Re: Extended Ping and data pattern
It is used to stress test WAN connections. I don't remember the details, but I think the theory is certain telco equipment fail and detect certain data patterns incoorrectly. WAN lines can work sometimes for certain data/apps but for some others they don't. It's weird, but I used to troubleshoot WAN lines and it happens enough. Run data patterns like 0x or 0x or a variety of others. If any one of them fail, call the telco and tell them. --- John lay <[EMAIL PROTECTED]> wrote: > Guys, > > While studying the CIT.

Re: Extended Ping and data pattern
I've used 0x pattern with mtu 1500 to find out if the line cant handle an all zero's. If this test fails it usually means a telco line coding mismatch (ami versus b8zs) I've also used the 0x4040 pattern ( any pattern with seven consecutive zeros eg 0x1010, 0x8080 etc) to find marginal telco circuits. I'm not sure why this flushes out telco problems, but it has worked for me in the past. I've used 0x in some of my tests but this doesn't usually have any failures. I think that this would show if a telco repeater was failing. I hope this helps. I've had some experience troubleshooting digital circuits for a global telco so that's why I run through these tests.

Re: Extended Ping and data pattern
You can also use 0x and 0x4040 patterns.

Re: Extended Ping and data pattern
I would like to know whether somebody really found a problem in the CSU/DSU or the cables by varying the pattern in the extened ping? What is the relation between the patterns and problems? Say if I got CRCs when using 0x, what does this mean? CSU/DSU or cable?

RE: Extended Ping and data pattern
Hmmm, never knew that... but I always use the extended ping to test our connectiveity through a VPN to company remote locations. 5 pings isn't enough to determine if the connection is reliable, at least 50 better yet 100 if you are separated by a large geographically distance (as we are).

Extended Ping and data pattern
Guys, While studying the CIT. I read that using the extended ping you can change the data pattern (0xABCD the default) to debug data sensitivity problems on CSU/DSUs or to detect cable-related problems such as crosstalk. I don't understand that, did anybody tried it. Thanks a lot ___ Tired of slow Internet?
