Configure a VDSL2 line profile.
1.
Run the vdsl service-profile quickadd command to quickly add a VDSL2 service
profile, or run the vdsl service-profile add command to interactively add a VDSL2
service profile.
A VDSL2 service profile contains the most common parameters of a VDSL2 line. In
general, only the configuration of a VDSL2 service profile is required. In the case of
other profiles, adopt the default profiles. Main parameters:
– path-mode: Indicates the path mode. There are two VDSL2 path modes: ATM
mode and PTM mode. To set the ATM mode as the VDSL2 path mode, select
atm. To set the PTM mode as the VDSL2 path mode, select ptm.
– rate: Indicates the line rate. During line activation, a proper rate between the preset
maximum rate and minimum rate is determined through automatic negotiation
according to the line condition and the profile configuration. The user rate can be
restricted by this rate or the rate set in the traffic profile bound to the user. When
both rates function, the lower rate is selected as the user rate.
2.
Run the vdsl delay-inp-profile quickadd command to quickly add a VDSL2 delay
INP profile, or run the vdsl delay-inp-profile add command to interactively add a
VDSL2 delay INP profile. Main parameters:
– bearer1-inp: The INP is a parameter that describes the line capability of resisting
impulse interference. The INP affects the port rate. If the INP is 1, it indicates that
the current channel can resist the impulse noise in 1 DMT character length. The
interleave delay is related to the INP. In the fast mode, the INP is meaningless.
– bearer1-interleaved-delay: A zero interleave delay corresponds to the fast mode.
In the fast mode, the interleave delay is short, but the error correction capability is
weak. A non-zero interleave delay corresponds to the interleave mode. The longer
the interleave delay, the greater the interleave depth. In the interleave mode, the
greater the interleave depth, the stronger the error correction capability, but the
longer the delay.
3.
Run the vdsl noise-margin-profile quickadd command to quickly add a VDSL2 SNR
margin profile, or run the vdsl noise-margin-profile add command to interactively
add a VDSL2 SNR margin profile. Main parameter:
snr-margin: Indicates the SNR margin. It refers to the remaining space for carrying
noise, except the space for carrying signals. In general, the SNR margin of the
minimum tone is used as the SNR margin of the entire VDSL2 connection.
4.
Run the vdsl spectrum-profile quickadd command to quickly add a VDSL2
spectrum profile, or run the vdsl spectrum-profile add command to interactively add
a VDSL2 spectrum profile. Main parameter:
transmode: Indicates the line transmission mode. By default, the system supports all
transmission modes. The default setting can be used. Then, the system automatically
adapts to the transmission mode of the peer end.
5.
Run the vdsl upbo-profile quickadd command to quickly add a VDSL2 UPBO
profile, or run the vdsl upbo-profile add command to interactively add a VDSL2
UPBO profile.
6.
Run the vdsl dpbo-profile quickadd command to quickly add a VDSL2 DPBO
profile, or run the vdsl dpbo-profile add command to interactively add a VDSL2
DPBO profile.
