Typically, they were half duplex, meaning that they could not send and receive data at the same time.
12.
For backwards compatibility with Ethernet hubs, the standard requires the autonegotiating device to use half duplex in these conditions.
13.
He is prompted for his password, which will be echoed as the terminal is connected in half duplex mode with local echo.
14.
There were also IMTS handheld transceivers ( Yaesu's 1982 vintage Traveler ) that operated on 2-4 watts, and these were all half duplex.
15.
Therefore, the autonegotiating end of the connection uses half duplex while the non-negotiating peer is locked at full duplex, and this is a duplex mismatch.
16.
In practice the limit was lower as a scanner with more than 48 half duplex lines could not support any 9.6 kbit / s lines.
17.
In half duplex mode both lanes are used for the same direction of data transfer allowing a double data rate at the same clock speed.
18.
Microphone audio was keyed either manually or by VOX, but unlike ordinary half duplex two-way radio both sides could talk at the same time without mutual interference.
19.
This is because wifi is an inherently half duplex medium and therefore any wifi device functioning as a repeater must use the Store and forward method of communication.
20.
Systems using Frequency Division Duplexing ( FDD ) offer full duplex connections between base station and remote sites, and Time Division Duplex ( TDD ) systems offer half duplex connections.
