When a signal indicating that the phone network is unavailable is received, the engaged
(busy) signal is transmitted down the line in place of the dialling tone.
If you lift the receiver when the PIN code has not been validated, a series of beeps is
superimposed over the dialling tone.
In every case, access to the emergency service is still possible.
