IES-1248-51/51A/53 User’s Guide
451
This command sets the upstream (us) and downstream (ds) impulse noise protection minimum
setting on the specified ADSL port(s). Sudden spikes in the line’s noise level (impulse noise)
can cause errors and result in lost packets. Set the impulse noise protection minimum to have a
buffer to protect the ADSL physical layer connection against impulse noise. This buffering
causes a delay that reduces transfer speeds. It is recommended that you use a non-zero setting
for real time traffic that has no error correction (like videoconferencing).
The following example sets the impulse noise protection minimum to 1 DMT symbols for
upstream and 0.5 DMT symbols for downstream for ADSL port 5.
