if i understood correctly, the drops remain AFTER the site is up (tch avail = 100%).
If you do a lock/unlock of BTS, do the drops disappear ?
If you do a full restart of the BTS/Abis, do the drops disappear ?
If you recreate the BTS/cells from scratch in the OMCR, does the drop disappear ?
There is no “good” reason why the cells remain degraded. I can only suspect a hanging sw somewhere.
By the way, what are the CAUSE of the drops ? Radio ? HO ? remote TC ? BSS Internal ?
