This cable is used for and works well for voice and ADSL as its twisted pair construction provides some resistance to interference. As the CW1308 cable is essentially the same spec cable is used throughout the whole telephone network, it known to work well.his cable is used for and works well for voice and ADSL as its twisted pair construction provides some resistance to interference.
