I’ve got many cells in MBC configuration, Alcatel vendor, in different BSC) which acts very strange.
In one cell i’ve got the stats below at busy hour:
52 TCH available, 40 busy TCHs and 13% of TCH congestion.
Of course it’s not a normal behaviour. I look for reasons of congestion with counter MC612A , MC612B, MC612C and MC612D. Only MC612A got incremented which means that NO AVAILABLE TCH AND QUEEING IS NOT ALLOWED(in documentation).
U see the problem???
I really really need ur help to resolve this issues.
