Independent Connection Providers (ICPs) shall be able to complete self-design approval in the majority of circumstances, as outlined in the table below.

At this time, some market segments  have been excluded due to the technical complexity and/or network constraints. We will work with ICPs to develop processes to open these market segments in the future.
