SUB DUCT AND CABLING. TO ROD ROPE AND TEST, AND INSTALL APPROX 300M OF SUB DUCT AND CABLE AND ANY ASSOCIATED BLOCKAGES IN EXISTING IN FW/CW/VERGE - SPINE ROUTE TO EXCHANGE"an any one here interpret? Please.
desription of work from poster pulling cables along the pavements all around and running them up the wooden telegraph poles, to a new big blackbox on top

A duct can have a sub-duct installed within it. The sub-duct can, obviously, hold cabling (either metallic or glass (or plastic) fibre).
"Rodding" is the process of pushing a semi-flexible rod (either one continuous length from a reel) or discreet lengths, joined together like a chimney sweeps rods and brush, into a duct. Once the rod(s) reach the other end of the duct (so being "rodded") a polypropylene rope (blue coloured) would be attached to a coupling on the "nose" of the rod and the rod(s) pulled back to the point where they were initially inserted, drawing the rope through the duct. The test would be whether the rod(s) could be inserted through that length of duct. Approximately 300 metres of sub-duct (possibly already pre-cabled) would then be drawn into the duct by usage of the polypropylene rope.
If the "rod, rope and test" fails due to a blockage in the duct, the duct would have to be excavated. The existing duct may run under the pavement ("footway" (FW)), the road ("carriageway" (CW)) or verge. Hence notice has been given that excavation my be required in one, two or all three of those surfaces.
The duct route, to which the works refer, is classified as a spine route (a major infrastructure route) to the relevant, nearby, telephone exchange.
As for the "pulling cables along the pavements all around and running them up the wooden telegraph poles, to a new big blackbox on top", without seeing a picture . . . who knows? :shrug2: It is what it is, no more and no less. ;)

This is the enquirer's pic of the pole and big black box. B'cat can you make anything of it?
-
Its a DP. Distribution point/pole. The black box at the top terminates the underground cable that is fed up the pole. The individual drop wires then connect to the screw terminals within the box.
-
Is it probably only a replacement for an old one, and the emquirer is reading some more significant; do you think?
-
Sounds very likely, or just increasing the copper capacity of the DP.

Yes, I would agree. However something else is planned for the area . . . unless the "ROD ROPE AND TEST" was just a training exercise for some new Openreach recruits. :D

Later he posted photos up the pole, showing another contraption on the opposite side from the big black box.
-
I'm not too sure but that may be related to optical fibres, possibly a manifold -- the gubbins from which an optical fibre drop to the premises emanates. If there is a yellow stripe on the cable entering into the bottom of the gubbins then that will confirm the optical fibre connection.

I count 16 wires running from the top of the pole in the first picture, and only 6 in the second....

My thoughts also.
Clearly 2 different poles.

Yes, sorry not to mention, but orig pic was of wrong pole. :-[
