-port>
Turns on Transparent LAN Service (TLS) to insert
additional VLAN tags to packets.
8
set <slot-port>
<svid> <spriority>
Sets/changes TLS settings on the VDSL port(s).
svid: The service provider VLAN ID.
spriority: The service provider IEEE 802.1p
priority setting.
8
tpstctype <slot-port> adsl
atm|ptm
Sets to use ATM or PTM encapsulation in the
Transport Protocol Specific Transmission
Convergence (TPS-TC) sub-layer for ADSL
connections. The CPE must also support the same
setting you use. So you can use PTM if the CPE
supports it, otherwise you must use ATM.
8
upbo enable
Enables the Upstream Power Back Off (UPBO)
feature.
8
disable
Disables the UPBO feature. 8
param <slot-port>
<a0> <b0> <a1> <b1>
[<a2> <b2>
ai: UPBO Ai parameter for USi (-20725~-10240 in
1/256 dBm/Hz).
bi: UPBO Bi parameter for USi (-10485~0 in 1/256
dBm/Hz).
8
show <slot-port>
Displays UPBO settings for the specified port. 8
