PTT HOMEVOX

The Homevox Universal of Dutch PTT Telecom is a modern digital telephone exchange for homes and small businesses. My version is a 2-6F. This means that it has 6 internal lines and 2 external lines. A wide range of functions can be programmed. The Homevox can be used for pulse dialling and tone dialling, but it does not convert pulse to tone. 

It looks big in the picture but the actual dimensions are 30 x 25 x 6 cm.
