*X denotes the adaptive setting. If this is S then the profile is dynamic, if this F then the profile is fixed. |

*F indicates that interleaving hasn’t been applied and that this is a fast profile. |
**F indicates that interleaving hasn’t been applied and that this is a fast profile. |

*I followed by a number indicates the size of the interleaving delay. The greater the number the greater the interleaving applied. |

*SNR denotes the target Signal to Noise Margin. Where this is a single number, this number indicates the target for both upstream and downstream, where there are two, the first indicates downstream and the second indicates upstream. |

*The lower the number the greater the achievable line rate, the higher the number the higher the number then the lower the achievable line rate. Note: Some fixed profiles omit the SNR property from their name, where this is the case their target margin is 6dB. |
