Not entirely sure, but it's likely that we are pushing the workable limits. Maybe the copper run is between three and four kilometers? Now we're not using NAT, I've got access to the pipeline back again. I can immediately see that there are errors on the Wan interface: WAN Stat Rx Pkt: 2292 Tx Pkt: 2796 CRC: 586v I have swapped the data rate from 272000 to the lowest setting, 144000 baud. The same CRC errors occur. Telnet to the pipeline feels laggy, with loads of delay. I think there are plenty of packets being re-sent. Just to totally contradict everything, I can ping the pipeline and get no loss with a reasonably consistent 100ms time, even with large ping packets. The pipeline says Line quality is "4db Good". I have been considering trying BERT tests, but find myself wondering if this will provide any useful information? STAC compression is currently enabled, which I am about to turn off... As I said before, downstream traffic seems fast and reliable. I can't think why there should be any assymetry. If the line is noisy, it should affect traffic both ways? - Matt ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request at bungi.com To get FAQ'd: <http://www.nealis.net/ascend/faq>
