Suggested change

PTP Operator,`ptp-operator/configuration/PtpConfigTBCWpc.yaml`,Configures PTP as a Telcom boundary clock. Dependent on cluster role.,No

PTP Operator,`ptp-operator/configuration/PtpConfigTBCWpc.yaml`,Configures PTP as a Telecom boundary clock. Dependent on cluster role.,No

Typo, right? Same for the next two lines.

well spotted. Thank you

Great work!

I see Lluis is reviewing this for style, just two minor issues regarding content from u/s to d/s:

See this change here that I think isn't carried downstream: https://gitlab.cee.redhat.com/reference-configurations/reference-design-specifications/-/blob/main/telco-ran/telco-ran-rds.adoc?ref_type=heads&plain=1#L1148
Regarding the SiteConfig CR to ClusterInstance CR migration, need an update to this sentence to refer to ClusterInstance CR:

"Representative SiteConfig CR to install single-node OpenShift with the RAN DU profile"

And possibly this sentence needs to be updated because SiteConfig is removed now, not deprecated?

" In earlier releases, a GitOps ZTP plugin supported the generation of installation CRs from SiteConfig CRs. This ~~plugin~~ functionality is now ~~deprecated~~ removed."

Thanks @rohennes

That change you mentioned is in. Must have been included in an earlier release. Its here in the published 4.20 RDS https://105488--ocpdocs-pr.netlify.app/openshift-enterprise/latest/scalability_and_performance/telco-ran-du-rds.html#telco-ran-cluster-tuning_telco-ran-du
updated with SiteConfig with ClusterInstance
rewrote that line -> "This plugin is now removed."
