Is a good link on Serial Line Troubleshooting. It also covers extended pings
and several data patterns

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
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
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).

Quick snippit for those that may not have a router handy:
router#ping
Protocol [ip]:
Target IP address: 192.168.45.253
Repeat count [5]: 1000
Datagram size [100]: 1400
Timeout in seconds [2]:
Extended commands [n]: y
Source address or interface: ethernet1
Type of service [0]:
Set DF bit in IP
I've done that before once or twice... the type of thing they are talking
about is to send a 0x out to test all 1s and the like.
