Data Sheet
2.3.5.1.2 States
Reset, Pending Deactivation
State after reset or deactivation from the U
from the terminal side is possible starting from this state. A ‘DI’-command has to be
issued to enter the state ’Deactivated’.

running.
Pending Activation
Upon the command Activation Request (AR) the SCOUT-P(X) transmits the 2-kHz info
1w towards the network, waiting for info 2.
Level Detect
During the first period of receiving info 2 or under severe disturbances on the line the U
receiver recognizes the receipt of a signal but is not (yet) synchronized.

Activated
The U
procedure by transmission of info 3. All user channels are now conveyed transparently.
Analog Loop 3 Pending
Upon the C/l-command Activation Request Loop (ARL) the SCOUT-P(X) loops back the
transmitter to the receiver and activates by transmission of info 1. The receiver is not yet
synchronized.
Analog Loop 3 Synchronized
After synchronization the transmitter continues by transmitting info 3.
