Re: Edit to DTMF Page
"operator terminals had 16 keys and were not few..." - Can you please explain? I'm not familiar with the operator terminals you reference. Do you mean TSPS, Cord, something else? My understanding is that the ABCD functions were never produced in any volume except for Autovon. Please enlighten me. Lexlex (talk) 01:40, 11 August 2011 (UTC)
