State Transition Diagram of the Loop 3 State
2.3.4.1.2
Reset, Pending Deactivation
State after reset or deactivation from the line interface by info 0. Note that no activation
from the terminal side is possible starting from this state. A ‘DI’-command has to be
issued to enter the state ’Deactivated’.
Deactivated
The line interface is deactivated and the IOM-2 interface is or will be deactivated.
Activation is possible from the line interface and from the IOM-2 interface.
Power-Up
The line interface is deactivated and the IOM-2 interface is activated, i.e. the clocks are
running.
Pending Activation
Upon the command Activation Request (AR) the SCOUT-DX transmits the 2-kHz info 1w
towards the network, waiting for info 2.
