Novation CAT - The D-CAT

The D-CAT

A direct-connect version of the original 300 bit/s external modem was later released as the D-CAT (D for direct). To operate the D-CAT, an external telephone was still required to dial. Once the connection was made, a button was pressed on the modem which made it "pick up" the phone, at which point the handset could be hung up. A further improvement was the Auto-CAT, which allowed dialing the phone by entering the number when the modem was first started. Once the connection was made the modem switched to "data mode", and from then on had to be operated manually.
