Cityfibre road markings during network build

Hi all,
I'm excited that our area might soon get cityfibre fttp (and openreach is also in planning). I've seen cityfibre contractors using existing ducts and trenching in various streets of the area. I also noticed some markings on the street recently.

I think I can't upload the pictures of them as the file size is too large... But it says stuff like:

"PN Cab and SN can" or "14D" or "20T" with arrows... Any idea what this could mean?

Cheers
 
Road markings are tricky as they can mean different things, depending on the type of utility. Some are normally pretty obvious, but others are much harder, and I've found that different companies sometimes have their own quirks.

If I were to guess, because I've never been able to find a guide that correctly explains them for telecoms works, then I'd say PN is for a power cabinet and SN is for a splitter node. I'd assume 14D and 20T may refer to some elements of distance, direction and trench type - not necessarily in that order. But I could be totally wrong.

The arrows are usually outside each property that is where the toby box will be place (street connection point). Arrows in the path usually show where the micro trenches will be dug and the conduit laid. From what i remember white squares were drawn in the location where the cabinets are.
 
Thanks all. Yeah was thinking that SN and PN might refer to the nodes. Cityfibre seem to use the existing ducts from BT in my stone paved area. The arrows and markings are put down around the BT quadbox covers.
Managed to upload some on a photo sharing page:
 
You'll have Daily Express readers thinking they're markings for burglars and dognappers!

In all seriousness, and in my experience, different organisations choose their own nomenclature so it's hard to decipher. I think Primary Node and Secondary Node makes perfect sense but I'm left guessing at the rest.

Haha good one, Brumski!
Yeah - I could imagine it might have to do with how many T terminations or D dwellings they have in each direction? No clue :)
At least it looks like they are slowly getting our area connected... Then again - another place about a mile away from here also had their streets dug up - but still doesn't appear as available on their website...
At least Openreach also stated via email that their FTTP should be ready to order in about 8 months as well...
Just moved here from a full fibre apartment block and just can't handle FTTC for much longer :D
