The T1 Telephone series was conceived from two simple concepts, firstly to emphasise the importance of the receiver and its use, and secondly creating a detail which allows the user to place the receiver in any position from the telephone. This receiver rests on a button in the middle of a breast-like form, allowing it to turn and be picked up or put down in any position.

The T1 series consists of four models, of which all but one have an information screen.  The most complex model has a larger information screen which folds onto the keyboard.
