The IBM 3270 is a family of block oriented display and printer computer terminals introduced by IBM in 1971 and normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. Due to the text color on the original models, these terminals are informally known as green screen terminals. Unlike a character-oriented terminal, the 3270 minimizes the number of I/O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable.
3Com Corporation was an American digital electronics manufacturer best known for its computer network products. The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others. Bill Krause joined as President in 1981. Metcalfe explained the name 3Com was a contraction of "Computer Communication Compatibility", with its focus on Ethernet technology that he had co-invented, which enabled the networking of computers.
Micro Channel architecture, or the Micro Channel bus, is a proprietary 16- or 32-bit parallel computer bus publicly introduced by IBM in 1987 which was used on PS/2 and other computers until the mid-1990s. Its name is commonly abbreviated as "MCA", although not by IBM. In IBM products, it superseded the ISA bus and was itself subsequently superseded by the PCI bus architecture.

The parent company, Stratus Technologies Bermuda Holdings, Ltd., was incorporated in Bermuda. In 2022, the company was acquired by Smart Global Holdings (SGH) and currently operates within SGH's Intelligent Platform Solutions (IPS) business.
In computing, remote direct memory access (RDMA) is a direct memory access from the memory of one computer into that of another without involving either one's operating system. This permits high-throughput, low-latency networking, which is especially useful in massively parallel computer clusters.
GammaLink Inc. was an American computer hardware and software company founded in the 1980s in Sunnyvale, California, by Hank Magnuski and Michael Lutz. The company was the first to invent PC-to-fax communications technology, GammaFax.
Skype for Business Server is real-time communications server software that provides the infrastructure for enterprise instant messaging, presence, VoIP, ad hoc and structured conferences and PSTN connectivity through a third-party gateway or SIP trunk. These features are available within an organization, between organizations and with external users on the public internet or standard phones.
Madge Networks NV was a networking technology company founded by Robert Madge, and is best known for its work with Token Ring. It was a global leader and pioneer of high-speed networking solutions in the mid-1990s, and also made significant contributions to technologies such as Asynchronous Transfer Mode (ATM) and Ethernet.
Mwave was a technology developed by IBM allowing for the combination of telephony and sound card features on a single adapter card. The technology centers around the Mwave digital signal processor (DSP). The technology was used for a time to provide a combination modem and sound card for IBM's Aptiva line and some ThinkPad laptops, in addition to uses on specialized Mwave cards that handled voice recognition or ISDN networking connectivity. Similar adapter cards by third-party vendors using Mwave technology were also sold. However, plagued by consumer complaints about buggy Mwave software and hardware, IBM eventually turned to other audio and telephony solutions for its consumer products.
In systems management, out-of-band management is a process for accessing and managing devices and infrastructure at remote locations through a separate management plane from the production network. OOB allows a system administrator to monitor and manage servers and other network-attached equipment by remote control regardless of whether the machine is powered on or whether an OS is installed or functional. It is contrasted to in-band management which requires the managed systems to be powered on and available over their operating system's networking facilities.
Xircom, Inc., was an American computer networking hardware and mobile technology company. Headquartered in Thousand Oaks, California, Xircom was one of the first companies to develop network computing products for notebook computers. Products included computer memory cards, LAN adapters, modems, and remote access server products. The company's products enabled notebook users to share information over a network connection.
COM One group was a manufacturer best known for its computer network adapters. The company was co-founded in 1987 by Jacques Saubade and Michel Petit and was headquartered in France. The name comes from the company's focus on modems.
A telephony system based on host media processing (HMP) is one that uses a general-purpose computer to process a telephony call’s media stream rather than using digital signal processors (DSPs) to perform the task. When telephony call streams started to be digitized for time-division-multiplexed (TDM) transport, processing of the media stream, to enhance it in some way, became common. For example, digital echo cancellers were added to long-haul circuits, and transport channels were shaped to improve modem performance. Then, in the mid-‘80s, computer-based systems that implemented messaging, for example, used DSPs to compress the audio for storage, and fax servers used DSPs to implement fax modems.
Shiva Corporation was a company that specialized in computer networking and associated equipment, in particular remote access products. The company was founded in 1985, in Cambridge, Massachusetts, United States. Shiva was co-founded by Massachusetts Institute of Technology (MIT) graduates Frank Slaughter and by Daniel J. Schwinn, the current president and CEO of Avidyne Corporation.
CT Connect is a software product that allows computer applications to monitor and control telephone calls. This monitoring and control is called computer-telephone integration, or CTI. CT Connect implements CTI by providing server software that supports the CTI link protocols used by a range of telephone systems, and client software that provides an application programming interface (API) for telephony functions.
Dialogic Group, Inc., formerly Dialogic Corporation, was an American multinational technology company headquartered in Parsippany, New Jersey, United States.

Dialogic telephony cards was a line of PC expansion cards developed in the 1990s by Dialogic Inc., at the time Media & Signaling Division of Intel Corporation, for computer telephony applications. The cards were produced by Sangoma Technologies Corporation.
Cisco LAN2LAN Personal Office for ISDN', created by Cisco Systems, was an entry-level ISDN remote access solution intended to be used by remote teleworkers, small remote sites, and schools. Dial on demand was heavily featured, as the product was from an era where time online and data transfers were cost prohibitive.
Brooktrout Technology, Inc., later Brooktrout, Inc., was an American telecommunications company based in Boston, Massachusetts, and active from 1984 to 2005. The company was initially focused on the development of hardware and software to allow personal computers to act as fax machines, similar to GammaLink's GammaFax. The company later developed fax server hardware for local area networks before ultimately pursuing Voice over IP and videoconferencing products. In 2005, the company was acquired by EAS Group, who merged Brooktrout with another company of theirs to form Cantata Technology. Cantata was in turn acquired by Dialogic Group in 2007.
