@HP,
The deployment order usually starts from the fibre aggregation point often choosing ongoing routes that are not blocked or jammed full of cables using a larger multi-tube "cable". That often drops down to a smaller one on longer ones, down to the smallest being a quad-tube one feeding two in-line cabinets as the maximum. Obviously a cabinet can't be commissioned before there are continuous tubes all the way back to the aggregation point / distribution node.
RFS dates seem to jump by 3 months for installations, but can just as easily complete much earlier. Capacity issues seem to jump by a single month, but again can complete earlier or get postponed yet again. All that is reasonably certain is that FTTC services will become available at some point, once any date is actually announced. If you are one of the unfortunates on longer D side lines don't forget to try a number much closer to the FTTC as it's tough luck for the very long ones, but the shorter ones will always have a RFS date once the FTTC is nearly completed.
Kind regards,
Walter
