Timing is achieved by transmitting sync characters prior to data. It does not use such redundant information as the start and stop bits in asynchronous transmission to identify the beginning and end of characters and is thus faster and more efficient.
Industry:Technology
A technique for multiplexing several circuits over transmission links and switches whereby time is divided into slots or buckets, and circuits are given time units whether or not they have any data to transmit. See asynchronous transfer mode.
Industry:Technology
SONET (Synchronous Optical Network) is a standard for connecting fiber-optic transmission systems sold in North America only. SONET was proposed by Bellcore in the mid-1980s and is now an ANSI standard. SONET defines interface standards at the physical layer of the Open Systems Interconnection (OSI) seven-layer model. The standard defines a hierarchy of interface rates that allow data streams at different rates to be multiplexed. SONET establishes Optical Carrier (OC) levels from 51.8 Mbps (OC-1) to 9.95 Gbps (OC-192). The international equivalent of SONET, standardized by the International Telecommunication Union (ITU), is called Synchronous Digital Hierarchy (SDH).
Industry:Technology
A network in which all the communications links are synchronized to a common clock.
Industry:Technology
High-speed transmission of contiguous groups of characters. The stream of monitored and read bits uses a clock rate.
Industry:Technology
Having a constant time interval between successive bits, characters or events. Synchronous transmission uses no redundant information to identify the beginning and end of characters, and is faster and more efficient than asynchronous transmission, which uses start and stop bits. The timing is achieved by transmitting sync characters prior to data; usually synchronization can be achieved in two-or three-character times.
Industry:Technology
Gartner defines a synchronized bill of materials (BOM) capability as enabling value chains, including OEMs, suppliers and service organizations (such as electronics manufacturing services), to synchronize different views of items in different BOMs.
Industry:Technology
An initiative originally set up to develop a uniform synchronization protocol operating on any device over any network and among various vendors’ products. The protocol was intended to provide support for a wide range of transports and media types.
Industry:Technology
Establishment of common timing between sending and receiving equipment.
Industry:Technology
A multiprocessor architecture in which all processors are identical, share memory and execute both user code and operating-system code.
