 through the British Telecommunications Act 1981 which also created the BABT. In 1982 there was a step-change in types of BT phones entering the market, and technology used for connecting phones, and the BABT was needed with a greater variety of phones than was previously available: BT was about to lose its monopoly on supplying phones.

Mechanism of approval

The main four British suppliers of telephones were very wary about supplying to non-BT independent retailers. At the same time BT was introducing its so-called IXT phones (IneXpensive Telephone), designed for the new plug-and-socket connections - another new innovation. Philips
