Unobtainable number

The simplest way to make a point-to-point call is to

press the call signaller button .

However, in some areas it cannot be guaranteed

that the call will be routed to the correct signaller.

In these areas, signal box phone number signs or

short code ‘12nn’ signs (see section 4.4) give you a

direct-dial number to the controlling signaller.

You can also look up the signaller in the menu

phonebook (see section 6.6.2)

The cab radio will sound a ringing tone and display

that a call is being made.

When the signaller answers the call, the display

changes to show the call is connected and who you

are connected to.

If the number called is not an available number,

then an ‘unobtainable’ tone will be played and

message is displayed.

If the number called is busy, you will hear a busy

tone instead of the ringing tone and the message

displayed.
