PICMG 2.15
PICMG 2.15 is a specification by PICMG that defines specialized telecom interfaces for PMC cards. Later, PICMG 2.15 was revised via ECN001 to add enhanced TDM capacities by extending the TDM (H.110) bandwidth and adding Ethernet Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN).

PICMG
PICMG, or PCI Industrial Computer Manufacturers Group, is a consortium of over 140 companies. Founded in 1994, the group was originally formed to adapt PCI technology for use in high-performance telecommunications, military, and industrial computing applications, but its work has grown to include newer technologies. PICMG is distinct from the similarly named and adjacently-focused PCI Special Interest Group (PCI-SIG). PICMG currently focuses on developing and implementing specifications and guidelines for open standards-based computer architectures from a wide variety of interconnects. Background PICMG is a standards development organization in the embedded computing industry. Members work collaboratively to develop new specifications and enhancements to existing ones. The members benefit from participating in standards development, gain early access to leading-edge technology, and forging relationships with thought leaders and suppliers in the industry. The original PICMG ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PCI Mezzanine Card
A PCI Mezzanine Card or PMC is a printed circuit board assembly manufactured to the IEEE P1386.1 standard. This standard combines the electrical characteristics of the PCI bus with the mechanical dimensions of the Common Mezzanine Card or CMC format (IEEE 1386 standard).{{Cite book, title=1386-2001 - IEEE Standard for a Common Mezzanine Card (CMC) Family - IEEE Standard, language=en-US, doi=10.1109/IEEESTD.2001.93280, isbn=978-0-7381-2829-0 A mezzanine connector connects two parallel printed circuit boards in a stacking configuration. Many mezzanine connector styles are commercially available for this purpose, however PMC mezzanine applications usually use the 1.0 mm pitch 64 pin connector described in IEEE 1386. A PMC can have up to four 64-pin bus connectors. The first two ("P1" and "P2") are used for 32 bit PCI signals, a third ("P3") is needed for 64 bit PCI signals. An additional bus connector ("P4") can be used for non-specified I/O signals. In addition, arbitrary conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TDM Bus
A TDM bus is one application of the principle of Time-Division Multiplexing. In a TDM Bus, data or information arriving from an input line is put onto specific timeslots on a high-speed bus, where a recipient would listen to the bus and pick out only the signals for a certain timeslot. It resembles the TDM carried out in synchronous optical networking, but the "TDM Bus" term is more commonly used when the bus is inside a single unit like a telecommunications switch or a PC. A specification for putting a TDM bus on PCI hardware has been published as H.100/H.110 by the Enterprise Computer Telephony Forum (ECTF). last accessed 2007-02-04] These are not related to the |
Ethernet
Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the latest , with rates up to under development. The Ethernet standards include several wiring and signaling variants of the OSI physical layer. Systems communicating over Ethernet ...

Open Standards
An open standard is a standard that is openly accessible and usable by anyone. It is also a prerequisite to use open license, non-discrimination and extensibility. Typically, anybody can participate in the development. There is no single definition, and interpretations vary with usage. The terms ''open'' and ''standard'' have a wide range of meanings associated with their usage. There are a number of definitions of open standards which emphasize different aspects of openness, including the openness of the resulting specification, the openness of the drafting process, and the ownership of rights in the standard. The term "standard" is sometimes restricted to technologies approved by formalized committees that are open to participation by all interested parties and operate on a consensus basis. The definitions of the term ''open standard'' used by academics, the European Union, and some of its member governments or parliaments such as Denmark, France, and Spain preclude open standard ...
