Цепь 107 в соответствии со стандартом V.24
Цепь 107, в соответствии со стандартом V.24
Цепь 107, в соответствии со стандартом V.24 - название и назначение этой цепи описано в стандарте V.24 для DTE следующим образом:
“Data set ready.
Signals on this circuit indicate whether the DCE is ready to operate.
The ON condition, where circuit 142 is OFF or is not implemented, indicates that the signal converter or similar equipment is connected to the line and that the DCE is ready to exchange further control signals with the DTE to initiate transfer of data.
The ON condition, in conjunction with the ON condition of circuit 142, indicates that the DCE is prepared to exchange data signals with the DTE for maintenance test purposes.
The OFF condition, in conjunction with the ON condition on circuit 106, indicates that the DCE is ready to exchange data signals associated with the programming or control of serial automatic calling DCEs.
The OFF condition, in conjunction with the OFF condition on circuit 106, indicates:
1) that the DCE is not ready to operate in the data transfer phase;
2) that the DCE has detected a fault condition (which may be network or DCE dependent) which has lasted longer than some fixed period of time, such period of time being network dependent; or
3) in switched network operation, that the DCE has detected a disconnect indication from the remote station or from the network.
6 Recommendation V.24 (02/2000)
The OFF condition, in conjunction with the ON condition on circuit 142, indicates that the DCE is involved in tests from the network or remote station”.
Группа сигналов и направление этого сигнала относительно DCE следующие: управление, к DCE, вход.
Назначение цепи: Готов выставлять данные.
Сигналы этой цепи показывают готов, ли DTE к работе.
Состояние ON показывает, что DTE готов к работе.
