21. The system of claim 13, wherein a third of said plurality of translator means comprises: counter means, responsive to signals indicative of a predetermined first particular supervisory signal, for generating a count indicative of the number of sequential occurrences of said first particular supervisory signal in said signal from said telephone set, said count being applied to said memory means as said second code word; and means, responsive to signals indicative of a predetermined set of particular supervisory signals not including said first predetermined particular supervisory signal, for generating said strobe control signal to said means for selectively transmitting in accordance with the occurrence of any of said set of supervisory signals in the signal from said telephone set, to effect transmission of the symbol code indicia from the instantaneously addressed location in said memory means.
