Parameter

Description

Profile Index

Parameter

Description

Transmission mode

G992.1 and T1.413 are protocols for full rate ADSL. The maximum downstream rate is 8 Mbit/s.

G992.2 (G.Lite) is the protocol for ADSL without a splitter. The maximum downstream rate is 1.5 Mbit/s.

G992.3 is the protocol for ADSL2. The maximum downstream rate is 12 Mbit/s.

G992.4 is the G.Lite protocol for ADSL2 without a splitter.

G992.5 is the protocol for ADSL2+. The maximum downstream rate is 24 Mbit/s.

G993.2 is the protocol for VDSL2 in the DMT mode. The maximum frequency is 30 MHz, and the maximum upstream and downstream rates are both 100 Mbit/s.

When configuring a profile, select at least one transmission mode. It is recommended to select all. In the process of adding, deleting or modifying the transmission mode, you can select one or multiple options.

Bit swap downstream/upstream

Indicates whether the bit swap function is enabled in downstream/upstream.

The form of transmit rate adaptation downstream/upstream

In fixed mode, the line must be activated at the specified upstream/downstream activation rate. When a VDSL2 line profile is bound to a VDSL2 line template, if the transmission rates are not the same as the minimum and maximum rates in the corresponding direction in the VDSL2 channel profile, the system prompts that the maximum and minimum downstream rates of the channel must be the same and the line profile cannot be bound.

In adaptAtStartup mode, after the line is activated, the activation rate is within the minimum and the maximum activation rates configured in the VDSL2 channel profile.

In adaptAtRuntime mode, the line rate during online activation varies between the maximum and minimum rates and line retraining is not required.

In SOS auto-adaptive mode, during online activation of the line, the rate changes between the minimum rate and maximum rate. Line retraining is not required. Compared with the adaptAtRuntime, the SOS function takes effect when the actual rate is smaller than the minimum rate.

Target SNR margin downstream

Minimum SNR margin downstream

Maximum SNR margin downstream

Target SNR margin upstream

Minimum SNR margin upstream

Maximum SNR margin upstream

Indicates the noise margin. Noise margin refers to the margin reserved for sub-channels when you allocate bits for them. When the environment change descends the sub-channel noise, the transmission quality can be ensured only if the descending range does not exceed the noise margin.

Target noise margin in the upstream/downstream direction: The target noise margin is the required noise margin to complement training in the case of lower or the same bit error rate.

Minimum noise margin in the upstream/downstream direction: If the line condition deteriorates and the line noise margin becomes lower than the minimum noise margin, the system will add the transmitting power to increase the line signal to noise ratio (SNR) and then to meet requirements of the current line rate.

Maximum noise margin in the upstream/downstream: If the line conditions are quite well and the line noise margin exceeds the maximum, the system will reduce the transmitting power to limit the line SNR.

Each range consists of the start tone and the end tone. The frequency bandwidth for each tone is 4.3125 kHz. Notch the corresponding frequency ranges, that is, do not use these frequency ranges. When setting the parameter, pay attention to the following points:

A maximum of 16 frequency ranges can be set, such as 50,100-200, 300-350. The tone index ranges from 0 to 6956. Input format: sub-carrier index (the start sub-carrier index-the end sub-carrier index). Up to 16 ranges can be set, such as 50, 100-200,300-350.

Generally, set a small frequency range to mask radio interference. If the range is too large, lines may no be activated.

<defmode>

On a line, there must be a set of default power frequency spectrum parameters mapping "defmode" parameter.

Not all transmission modes need to be configured with PSD parameters. To activate a line in a specified transmission mode, preferentially query and use the power spectrum parameter corresponding to this transmission mode. If this parameter cannot be found, use the default power spectrum parameter, namely, defmode, to activate the line.

G.993.2 profile

G.993.2 profile affects the range of total upstream/downstream nominal transmission powers. VDSL2 has eight defined profiles (8a, 8b, 8c, 8d, 12a, 12b, 17a and 30a) to meet the requirements of different application scenarios.

If the xTUs at both ends do not support the retransmission function or the retransmission function is not selected in the current direction, the line initialization fails. Then, the central office (CO) and the customer premises equipment (CPE) perform protocol rollback based on the configured transmission mode.

3: RTX_TESTMODE: indicates that the G.998.4 retransmission function is forcibly to use in test mode. If the xTUs at both ends do not support the retransmission function or the retransmission function is not selected in the current direction, the line initialization fails. Then, the CO and the CPE perform protocol rollback based on the configured transmission mode.

Parameter

Description

Profile index

Indicates the ID of a VDSL2 channel profile.

Name

Indicates the name of a VDSL2 channel profile.

MinDw Rate

Indicates the minimum activation rate in the downstream direction.

MaxDw Rate

Indicates the maximum activation rate in the downstream direction.

MinUp Rate

Indicates the minimum activation rate in the upstream direction.

MaxUp Rate

Indicates the maximum activation rate in the upstream direction.

Data path mode

Indicates the data path mode. There are two types of modes: asynchronous transfer mode (ATM) and packet transfer mode (PTM). In general, only aVDSL2 line supports the PTM mode. By default, the system supports both of them. You can select the mode for a board based on the actual line conditions.

Ref Times

Indicates the count that a VDSL2 channel profile is referenced by the VDSL2 channel template.

Parameter

Description

Profile index

Indicates the ID of a VDSL2 channel profile.

Name

Indicates the name of a VDSL2 channel profile.

Data path mode

Indicates the data path mode. There are two types of modes: ATM and PTM. In general, only a VDSL2 line supports the PTM mode. By default, the system supports both the ATM and PTM modes. You can select the mode for a board based on actual line conditions.

Minimum impulse noise protection downstream/upstream

INP defines how many discrete multi-tone (DMT) consecutive symbols can be protected. That is, how many consecutive error DMT symbols in a specified byte can be rectified in the case of deinterleaving. The upstream and downstream INP is set separately. The options for symbol length are: no protection, a half symbol, a single symbol, two symbols, ..., sixteen symbols.

INP is defined as the protected consecutive DMT symbols but not the impulse noise duration. The impulse noise duration is related to DMS symbol ratio.

There are multiple VDSL2 profiles. The DMT bit rate of 30a profile is 8.625 kbit/s and that of other profiles is 4.3125 kbit/s.

For example, if INP is 16, the consecutive impulse noise of 16 x 1/4.3125 = 3.7 ms in the 8a profile and the consecutive impulse noise of 16 x 1/8.625 = 1.85 ms in the 30a profile can be protected.

Maximum interleaving delay downstream/upstream

Indicates the downstream/upstream interleave delay. The interleave delay refers to the delay caused by interleave processing. Interleaved delay is related to interleaved depth, bit length and line rate.

By default, VDSL2 works in interleaved mode.

Minimum transmit rate downstream(Kbps)

Minimum reserved transmit rate downstream(Kbps)

Maximum transmit rate downstream(Kbps)

Minimum transmit rate upstream(Kbps)

Minimum reserved transmit rate upstream(Kbps)

Minimum data rate in low power state(Kbps)

The ratio between L2 minimum rate and L0 rate

Maximum data rate in low power state(Kbps)

Indicates the transmission rate. Rate parameters include the maximum/minimum upstream/downstream activation rate parameters.

The actual line activation rate is self adapted in the set rate range. Finally a rate which meets the activation requirements (with bit error rate smaller than 10 -7 and noise margin close to the target SNR margin) is used to activate lines.

When the adaptation mode for transmission rate in a channel profile is fix, the maximum activation rate must be the same as the minimum in the same direction. When the rate adaptation mode is not fix, the maximum rate must be larger than the minimum rate.

The ratio of low power rate to the normal rate is 0 by default, indicating that min-rate-lowpower restrictions are used. Otherwise, the minimum rate in low power is determined by L0 multiplied by the ratio.

Minimum reserved transmit rate upstream/downstream

Indicates the upstream/downstream minimum reserved rate.

The minimum reserved rate must be larger than or equal to the minimum rate and must be smaller than or equal to the maximum rate. When the adaptation mode of the transmission rate is defined as the self-adaptation mode in the line profile, the transmission rate is adapted based on this value.

Rate threshold downshift upstream/downstream

Indicates the downshift adaptation threshold of the upstream/downstream rate.

When the adaptation mode of the transmission rate is defined as the self-adaptation mode in the line profile, the system generates an alarm if the downshift adapted value of the upstream/downstream rate exceeds this threshold.

Rate threshold upshift upstream/downstream

Indicates the upshift adaptation threshold of the upstream/downstream rate.

When the adaptation mode of the transmission rate is defined as the self-adaptation mode in the line profile, the system generates an alarm if the upshift adapted value of the upstream/downstream rate exceeds this threshold.

PHY-R control in upstream/downstream

Indicates the upstream/downstream retransmission function at the physical layer.

Erasure decoding switch

Cancels decoding function.

Minimum SOS bit rate upstream/downstream

Indicates the minimum upstream/downstream SOS bit rate.

Minimum expected throughput upstream/downstream

Indicates the minimum expected throughput rate in upstream/downstream.

Maximum expected throughput upstream/downstream

Indicates the maximum expected throughput rate in upstream/downstream.

Maximum net data rate upstream/downstream

Indicates the maximum net data rate in upstream/downstream direction.

Minimum delay upstream/downstream

Indicates the minimum delay in upstream/downstream retransmission.

Maximum delay upstream/downstream

Indicates the maximum delay in upstream/downstream retransmission.

Minimum impulse noise protection against single high impulse noise event upstream/downstream

Indicates the minimum INP against a single high impulse noise event in upstream/downstream, with a sub-carrier spacing 4.3125 kHz.

Minimum impulse noise protection against single high impulse noise event transported over DMT symbols with a subcarrier spacing of 8.625kHz upstream/downstream

Indicates the minimum INP against a single high impulse noise event in upstream/downstream, with a sub-carrier spacing 8.625 kHz.

Single high impulse noise event ratio upstream/downstream

Indicates the single high impulse noise event ratio in upstream/downstream. The condition for generating a single high impulse noise event is unknown. Therefore, this parameter is set based on experience.

Minimum impulse noise protection against repetitive electrical impulse noise upstream/downstream

Indicates the minimum INP against repetitive electrical impulse noise in upstream/downstream, with a sub-carrier spacing 4.3125 kHz.

Minimum impulse noise protection against repetitive electrical impulse noise transported over DMT symbols with a subcarrier spacing of 8.625kHz upstream/downstream

Indicates the minimum INP against repetitive electrical impulse noise in upstream/downstream, with a sub-carrier spacing 8.625 kHz.

Repetitive electrical impulse noise inter-arrival time upstream/downstream 0-100Hz 1-120Hz

Indicates the interval of receiving repetitive electrical impulse noise in upstream/downstream. There are two types of interval: 0 and 1. 0 indicates the interval of receiving the repetitive electrical impulse noise with frequency 100 Hz. 1 indicates the interval of receiving the repetitive electrical impulse noise with frequency 120 Hz.

Channel initialization policy selection

Indicates the channel initialization policy. It includes three modes:

0: indicates that the rate is prioritized.

1: indicates that the impulse noise protection (INP) is prioritized.

2: indicates that the signal to noise ratio (SNR) is set to larger when the rate meets the requirement.

Maximum delay variation (0.1ms)

Indicates the variation range of the maximum delay.

Numeral type. Range:1-255.

Unit: 0.1ms.

Default value: 255.

Max delay octet split parameter (percents)

1-4, 96-99, 255: The MAXDELAYOCTET-split is configured by the vendor.

0: This value is valid only when the downstream maximum interleave delay is S1 (fast channel) and the retransmission function is disabled in the downstream direction.

100: This value is valid only when the upstream maximum interleave delay is S1 (fast channel) and the retransmission function is disabled in the upstream direction.

Unit: percentage.

Default value: 255.

Only Two Cosmic Doomsdays Are Certain

The sardonic proverb "nothing is certain but death and taxes," can now be recast for the cosmos.

Last week's announcement of the inevitable collision of the Andromeda galaxy with the Milky Way is one of only two apocalyptic astronomical predictions that we can be absolutely certain of. The other is the death of our sun. Purely deterministic processes drive both.
