==Understanding the Profile Names==
===Annex A===
Annex A line profiles are of the form:
XYYY_SNR_DDD_UUU_Protocol
*UUU indicates the maximum upload speed.
*Protocol indicates if the profile is tied to a specific ADSL protocol. Where this is negated, the profile will negotiate with the CPE starting at ADSL2+ and working down to G.DMT.
===Annex M line profiles===
Annex M line profiles are of the form:
MXYYY_SNR_DDD_UUU:MInpN
Where:
*M denotes that this is an Annex M profile.
*X denotes the adaption setting.
*(S) Dynamic: This is where a maximum downstream speed is set but the line may not support that speed so the highest supportable speed is negotiated.
*(F) Static: This is where a maximum downstream speed is set and the line will be fixed at that specified speed.
*YYY denotes the Interleaving settings.
*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 Margin. Where this is a single number, this number indicates the target for upstream and downstream, where there are two, the first indicates downstream and the second indicates upstream Note: Some fixed profiles omit the SNR property from their name, where this is the case their target margin is 6db.
*DDD indicates the maximum download speed.
*UUU indicates the maximum upload speed.
*MInpN denotes the Impulse Noise Protection values. Where this is set to 0 there is in none, else the values are that for Downstream followed by upstream, H denotes 1⁄2
a tone.
