Configuration of the Data Rate

The data transmission rate of a DSL line can be set on both sides of a line. The following
combinations are possible:
– Both sides with a fixed data rate
– One side with a fixed data rate, the other with auto-negotiation
– Both sides with auto-negotiation
2.15.3.1 Both Sides with a fixed Data Rate
Data rate at the local side
192 ... 15000 kbps in steps of 8 kbps
Table 16: DSL connection with fixed data rates on both sides
Data rates of up to 5696 kbps are compliant to ITU-T Standard G.991.2 or G.991.2 Annex F
respectively. Rates beyond this use a proprietary technique.

Data rate at the local side
192, 256, 512, 768, 1024, 1280,

or 5696 kbps

2.15.3.3 Both Sides with Auto-Negotiation
This method is not advised! Even though always the highest achievable rate is selected, it
can be different with every negotiation.
2.15.3.4 Recommendations for Operation
The general recommendation for the operation of DSL lines is to set one side to a fixed
data rate and the other to auto-negotiation. It is recommended to set that station to auto-
