DECT TN's Show BUSY while doing a stat

[intelligentium]

Can anyone help.
Dect TN's stat busy and appear twice at 1 and 26. While doing an LD 80 trac on the virtual TN, It shows IDLE. Have tried to out the VTN. But then while we do a stat again on the DMC again the 26 dmc unit is showing BUSY.

.stat 96 0 7
