Open Source for Open Telecom
Advancing CompactPCI and PC-based Telecommunications
This site is devoted to Open Source (tm) software for computer telephony, specifically focusing on hot-swap and circuit switching capabilities for systems built with CompactPCI and the H.110 CT Bus.
CompactPCI is a standard for rugged PCI-based computers produced by the PCI Industrial Computer Manufacturer's Group (PICMG). Despite a rugged industrial form-factor, CompactPCI equipment is electrically and software compatible with desktop PCI computers. H.110 is a telecom bus defined by the Enterprise Computer Telephony Forum (ECTF) for the transport and switching of telecom data streams (typically n x 64 kbps) between cards in a CompactPCI chassis. The H.110 bus has a counterpart for desktop PCs called the H.100 bus.
The current standards were adopted early in 1998 and first products appeared in 1998. While early products have been electrically and mechanically compatible, little software exists to allow developers to take advantage of the new capabilities. We seek to solve that problem and foster the growth of computer telephony based on CompactPCI and H.100/110.
Is This Useful with Regular PCs_
CompactPCI computers are software-compatible with desktop PCs (except for the extra ability to "hot-swap" boards while the computer is running). Obviously the hot-swap software will not be directly useful in desktop PC applications. However, all of the circuit switching that applies to the H.110 telecom bus also works with desktop systems using the H.100 bus or earlier telecom buses such as the MVIP Bus from the Global Organization for Multi-Vendor Integration Protocol (GO-MVIP).
What is OpenTelecom_
OpenTelecom is a loose consortium of individuals and companies interested in using widely available computer technology to build new telecommunications equipment and services. Everything shared at this site is Open Source (tm). Our immediate focus in on software for "Hot Swap" and for "Telecom Circuit Switching" in systems built with CompactPCI and desktop PC computers. For now, this web site is being subsidized by Natural MicroSystems.
