TELEX CODES

[D.J.J. Ring, Jr.]

Remember these coast station operators?

TELEX CODES ~ what fun! In the USA if you didn't get the right telex code, you wouldn't reach the subscriber, there was TRT, FTC, WUI  Western Union International, MCI, WUD Western Union D (Domestic), ITT, ... Plus each nation had their own code. The wireroom people really earned their pay. (Usually the midwatch radio officer had to man the wireroom too, but we were the highest paid employees because we had a telegraph license.)

230 UD USA (AT&T)  
231 UT USA  (TRT/FTC)  
232 UR USA  (MCI/WUI)  
233 UB USA  (GRAPHNET)  
234 UI USA  (AT&T)  
235 USA (AT&T EasyLink Services Network)  
236 UW USA (MCI/WUI)  
237 UC USA (CCI)
238 UF USA (TRT/FTC)  
239 UE USA (TELENET)

UI Used to be ITT but how things have changed, I don't even know if telex exists, TRT (WNU Slidell Radio) is now the same as French Telegraph Company (FTC), who would have guessed. Western Union Domestic (UD) is also now AT&T.

At GKA in our landline room we had a wall chart with all the telex country codes - and for the USA each particular carrier could be identified by the first couple of digits, or the length of numbers in the landline telex number. 

We used Post Office Type 15 teleprinters (see photo) which also needed a 'chad clearance' every day by the station Maintenance Officer, who also checked the printer ribbons and made sure the rolls of paper were regularly topped up. When GKA installed the new computerised message handling system, the old Type 15 printers were removed and replaced by 'Trend' machines which incorporated a word processor and would deliver messages by telex directly from the w/t working point, making the old landline room redundant.

In the new operational building, the radio telex area had their own computerised system whereby the ship would simply type in DIRTLX followed by the telex number and the + sign, and the system would connect the radio link to the telex number automatically. All on VDUs without an old telex machine in sight. 

Previously the Type 15 machines were used with manual switching from the RTT Marconi Spector units (2 circuits per R/O).

[Dr Jim Kennedy]

Do not for get the 29, 33 and 38 machines as well.
