Loopback (also written loop-back) is the routing of electronic signals or digital data streams back to their source without intentional processing or modification. It is primarily a means of testing the communications infrastructure. Loopback can take the form of communication channels with only one communication endpoint.
NAT hairpinning, also known as NAT loopback or NAT reflection, [27] is a feature in many consumer routers [28] where a machine on the LAN is able to access another machine on the LAN via the external IP address of the LAN/router (with port forwarding set up on the router to direct requests to the appropriate machine on the LAN).
If supported, the DTE can signal the local DCE (the one it is connected to) to enter loopback mode by setting Local Loop (LL, pin 18) to ON, or the remote DCE (the one the local DCE is connected to) to enter loopback mode by setting Remote Loop (RL, pin 21) to ON. The latter tests the communications link, as well as both DCEs.
Sometimes, the loop device is erroneously referred to as loopback device, but this term is reserved for a networking device in operating systems. The concept of the loop device is distinct. In BSD-derived systems, such as NetBSD and OpenBSD , the loop device is called "virtual node device" or "vnd", and generally located at /dev/vnd0 , /dev ...
Another commonly used notation represents the mode as a (CPOL, CPHA) tuple; e.g., the value '(0, 1)' would indicate CPOL=0 and CPHA=1. In Full Duplex operation, the master device could transmit and receive with different modes. For instance, it could transmit in Mode 0 and be receiving in Mode 1 at the same time.
Founder mode is a way of running a company—the way a founder would run it—as distinct from manager mode, the way it would be run by “merely a professional manager.”
The telephone company usually has the ability to remotely activate loopback, without even needing personnel at the customer site. When looped back, the customer equipment is disconnected from the line. Additional smartjack diagnostic capabilities include alarm indication signal, which reports trouble at one end of the line to the far end. This ...
As bird flu cases continue to rise in the U.S., heavily impacting egg-laying flocks, so have the prices on cartons of fresh eggs due to dwindling supply. Egg prices are through the roof, and the U ...
