A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment ...
IrDA data communications operate in half-duplex mode because while transmitting, a device's receiver is blinded by the light of its own transmitter, and thus full-duplex communication is not feasible. The two devices that communicate simulate full-duplex communication by quickly turning the link around.
This JREAP application presumes full-duplex data-transparent communication media. JREAP C JREAP C makes use of the Internet Protocol (IP) in conjunction with either the User Datagram Protocol (UDP) or Transmission Control Protocol (TCP). The IP suite is a standard set of protocols that is deployed worldwide in commercial as well as military ...
In the Ethernet protocol, when a communication collision happens (when two users of the medium try to send at the same time), each user waits for a random period of time before re-accessing the link. However, a user will wait ("back off") for a random amount of time proportional to the number of times it has successively tried to access the link.
The protocol is an enhancement to the Multi-Link Trunking (MLT) protocol. DMLT allows the ports in a trunk (MLT) to span multiple units of a stack of switches or to span multiple cards in a chassis, preventing network outages when one switch in a stack fails or a card in a chassis fails.
V.22 is an ITU-T recommendation for full-duplex communication between two analogue dial-up modems using PSK modulation at 600 baud to carry data at 1200 or 600 bit/s. It is a variant of the Bell 212A modulation format. V.22bis is an ITU-T recommendation extending V.22 with a faster rate using QAM at 600 baud to carry digital data at 2400 or ...
It features multiple (commonly dual) redundant balanced line physical layers, a (differential) network interface, time-division multiplexing, half-duplex command/response protocol, and can handle up to 31 Remote Terminals (devices); 32 is typically designated for broadcast messages.
An optical multiplexer is used to split transmit and receive signals into different wavelengths (1530 and 1310 nm) allowing them to share the same fiber. Supports up to 10 km, full-duplex only. [13] 100BASE-LX10: 802.3ah-2004 (58) ST, SC, LC: 100 Mbit/s Ethernet up to 10 km over a pair of single-mode fibers, using 1310 wavelength, full-duplex ...
