VDSL-Config:Line-Config subprofile The VDSL-Config subprofile
4 - 4 363-217-032R9.9.0
Issue 2, March 2006
ptm-encapsulation
Specifies the packet transfer mode encapsulation to be used for the
frames. Valid values are:
ptm-64-65
—Currently not supported on the VDSL LIM. The
default 64/65-octet encapsulation is used. (IEEE 802.3ah-2004,
Clause 61)
hdlc
—HDLC encapsulation is used. (ITU-T G993.1, Section H.4.1
and ETSI TS 101 270-2, Section 6.2.4.2.1)
line-code
Specifies the DMT line code to be used for training. Valid values are:
auto-select
—In this release, the LIM attempts to train using
VDSL. Currently, automatic selection between VDSL and VDSL2 is
not supported.
vdsl
—The LIM attempts to train using VDSL.
vdsl2
—The LIM attempts to train using VDSL2.
line-latency-down
Currently not supported on the VDSL LIM.
line-latency-up
Specifies the VDSL latency path to be used for upstream data
transport. Valid values are:
none
— Currently not supported on the VDSL LIM.
fast
—(the default) Sets the delay to the lowest possible value.
interleave
—Sets the latency path to
interleave
.
both
—Not used.
Ensure that the line-latency-up and line-latency-down values are
equal before a write profile is performed, otherwise the profile is
rejected as having an invalid setting. This is consistent with adsl2plus
capable packs.
For related settings, see “Bit rate parameters” (p. 4-12) and “The
VDSL-Config:Fast-Path-Config subprofile” (p. 4-16) .
rate-adapt-mode-up
Specifies the rate-adaptive mode for upstream and downstream
training. Valid settings are:
automatic-at-startup
—Specifies that the rate is selected
during the startup process, based on the settings of the
margin-
config
subprofile.
operator-controlled
—Specifies a fixed rate to which the
port trains if the settings in the
margin-config
subprofile are
satisfied.
rate-adapt-mode-
down
Not used—This is controlled by the setting of the
rate-adapt-
mode-up
parameter.
rate-adapt-ratio-
up
Not used.
