One of the problems faced in setting up such a worldwide system was that of standardizing the code and operating speed. At the time of Kleinschmidt’s stay in London in 1930 to close negotiations with Creed for the sale of Morkrum-Kleinschmidt’s foreign rights, he met Mr. Martin Feuerhahn of the German Telegraph Administration who at that time was in conference with Creed and representatives from the British Telegraph Administration as to standardizing on an alphabet and telegraph code for international communications. Mr. Feuerhahn argued for the adoption of the American Murray alphabet and code, stating that he already had the approval and consent of the French, Italian, and Belgian telegraph administrations. Mr. Feuerhahn and Kleinschmidt spent some hours together. After their return to their respective countries, Kleinschmidt received a letter from Mr. Feuerhahn referring to their talks and stating that he had been in correspondence with Mr. Benjamin of Western Union and Mr. Parker of Bell Laboratories with regard to code and other pertinent matters of standardization so that an International Teleprinter Exchange could be extended into the United States. Another letter dated October 10, 1931, reviewed the aforementioned standardization search. The Murray alphabet and 7½-unit code were soon adopted and are still in use today in TELEX. In later years, an association, the Consultative Committee on International Telegraph (CCIT—now the CCITT to include the telephone), was formed and met regularly to discuss problems and to set operating regulations for the TELEX apparatus in an intercommunicating system. The CCITT at this writing is still meeting regularly on worldwide standardization in both telegraph and telephone communications. _TELEX IN THE UNITED STATES AND TWX_ In the United States, in November 1931, the Bell Telephone Companies announced an intercommunicating teletypewriter service, called TWX for short (_T_eletype_W_riter e_X_change), by which interconnections could be made by a switchboard operator as in telephone service. One of their first advertisements named it a “Telephone Typewriter Service, a service that typewrites by wire, a method of inter-office communication that has the quickness of the telephone, the flexibility of conversation, the accuracy of the typewriter, the authority of the printed word, the permanency of print.”[13] Tape-punching and tape-controlled transmitting apparatus was provided. This service allowed subscribers to carry on a typewritten conversation at a charge less than the cost of a telephone call, whether to local or to distant areas. The maximum speed of this equipment was limited to sixty words per minute.
