MTK-2
MTK-2 (actually in Cyrillic letters: МТК-2 международный телеграфный код 2 ) is a 5-bit character encoding that was introduced in 1963 in the Soviet Union to represent Cyrillic letters in telegrams. It extends the CCITT-2 code by a third level of characters for Cyrillic letters and replaces some special characters in order to accommodate additional Cyrillic letters. The letters Ё and Ъ are missing ; the letter Ч has been replaced by the number 4.

Standard-compliant representation of telex characters in CCITT-2 and MTK-2. The punching as well as the dispatch of the telex code takes place: Start-1.FsZ-2.FsZ .- (transport punching) -3.FsZ.-4.FsZ.-5-FsZ.-1.5 stop steps.
In the table on the left the sequence is shown alphabetically according to CCITT-2 . In the table on the right, the telex characters are sorted according to their value, i. H. The letter E has the perforation 1-0 -.- 0-0-0 - this corresponds to 1 in decimal.
