Thanks for the reply, Max. You
confirm what I assumed.

We only have one fibre option : Airband. They "plan" to
connect us tomorrow... We will keep BT phone and VDSL
in parallel for a while - until we are sure AB fibre is
We are exposed to high winds, so I hope the overhead fibre

Will there be delay and/or reduced download data rate as the ISP
resyncs on reconnection?
As far as I know the whole "re-syncing" thing (I think you are
referring to DLM or Dynamic Line Management as it's known here
in the UK) only ever related to copper circuits and particularly
those supplied by BT. Not all ISPs used it (TalkTalk for example
I believe did not - I had a TalkTalk ADSL line at one point via
Andrews and Arnold) and I never saw this behaviour.
Anyway, I digress. It only applies to ADSL (and VDSL - fibre to
cabinet). No such equivalent exists or indeed is needed on a
full fibre line. It will either work at full rate or zero i.e.
usually a break in the fibre, as we did have once due to fallen
tree on the lines. I have full fibre and it's either on (160
MB/s for me) or it's off. Regarding cables, certainly if you do
request to retain your "normal" phone line, they install a fibre
cable that also contains a copper circuit. I'm not 100% sure if
mine does or not because we never requested to keep the copper
(we use VOIP). I don't think it does because I think the "dual"
cable is figure 8 with copper running down the side and ours is
not. Although BT Open Reach who came to connect the service did
not take away the old copper lines despite me asking them
to....... "not our job.... different department"....... typical!
