Shipment claims are so far ahead of sales that need an explanation. Nokia is proud they won the G.fast order from Frontier in Connecticut, a U.S. company with over 4M DSL & fiber subscribers at the end of Q1. They gave no details of when, where, or how many, so it wasn't worth a headline. (PR below)
The interesting thing in the release is the claim they've shipped, "30 million vectoring lines." I'd be surprised to discover that even 10% of those are actually deploying vectoring. Similarly, Adtran claims 10M vectored. (PR below) There are remarkably few vectored lines in service. The claimed vectored ports are probably 10x or more the number of actual vectored lines.
There just aren't many homes connected with vectoring.
