PlusNet might want to consider re-wording both the Trial Application & FAQ pages with regard to the install process.
Currently they speak of 2 engineer visits. However, a new method of installation (known as "connectorisation") requires only one visit. It's what I'm expecting after watching OR install a DP in the underground chamber near my front door.
Re: FTTP Documentation
Not clear that 'connectorisation' is standard practice across all areas of BTOR yet, but it is an optimistic thing to look forward to.
I found this link from June 2016 that covers the topic quite well.
