GSM-R user procedures (cab radio Version 2)

registered with the GSM-R network at the changeover point so that it is on the signaller’s

fixed terminal list of trains and mobiles.

 When operating in an IVRS radio area, and where authorised, the GSM-R cab radio

can be used for communication in place of the IVRS handset.

When changing between radios, it is essential that the driver checks the operational status

of the radio.

It may be possible for you to receive calls on both radio systems, if they are switched on.

However, if for any reason you become confused about the information being received,

you must seek clarification, stopping your train immediately if necessary, for example,

emergency calls received on both radio systems.

 When changing from GSM-R if you do not intend to use GSM-R later in the journey,

you must de-register the cab radio from the network before losing network coverage

(see section 6.4).

4.3 Registration aliases

In places where there is no signal or where

there may be confusion over the number to

enter when registering the cab radio, an alias

plate will be provided, see Figure 6.

You must use the 3-digit number shown on

the alias plate and not the signal number at

these locations.

4.4 Areas not supported by signalling-system based call routing

At certain signals the GSM-R network may not

be able to automatically route calls from the

driver to the signaller who controls the area.

In these areas the driver must call the

signaller either by dialling the signaller’s GSM-

R phone number using the keypad, or by

using the phonebook. A sign (Figure 7) will

be provided, displaying the correct signaller’s

GSM-R phone number, to remind drivers

about this.
