Network isolators work to remove this hazard, by electrically disconnecting medical devices from a network. Isolators may be used as network accessories, built into medical devices, or installed within a medical network system. Networks isolators should be installed as close as possible to the medical device in question.
Ethernet became much more attractive when it moved from co-axial cable to twisted pair and an "interconnected stars" cabling topology based on active hubs. Easier cabling, combined with the greater raw speed of Ethernet (10 Mbit/s versus 2.5 Mbit/s for ARCnet) helped to increase Ethernet's demand. As more companies entered the market, the price ...
A bypass switch (or bypass TAP) is a hardware device that provides a fail-safe access port for an in-line active security appliance such as an intrusion prevention system (IPS), next generation firewall (NGFW), etc. Active, in-line security appliances are single points of failure in live computer networks because if the appliance loses power, experiences a software failure, or is taken off ...
In electrical engineering, a disconnector, disconnect switch or isolator switch is a type of switching device with visible contacts, ...
Link protection is designed to safeguard networks from failure. Failures in high-speed networks have always been a concern of utmost importance. A single fiber cut can lead to heavy losses of traffic and protection-switching techniques have been used as the key source to ensure survivability in networks.
In telecommunications, a network interface device (NID; also known by several other names) is a device that serves as the demarcation point between the carrier's local loop and the customer's premises wiring. Outdoor telephone NIDs also provide the subscriber with access to the station wiring and serve as a convenient test point for ...
A Network Rail spokesperson told The Independent: “Running at stations is one of the biggest risks to passengers, particularly with luggage, so we need to do everything we can to avoid that.
Cisco Inter-Switch Link (ISL) is a Cisco proprietary link layer protocol that maintains VLAN information in Ethernet frames as traffic flows between switches and routers, or switches and switches. [1] ISL is Cisco's VLAN encapsulation protocol and is supported only on some Cisco equipment over the Fast and Gigabit Ethernet links.
