Hi, We have something of a problem with some Lucent SDSL equipment right now, and some suggestions from this list might be helpful in getting the issue solved. We're using a DSL-Max and a DSL-Pipeline over some British Telecom supplied copper. It's a single-copper pair, running between two locations. We have set the line speed statically to 272000 at both ends of the link. The next step up seemed to produce an unstable connection. During testing, "autobaud" was either taking too long, or did not appear to work at all. The problem appears to be poor upstream performance from the pipeline. FTP downloads hit high speeds, but uploads slow to a crawl. The same is true for sending mail etc., so it would appear to affect all the traffic on the wire. The pipeline originally used RFC1918 addresses on the ethernet interface, and was running Network address translation. I've not used the pipeline NAT implementation for anything before, so I wasn't sure if this was the cause. I also couldn't gain telnet access to the pipeline when NAT was enabled. I would have hoped that port 23 would be automatically mapped to the external numbered interface address, but that does not appear to be the case. Adding a static mapping so that port 23 points at the pipeline's ethernet interface address does not provide remote access either. I've recently swapped back to using a numbered configuration and have regained remote access to the pipeline, although the main performance issue remains. The code revision on the Max is: 8.0.3, the pipeline is running 7.10.8. Anyone got any ideas before I lose what remains of my sanity?
