## Features

- TELEPHONE AND SUPERFAST BROADBAND - These cables are perfect for extending both Telephone and Broadband signals around the home. They are compatible with BT Infinity, Sky, EE, Plusnet, Virgin Telephone, TalkTalk and many other Internet Service Providers
- BEWARE OF CHEAP IMPORTED VERSIONS - There is currently a surplus of imitation copper cables on the UK market. Many copies of BT CW1308 cables claim to be manufactured to BT spec but instead use either Copper Clad Steel (CCS) or Copper Clad Aluminium (CCA)
- AVOID SLOW BROADBAND + A QUIET PHONE - Using the incorrect cable can have a dramatic effect on Router speeds and even the volume on your Telephone line. CCS and CCA versions also introduce many connectivity problems associated with corrosion and oxidation

- INCLUDES INSTALLATION ACCESSORIES - All lengths are supplied with an IDC insertion tool, 2 cable protecting drill hole grommets, full colour code installation instructions and matching cable clips. Achieve a professional looking installation at the fraction of your suppliers price

    Does what it says on the package

Everything was good

### ⭐⭐⭐⭐⭐ 







  
  
    Proper replacement phone cable.
  

*by H***L on Reviewed in the United Kingdom on 22 January 2021*

I was suffering from stability from the upstairs router and dedicate phone socket. BT attended at request of my ISP and part of the problem was found to be poor quality cabling from the house's incoming socket to the dedicated socket. The BT engineer gave me guidance on how to replace the cable and with what type of cable. This solid core 2x twisted solid core pair cable does indeed meet BT's specifications (avoid multi-strand cable as this can cause induction properties and with it interference in itself and though cheaper, will cause more problems than resolve).The fitting tool is kind of "meh" but it does do the job of setting up new connections with this cable package, so no real problem and is an added benefit to buying this pack rather than sourcing a more robust one or trying to use unfit tools or ways of making the connections in the socket.All in all, I would be happy to use this again on another property or recommend anyone comfortable playing with thin cables to to do so themselves with their systems.

### ⭐⭐⭐⭐⭐ 







  
  
    Great quality cable and Great Clips too!
  

*by D***R on Reviewed in the United Kingdom on 20 January 2021*

I see from other reviews that some have problematic clips and some have a problem with the IDC insertion tool.I had no such problems.The supplied cable (I ordered 10M white) is very good quality with 2 twisted pairs. The outer sheath is easily to strip and the inner draw cord aids further stripping well. The cable is round in cross section.The IDC tool is all plastic but does the job well with no bending of the tool.The supplied clips hug the cable well and go into plaster easily with no bending of the nails. No need for a trip to the DIY store for further clips.The supplied grommets are made from rigid plastic and appear to be good quality. I didn't need the grommets, as I wasn't taking my cable through a wall.The included "instructions" are a little dated but may be useful for some as a guide to colour coding.All in all very pleased with my purchase.
