Thanks Pix,
There was no major degradation in KPIs DCR, SD Drop etc.
Only the UL/DL Quality HO%, which increased from about 5% to 9%
Also, hopping was deactivated before this change.
No priority has been given in terms of shifting traffic to hopping or nonhopping trxs, but generally emphasis is on pushing traffic on 1800, which is now all hopping.
Congestion rate is around 3% at Busy Hour.
I am looking into the parameters, I think i am going to go ahead with three hopping lists (1 x 3) instead of one on the 1800 (1 x 1), and see the effect.
