If you have a DSL port that is experiencing many Uncorrected Errors, you can make several configuration changes on the T5 switch to help alleviate or limit them. Use one or all of the following configuration options to help reduce or remove CRC errors:
- Enable Interleaver - Interleaver is another layer of error correction that can be configured to help reduce CRCs. It adds a very small amount of latency to the DSL, but should not impact most applications.
- Lower the configured maximum DSL speed - lowering the speed will allow the DSL line to have more margin and makes the line more resilient to the effects of induced noise.
- Raise the link margin - raising the link margin basically accomplishes the same thing as lowering the maximum link speed.
All of these options can be configured on the T5 GUI. Go to Configure -> DSL screen.
