Abstract: A small, portable, dialed number printout unit is provided which can be used in central offices or at the subscriber''s premises to provide a print of the called number in numerical form on a record medium as soon as this number is dialed by the calling party. Printout of the called number will automatically occur approximately 20 seconds after the last digit is dialed or upon hang-up, whichever is sooner. Facilities are also provided for selectively printing only those dialed numbers which have a predetermined number of digits and rejecting all dialed numbers having digits greater or less than said predetermined number. A false digit appearing on the line before dialing is started may be automatically absorbed and not printed. Facilities are also provided for automatically advancing the record medium a predetermined amount after each printing operation such that the printed called number is immediately visible to an attendant.
