A few more comments from me
Im unsure if (FTTC) fibre would be in the ducts at the beginning of your video*. If the A30 is carring the main backhaul it cant just branch off anywhere and needs some sort of main junction before it can split off into smaller metwork segments. Think of it like your router then serving various equipment in your home.
A telephone exchange is the usual point where all the network equipment such as the FTTC/FTTP OLT (Optical Line Termination) and switches reside.
Some info: -
Full line info isnt showing up on the BTw database, which usually indicates LLU - so could AAISP be provisioning it using TT?
Served by Cab 2 on Cardinham which is an ECI cab provisioned Phase 9a BDUK Cornwall in April 2013
Cardinham is a small exchange with only 2 PCPs - all the rest are EO Lines.
From info Ive tried to piece together from the cab photo in the video it looks like the FTTC cab is on the corner junction at PL30 4DB and about 1 km from the farm.
According to my checker the total line distance is apprx 2.5 km from Cardinham exchange.
However, Cardinham is NOT a headend exchange. BODMIN is the nearest headend exchange that has an FTTC OLT. Therefore the fibre to your FTTC cab will directly feed back to Bodmin and not to Cardinham.
The most likely the fibre link to your cab will go along the A38, (probably branching off at Turfdown Road) as Bodmin appears to serve as the headend for several smaller local exchanges such as Dobwalls, Liskeard etc.
*Noted that Cardinham has not yet been updated to 21CN so it may contain old 20CN ATM MiSP links to say Reading RAS which are totally inadequate for Fibre broadband traffic.
21CN - which is required for FTTC, doesnt work like that and goes through a series of Nodes with a more local MSE bRAS and then on to a WDM backhaul capable of much higher bandwidth.
Sorry for the super late reply, I used to live in a place called East Taphouse, and Dobwalls, and have now moved to Cheshire.
There is a BT exchange of some kind in Dobwalls, it's on seperate building with vans outside etc.
Dobwalls feeds off Liskeard.
It was common knowledge in the area that the DF for the country ran up the A30.
It was also "guessed" knowledge that fibre ran alongside the high pressure gas pipeline that went through East Taphouse and past Dobwalls etc in a straight line. that line was no where near Bodmin.
Here is a pic of the BT "setup" in Dobwalls.
I have also drawn a general route/direction of the gas pipeline.
Hope that helps.
Also, I used to be on EO line, ADSL, from East Taphouse (other end of village from where I have shown green cab is) to the Dobwalls exchange, I could only get 56k for YEARS, then one day we got 1mbps adsl, then a few years later a free upgrade to 2mbps, then 4 years or so ago FTTC.
