Title: How scaffolding can interfere with your line
Post by: Alex Atkin UK on April 17, 2018, 02:05:15 PM
Got an interesting one today, not exactly a fault but a curiosity I thought some people might be curious to hear about.

Had a roof repair and they put scaffolding up right against the phone line pulling it really tight.

Not sure if its permanently slightly impaired the line (I'm hoping not, the overhead cables are pretty tough) but it was very interesting what it did to my upstream SNRM.  Presumably the scaffolding was acting as an antenna and broadcasting a ton more crap into the upstream bands.

It's certainly a distinctive effect. Just to be clear, was the scaffolding erected at approximately 1010 hours and removed shortly after 1320 hours?  :-\

Unfortunately you haven't got reconnect and I will not see possible difference in Hlog.

I didn't note the exact time they erected but it sounds right and the fact its completely reverses at the time they removed it just makes sense.

Interestingly it didn't drop sync when they erected it but did when the removed it.  Not looking any worse for wear though.

That would be not unlike my own theories about possible changes to my lines which are lying on the ground, or buried in soil, or lying in water sometimes and not others and in ice sometimes and not others.

Added photo of the line.

Those scaffolders should be ashamed of themselves.

You should have seen what the people did who replaced the old Windows.  They wedged the cable around the side of the Window frame then cut a hole out of the trim to fit it around the junction box.

If anyone asks I did NOT disconnect it, drill a hole through the wall and wire it back up directly into the master socket.  ::)  Funnily enough, BT contractors later came round and applied silicon around the hole, presumably assuming the contractors had done it.

Kelly Communications have inspected it since as I temporarily had a second line fitted by Origin Broadband.

Someone else I know I believe they completely disconnected the master socket as when they had done it had been screwed back on the wrong way around and there was no dial tone.  The latter might be a coincidence though as it was an inactive line but had previously still been getting a dial tone.
