GSM-R user procedures (cab radio Version 2)
If your first attempt to register that led to a
‘duplicate’ used a ‘99x’ then advise the
signaller of this and the signaller will provide an
alternative ‘99x’ to use.
The signaller may be able to clarify that the PA is shown on the fixed terminal and will
therefore be able to call the PA.
9.3.4 Wrong train reporting number displayed
If the train TRN displayed on the cab radio is not correct, deregister this number and try
registering again, with the same code. If this still returns an incorrect TRN, you must
deregister the TRN and contact the signaller controlling the movement of your train for
advice.
If the correct TRN is not shown, you must contact the signaller to check that your TRN is
shown on the signaller's fixed terminal. If the signaller confirms the correct TRN is
displayed, you may treat the radio as being correctly registered.
If the correct train TRN is not shown on the signaller's fixed terminal, you must treat the
registration as failed.
9.3.5 Duplicate registration identity
If the registration code is already in use by another cab radio, the network will reject your
registration and the message ‘duplicate’ will appear on the display. After checking that you
have entered the correct seven digits, you must contact the signaller controlling the
movement. The signaller will instruct you to use a 99x wild card location code which
should enable you to register successfully.

You can contact the signaller by calling them using the cab radio. However, because
the radio is not registered, you will need to find the number in the phonebook (see
section 6.6.2) or dial the signaller’s full number or the 12nn short code, if you have
access to it.
The registration code with the new 99x location code included can be entered whilst you
are still involved in the call with the signaller.
Press the button again and enter the registration code by pressing the appropriate
number keys, the digits will appear on the display and the registration process will be
automatically completed, once the call to the signaller is terminated.
If registration is still not possible but the radio is otherwise functioning correctly you must
report the problem to the signaller and follow the instructions that the signaller gives you.
9.3.6 Pending registration (trying to register if there is no coverage)
If you need to register the cab radio in a GSM-R area at a time when coverage is not
available due to network problems, you can set up the cab radio with the registration code
and it will automatically start the registration process once coverage is re-gained.
However, you will need to use the wild card 99X location code in order for the registration
process to be successful when you get network coverage again. Using the signal identity
