Process of systematically testing a link by sending a signal partway down the link and returning it.
Directing signals back towards a source along a communications path.
A diagnostic test or test state in which the transmitted signal is returned to the sending device after passing through a communications link or network.
The shorting together of wires in a connector so that a signal sent along the wire returns to its place of origin.
Loopback is a call made to a remotely located videoconferencing equipment. The signal is sent from the near site to the far end site where it is looped back to the originating equipment. With this test the near end can see what it is sending.
A diagnostic test where a signal is transmitted over a communications link or network and then returned to the sending device. Loopbacks are used to make sure the video equipment is working properly and as a way to demonstrate videoconferencing.
A video connection that feeds all or some of the components of a video call back to the codec which made the call. A full network loopback will give a user a delayed feed of his/her video and audio.The delay is approximately 1/4 of a second, giving the effect of an echo on both video and audio. Full network loopbacks are a good way to test the integrity of your site's connection to the IVN. A bridge loopback will only feed a user his/her video back; there will be no audio from this type of loopback. The IVN maintains several full network loopbacks that you can use for testing purposes.
Directing signals back toward the transmitting terminal at some point along the communications path. Used as a method of troubleshooting.
A method of performing a diagnostic test on a network, by sending a signal around the network and back to the originating device.
A method of checking the accuracy of data transmission in which the transmitted data stream is returned, or looped back, to its source for comparison with the original data. Loopbacks can be performed on data in an analog or digital state.
A diagnostic test that returns the transmitted signal back to the sending device. The returned signal can then be compared to the transmitted one. The test number for profile 007 is 2062219111 and the test number for profile 009 is 2062219109. CU - See Multipoint Control Unit
A diagnostic test that returns the transmitted signal back to the sending device after it has passed through a network or across a particular link. The returned signal can then be compared to the transmitted one. The discrepancy between the two help to trace the fault. When trying to locate a faulty piece of equipment, loopbacks will be repeated, eliminating satisfactory machines until the problem is found.
Send the outgoing signals back to the receiving side for testing.
When distributed tests are run on a single system, it is called loopback testing. This is also known as closed loop testing.
A diagnostic procedure where data is sent to the device being tested, and the output of the device is fed directly back to its input, looped around, and the returning data is checked against that which was sent.
A type of diagnostic test in which the transmitted signal is returned to the sending device after passing through all or part of a communications link or network.
Type of diagnostic test in which the transmitted signal is returned to the sending device after passing through a data communications link or network. A test typically runs on a four-wire circuit. The two transmit leads are joined to the two receive leads. A signal is then applied around the loop. This allows a technician or built-in diagnostic circuit to compare the returned signal with the transmitted signal and get some sense of what's wrong. Loopbacks are often done by excluding one piece of equipment after another.
A program that sends packets to a remote host on the Internet and looks for replies; works by means of the echoing facility provided by the ICMP protocol and is a way to determine if an Internet host is reachable from your host. See also packet internet groper.
A loopback is a communications channel with only one endpoint. Any message transmitted through such a channel is immediately received by the selfsame channel.
