| ZBR |
Zero Bit Reduction. |
| ZD |
Zero Defects. |
| Zero Bit Insertion |
A technique whereby additional "zeros" are inserted after a fixed number of "ones" in a transmission sequence to ensure that data will not be misinterpreted as controlling information. |
| Zero Byte Time Slot Interchange |
A control technique used in specific T1 systems in which information on the location(s) of all-zero bytes is contained in a defined area of the transmission frame. |
| Zero Code Suppression |
A technique used to prevent the existence of eight consecutive zeros in a digital transmission frame. A number of different schemes are used. The process is essential for the proper operation of most T1 (and above) digital transmission systems. |
| Zero Delay Lockout |
Technology designed to prevent beaconing stations from entering into a Token Ring by locking out faulty stations. |
| ZIF |
Zero Insertion Force. |
| ZIP |
Zigzag Inline Package |
| Zodiac |
An early network architecture used by Data General. |
| Zweiton |
A technique of implementing stereo or dual-mono audio for NTSC and PAL video. One FM subcarrier transmits a L+R signal, and a second FM subcarrier transmits a R signal (for stereo) or a second L+R signal. It is discussed in BS.707, and is similar to the BTSC technique. |
