Sockets to extend telephone and VDSL to upstairs
« on: February 16, 2021, 10:54:50 PM »

A friend is getting speeds less than he should.

Current set up (see attached):T elephone duplex adapter plugged in to master with (1) Dangly filter in to which DECT base station is plugged and (2) Telephone extension cable (believed to be flat not twisted pair) to office upstairs - it has three cores connected (i.e. bell wire!) In the office he has a filter with his router and a hard wired telephone handset which he wishes to keep.

He's happy to run a UTP 2x2 cable upstairs so I'm suggesting be replaces the front plate on the master with a filtered face plate in to which he can plug the DECT base station (data socket left empty). One pair of the replacement cable connected as telephone extension and the other pair connected to the data connections to corresponding sockets upstairs.

I've lost track of which are the recommended filtered face plates now - NTE 5C MK4?

Can someone point me to a suitable unit for upstairs? I think I've seen modular units before - is there a ready made one with data and telephone (no filter)?

A 32 year old NTE5/A is far preferable to the current NTE5C. (The NTE5/A fitted in "The Cattery" is about 39 years old!  :D  )

He will need to source a Mk 3 SSFP to fit the NTE5/A. (The Mk 4 SSFP, which fits the NTE5C, is identical in components but inferior in build quality.) Here is an example, on eBay.

For the upstairs office, I will suggest --

Thanks for that.

Where the cable run ideally has to go is partly under carpet so he was thinking of routing a channel across the floor so it is less vulnerable. To minimise the size of the channel using as thin as possible cable would be preferable. As he only needs 2 pairs, do you know if there is such a thing as 4-core, if so is it any good and where can you get it from? I've already told him that people frequently use CAT 5e which will have more pairs than he needs.

CW1308 from all the usual sources.

I will recommend using the "proper stuff". I.e. CW1308 specification cable, containing two twisted pairs. It will either have wires blue & orange --> pair one and green & brown --> pair two OR blue/white stripe & white/blue stripe --> pair one and orange/white stripe & white/orange stripe --> pair two.

I'd be cautious of doing something like that, might not meet building regulations.  If you're messing with the floor anyway its best to take it underneath or run it along skirting boards.

Does the CW1308 specification allow for flat (untwisted) cables or does it have to be twisted?

Oh no, that looks a bit flat. It certainly isn't CW1308 which is round and has twisted pairs. Send it back. >:(

Agree - you don't wanting to be using that as an extension cable as it'll likely degrade the signal.

The description on eBay includes

PLEASE NOTE WE TAKE OUT OF RETAIL PACKAGING TO SAVE POSTAGE COSTS

Like hell they do - the cores aren't even the same colouring as the picture on eBay.

I think they probably buy the cheapest they can in bulk and cut to length.

I told him to send it back straight away.

Hopefully as item not as described, that way he doesn't have to pay the postage.

I'd only use a known reputable supplier for CW 1308 - been caught out in the past with round, twisted pair that looked just the part, but a resistance test on the reel showed it was probably copper-clad aluminium.   >:D

The other supply scam is copper-clad steel.  >:(

I have a 7m "CAT 7" from Amazon that is so stiff I wouldn't be surprised if its that.  It will only link at 5Gbit max which is highly suspect.
