In a signal, the changing from one significant condition to another.
Note: Examples of transitions are the changing from one voltage level to another in a data stream, the shifting from one phase position to another in phase-shift keying, and the translation from one frequency to another in frequency-shift keying. [From Weik '89]

The frequency associated with the difference between two discrete energy levels in an atomic system, given by where f 2

Synonym intermediate-field region.

In cryptography, the process of offset decrypting a key or set of keys using a transportation key shared with one center and then offset encrypting the same key or keys under a transportation key shared with a different center. [After X9.28]

Synonym translator.

A signaling point that performs SCCP (signal connection control part) global title translation. It is also known as SCCP Relay Node. The translation performed may be intermediate, in which case the TSP is referred to as "intermediate translation signaling point" (ITSP), or final, in which case the TSP is referred to as "final translation signaling point" (FTSP). [T1.226-1992]

1. A device that converts information from one system of representation into equivalent information in another system of representation.
Note: An example of a translator in telephony is the device that converts dialed digits into call-routing information.
2. A computer program that translates from one language into another language and in particular from one programming language into another programming language.… (Read More →)

To convert the characters of one alphabet to the corresponding characters of another alphabet.

1. The dispatching, for reception elsewhere, of a signal, message, or other form of information.
2. The propagation of a signal, message, or other form of information by any means, such as by telegraph, telephone, radio, television, or facsimile via any medium, such as wire, coaxial cable, microwave, optical fiber, or radio frequency.
3. In communications systems, a series of… (Read More →)

1. A group of bits or characters transmitted as a unit and usually containing an encoding procedure for error control purposes.
2. In data transmission, a group of records sent, processed, or recorded as a unit.
Note: A transmission block is usually terminated by an end-of-block character (EOB), end-of-transmission-block character (ETB), or end-of-text character (EOT or ETX).
