ShowtimeRetrain Reason:8000

[#1]

Have noticed that users that seem to be having problems have a status in their modems stats of:
Status: ShowtimeRetrain Reason:8000
What does this mean? Have done a search on the internet and have found the same question being asked on several other forums without an answer. I have been on the trial 18 days and my status read Showtime but other seen to be getting the above status after being on the trial for 3 or more weeks.
Here is an example
Status: ShowtimeRetrain Reason: 8000
Channel: FAST, Upstream rate = 856 Kbps, Downstream rate = 3072 Kbps
Link Power State: L0
Mode:                  ADSL2+
Channel:                Fast
Trellis:                U:ON /D:ON
Line Status:            No Defect
Training Status:        Showtime
