Wire signal(Redirected from 92 Code)
A wire signal is a brevity code used by telegraphers to save time and cost when sending long messages. The most well-known of these was the 92 Code adopted by Western Union in 1859. The reason for this adoption was to reduce bandwidth usage over the telegraph lines and speed transmissions by utilizing a numerical code system for various frequently used phrases. 
Several of the codes are taken from The Telegraph Instructor by G.M. Dodge. Dodge notes:
- Other numerical signals are used by different railroads for different purposes, for instance, the signal “47” upon some railroads means “display signals”; while the signal “48” means “signals are displayed”. The numerals “9” and “12” are frequently used for “correct”. Other numerals are used for the different officials’ messages, agents’ messages, etc.
Codes that are not listed in the 1901 edition of Dodge are marked with an asterisk (*).

Today, amateur radio operators still use codes 73 and 88 profusely, and -30- is used in journalism, as it was shorthand for "No more - the end". The Young Ladies Radio League uses code 33 to mean "love sealed with friendship and mutual respect between one YL [young lady] and another YL." The other codes have mostly fallen into disuse.
