GSM-R user procedures (cab radio Version 2)

5.2 GSM-R cab radio display-screen layouts

The cab radio display contains four lines each with 20 characters and has four different

screen layouts depending on how you are using the radio. The display modes are: normal

mode; shunting mode; menu layout; and list layout.

5.2.1 Normal-mode layout

The normal layout and associated fields are shown below (the dotted lines are only to

show the boundaries between the fields and you will not see these on the display).

Network Name Headcode

Status 1 Action

Call information

Status 4Status 3Status 2

 The ‘network name’ will display “GSM-R GB” once the radio has found coverage.

 The ‘headcode’ field will display the train’s TRN, (only after the radio has been

successfully registered).

 The ‘status 1’ field displays the status of an action or process such as a call, in other

words “Calling”, “Connected”, “Incoming” or “Terminating”.

 ‘Action’ identifies an action that the driver might need to carry out particularly during a

call, for example, “PTT” (press to talk).

 ‘Call information’ contains extra information relating to the current process, for

example, the identity of the person making an incoming call.

 ‘Status 2’ is used to provide information about a new incoming call when a call is

already in progress (in which case the field will take up the whole display line), or to

display information about the battery support.

 ‘Status 3’, is used to indicate incoming messages.

 ‘Status 4’ is used for reminders or displaced messages from the ‘call information’ and

‘status 1’ fields.

5.2.2 Menu display layout

When displaying a menu the screen will be arranged as shown below. A navigation cursor

will indicate the selected menu item and can be moved up and down the list using the

scroll buttons.
