access users, set the target SNR margin to 3; for users with higher priorities, set the
target SNR margin to 5.
NOTE
The H832SHLH board supports G.SHDSL.BIS and the maximum rate can be 5696 kbit/s.
l
Configure an SHDSL alarm profile.
Run the
shdsl alarm-profile quickadd
command to quickly add an SHDSL alarm profile,
or run the
shdsl line-profile add
command to interactively add an SHDSL alarm profile.
----End
Example
To add SHDSL line profile 3 with the line rate of 4096 kbit/s, which is used to activate the 4-
wire SHDSL port, do as follows:
huawei(config)#
shdsl line-profile quickadd 3 line four-wire rate 4096
Assume that the loop attenuation threshold is 10 dB, SNR margin is 0 dB, ES threshold is 100s,
SES threshold is 100s, CRC abnormality duration threshold is 10000, LOSWS threshold is 100s,
UAS threshold is 100s. To quickly add SHDSL line alarm profile 3 with these parameters, do
as follows:
huawei(config-if-shl-0/3)#
shdsl alarm-profile quickadd 3 loop-attenuation 10 snr-
margin
0 es 100 ses 100 crc-anomaly 10000 losws 100 uas 100
3.7.3 Configuring the VDSL2 Profile
This topic describes how to configure the VDSL2 line profile and alarm profile.
Context
The MA5616 supports two VDSL2 modes, normal mode and TI mode, which are selected by
running a command. By default, the system supports the normal VDSL2 mode.
In the two modes, the alarm profiles are the same but the line profiles are different:
l
Normal mode: It is the mode for VDSL2 general profiles. VDSL2 general profiles are
classified into the VDSL2 line profile, VDSL2 channel profile, and VDSL2 line template.
l
TI mode: In TI mode, the parameters in the VDSL2 profile are re-organized. Specifically,
the parameters are classified by type and frequency used. In TI mode, VDSL2 profiles are
classified into six types: VDSL2 service profile, VDSL2 spectrum profile, VDSL2 UPBO
profile, VDSL2 DPBO profile, VDSL2 SNR margin profile, and VDSL2 delay INP profile.
In the two modes, the line parameters are the same. You can select a mode according to the
configuration requirement.
3.7.3.1 Configuring the VDSL2 Profile (Normal Mode)
This topic describes how to configure the VDSL2 line profile and alarm profile in the normal
mode.
Prerequisites
Run the switch vdsl mode to tr129 command to switch to the VDSL2 mode normal.
