The PCB in my Genie says 'UK Genie' on it. It is clearly designed for the UK Plug 431A wiring, with the ringing capacitor in the master socket rather than the telephone. And it is LD (pulse) dialing only.

There would be no obvious way to make it DTMF dialing, although the TEA1061 speech chip has inputs for a DTMF dialer, they are not used. I think if there was a DTMF version it would be a totally different PCB.

All the references I can find to the TSR (Telephone Special Range) 8023 (which is the Genie with last number redial) and 8022 (without redial) say they are LD only. I can find no mention of a Genie in the TSR lists which is DTMF.
