Thanks a lot for confirming!
Since the DE is mentioned in the DocCD saying "Frame Relay DE group
functionality is supported on process-switched packets only." That brings up
the question whether Cisco is really aware of its misconception that's
creating for most people! The DocCD says something but in reality it's
something different! So which way the proctor in the lab would go when
marking the exam?!
Best Regards,
Digital
