Produced for BT by STC, this was another phone launched in 1981 onto the newly liberalised market. The New Electronic Telephone (NET) or Viscount as it was named, was best suited to domestic use. Its main flaw was that it was possible for the handset to be replaced on the rest in a way that broke the loop, but left the ringer disconnected. This would lead to complaints that nobody was answering the phone. This problem was eventually fixed, but by that time many phones in the field would have remained unmodified.
