SATURN Development Group
The SATURN Development Group was an important industry forum that enabled the specification of chip-to-chip interfaces for the communications industry. It was co-founded in 1992 by PMC-Sierra and Sun Microsystems. Several significant specifications were completed through its actions including PL-2, PL-3, and PL-4. Many important semiconductor devices were developed to these specifications. SATURN was also influential in the specification of the ATM Forum's physical layer "UTOPIA" standards. Initial members included SynOptics and Interphase. The first meeting was held in April 1992. By August 1993, the SATURN group had 28 members. After the formation of the Optical Internetworking Forum (OIF), two of the SATURN group's interfaces were successfully adopted by OIF. The PL-3 specification became SPI-3 and the PL-4 specification became SPI-4.2 SPI-4.2 is a version of the System Packet Interface published by the Optical Internetworking Forum. It was designed to be used in systems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industry Forum
A trade association, also known as an industry trade group, business association, sector association or industry body, is an organization founded and funded by businesses that operate in a specific industry. An industry trade association participates in public relations activities such as advertising, education, publishing, lobbying, and political donations, but its focus is collaboration between companies. Associations may offer other services, such as producing conferences, holding networking or charitable events, or offering classes or educational materials. Many associations are non-profit organizations governed by bylaws and directed by officers who are also members. In countries with a social market economy, the role of trade associations is often taken by employers' organizations, which also take a role in social dialogue. Political influence One of the primary purposes of trade groups, particularly in the United States, is to attempt to influence public policy ...

ATM Forum
The ATM Forum was founded in 1991 to be the industry consortium to promote Asynchronous Transfer Mode technology used in telecommunication networks; the founding president and chairman was Fred Sammartino of Sun Microsystems. It was a non-profit international organization. The ATM Forum created over 200 implementation agreements. History In 1996 ATM technology stabilized with the "Anchorage Accord", which established the baseline of ATM implementations. While ATM did not live up to every expectation, it remained an important core network technology. The Frame Relay Forum (promoting Frame Relay) also started in 1991. The MPLS Forum (which supported Multiprotocol Label Switching had begun in 2000. Those two merged in 2003 to become the MPLS and Frame Relay Alliance (MFA). In 2005, the ATM Forum joined forces with the MFA to form the MFA Forum, which was renamed to be the IP/MPLS Forum. In May 2009 the IP/MPLS Forum merged with the Broadband Forum.

SynOptics
SynOptics Communications was a Santa Clara, California-based early computer network equipment vendor from 1985 until 1994. SynOptics popularized the concept of the modular Ethernet hub and high-speed Ethernet networking over copper twisted-pair and fiber optic cables. History SynOptics Communications was founded in 1985 by Andrew K. Ludwick and Ronald V. Schmidt, both of whom worked at Xerox's Palo Alto Research Center (PARC). The most significant product that Synoptics produced was LattisNet (originally named AstraNet) in 1987. This meant that unshielded twisted-pair cabling already installed in office buildings could be re-utilized for computer networking instead of special coaxial cables. The star network topology made the network much easier to manage and maintain. Together these two innovations directly led to the ubiquity of Ethernet networks. Before the final standard version of what is known today as the 10BASE-T protocol, there were several different methods and stan ...

Interphase
Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A cell in interphase is not simply quiescent. The term quiescent (i.e. dormant) would be misleading since a cell in interphase is very busy synthesizing proteins, copying DNA into RNA, engulfing extracellular material, processing signals, to name just a few activities. The cell is quiescent only in the sense of cell division (i.e. the cell is out of the cell cycle, G0). Interphase is the phase of the cell cycle in which a typical cell spends most of its life. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions. Interphase was formerly called the resting phase. However, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SPI-3
SPI-3 or System Packet Interface Level 3 is the name of a chip-to-chip, channelized, packet interface widely used in high-speed communications devices. It was proposed by PMC-Sierra based on their PL-3 interface to the Optical Internetworking Forum and adopted in June 2000. PL-3 was developed by PMC-Sierra in conjunction with the SATURN Development Group. Applications It was designed to be used in systems that support OC-48 SONET interfaces . A typical application of SPI-3 is to connect a framer device to a network processor. It has been widely adopted by the high speed networking marketplace. Technical details The interface consists of (per direction): * 32 TTL signals for the data path * 8 TTL signals for control * one TTL signal for clock * 8 TTL signals for optional additional multi-channel status There are several clocking options. The interface operates around 100 MHz. Implementations of SPI-3 (PL-3) have been produced which allow somewhat higher clock rates. ...
