Hi,
It’s just 2/2/2 configuration, not 3/3/3, so your 1st part was enough :
s1,2,3 trx0: nonhopping
s1 trx1 = 0
s2 trx1 = 2
s3 trx1 = 4
By the way,
you’re having 3 hopping TRX on this site, and a MA list of 12 ARFCN.
So that gives a RF load of 3/12=25%, which is quite high (typical target is below 20%). If neighbours are nearby (urban area), then you can expect high interference during Busy Hour, when the second TRXs are loaded to 100%.
If site is located in a rural area, then it should be fine.
Regards,
