With SET GCELLCCTMR command I did not find the N200 parameter (all the other are ok).

Dear Ahmed,

Actually our network ring topology is set to "RING I" and not "RING II". As I understand, to configure N200 to 3, I have to reconfigure the topology to "RING II" by "FASTCNETFLAG=YES".

What are the differences between "RING I" and "RING II" topology.
Is there any risk when changing the Ring topology configuration.
As I understand I have to change the topology for the hole network, isn't ?
Any recommendation ?
