In a mobile telephone terminal, a vibrator is provided for producing
tactile sensation. In response to an input signal from a manual input
device during a speech mode of communication, a vibrator-on signal is
transmitted from the mobile telephone terminal to a mobile network. In
response to the vibrator-on signal from the network, the vibrator is
activated to produce tactile sensation. Preferably, a table memory is
provided for mapping a number of signaling codes to a number of
corresponding items of information. One of the signaling codes is selected
in response to an input signal from the manual input device and the
vibrator-on signal is transmitted to the network for indicating the
selected signal code.
