Exchange has been live since June.
It would seem a bit pointless applying power to a line that hasn't been terminated at the exchange, likewise one that requires a node.
I've no idea how long it takes to test a line. Three weeks seems a little excessive though.
I could ask nga.enquiries but they don't seem to like answering enquiries. It's all very hush- hush you know.
I'm sure you're right. They have lost more possibilities.
