The Openreach spreadsheet showed Llangoed as being live from Weds. So some cabs must be able to order already.
Keep a close eye on the checker as the exchange cab could go live anytime, may already be live.
There can be issues with getting suppliers to take orders on EO lines as the copper also has to be moved to the new cabinet. The checker
will tell you if you are one of the lucky ones atomatically moved. (it will now show a cabinet number).
