Definitions of out-of-band word

noun Technical meaning of out-of-band 1. (communications) The exchange of call control information on a dedicated channel, separate from that used by the telephone call or data transmission. 2. Sometimes used to describe what communications people call "shift characters", such as the ESC that leads control sequences for many terminals, or the level shift indicators in the old 5-bit Baudot codes. 3. In personal communication, using methods other than electronic mail, such as telephone or snail-mail. 4. (software) Values returned by a function that are not in its "natural" range of return values, but rather signal some kind of exception. Many C functions that normally return a non-negative integer return -1 to indicate failure. This use confuses "out-of-band" with "out-of-range". It is actually a clear example of in-band signalling since it uses the same "channel" for control and data. Compare hidden flag, green bytes, fence. 1
