# Stand By (SB)

SB.1Stand By (SB) cannot be selected by the Driver. SB mode the mode in which ETCS on-board equipment awakes in.

In SB mode the driver has no responsibility for train movements.

Data for the mission is collected in SB mode. The driver can enter/revalidate the following data:

1. Driver ID,
2. Train Running Number,
3. Virtual Balise Cover,
4. ERTMS/ETCS level,
5. Radio information,
6. Train Data.

SB.2The Start of Mission (SoM) procedure is initiated when the mode is Stand-By, the desk is open and no communication session is established or is being established.

The driver may have to start a mission:

1. Once the train is awake, OR
2. Once Shunting movements are finished, OR
3. Once a mission is ended, OR
4. Once a slave engine becomes a leading engine.

The SoM procedure is not always the same, since some data may already be stored, depending on the previous situation.

As soon as a transition to any mode other than SB is achieved or the desk is closed, the SoM procedure ends.

SB.RAD-[L23].8Once the RBC ID/phone number are entered or re-entered/revalidated, the Main window is presented to the driver with all the buttons disabled. The Hour Glass symbol (ST05) is displayed to indicate that the ETCS on-board awaits an answer from the RBC.

SB.RAD-[L23].9Whether the RBC session opening is successful or not, the driver shall not act until the Main window is reached again with all the button enabled. The text message “Trackside not compatible” is displayed for 30 seconds if the opening of the session is not successful.
The train cannot continue in ETCS when this text message appears. The steps that the driver shall follow in this situation are included in the DEG.VER Managing incompatibility system version (VER) section.

SB.RAD-[B32.L23].7The driver also can re-enter or re-validate the Radio data from the Main window once it is reached during the Start of Mission procedure.

The steps to re-enter or re-validate the Radio information data from the Main window are explicated in the OTH.ODA.RAD Change of Radio information (RAD) section.

SB.RAD-[B32.L0N1].1When selecting the ERTMS/ETCS levels NTC, 0 or 1, the driver can re-enter or re-validate the Radio data from the Main window. The Radio Data button on the Main window is enabled and the driver could introduce the Radio Network ID when:

1. the train is at standstill AND
2. the Driver ID is valid AND
3. the mode is SB/FS/LA/SR/OS/NL/PT/UN/SN AND
4. the ERTMS level is valid.

To introduce other Radio Information, the level entered or revalidated has to be 2 or 3.

SB.RAD-[L23].10In addition to the previous cases, the driver can also re-enter the radio information through the Level button of the Main window. Once the ERTMS/ETCS level is re-entered or revalidated and the ERTMS/ETCS level is 2 or 3, the option to enter or revalidate the radio data is presented to the driver.

SB.RAD-[L23].11During the radio data entry process, the driver is presented with several messages which shall be read and considered.

SB.RAD-[L23].12The text message “Radio network registration failed” is displayed to indicate during the start of mission procedure that:

1. The list of available and allowed Radio Networks is empty and no Radio network ID can be entered.
2. A sufficient time has elapsed since the latest Radio Network registration order was sent to a Mobile Terminal.

In the case that this text message is displayed, the driver shall enter the Radio Network identification.

SB.RAD-[L23].13The text message “Trackside not compatible” is displayed to indicate that:

1. The opening of the session with the RBC has failed due to no compatible version.

The train cannot continue in ETCS when this text message appears. The steps that the driver shall follow in this situation are included in the DEG.VER Managing incompatibility system version (VER) section.

SB.RAD-[L23.N].1The text message “Train is rejected” is displayed to indicate that a train has been rejected. In this situation, the driver shall inform the signaller about the situation (train rejected) and the driver shall apply non-harmonised rules.
