Portable telephone set usable as a paging receiver for remote notification and response to calls and messages
First Claim
1. A portable radio telephone set comprising:
- a main wireless unit for transmitting and receiving call signals, said main wireless unit having a silent mode for selectively generating an alarm signal in response to receiving a preassigned call signal without generating a ringing tone; and
a pager subunit, remote from and coupled to said main wireless unit, for mutually communicating with said main wireless unit, said pager subunit receiving said alarm signal only when said main wireless unit is in the silent mode, to produce an indication at the subunit that the main wireless unit has received a preassigned call signal, and said pager subunit having a silent mode for producing a non-audible indication that the main wireless unit has received a preassigned call signal.

Abstract
A portable telephone set for transmitting and receiving signals has an alarm element for generating an alarm signal in response to a preassigned call signal. The alarm element can be selectively put into a silent mode without generation of a ringing tone. The telephone set comprises a main unit for transmitting and receiving the signals containing the call signal, and a subunit, remote from and coupled to the main unit either electronically or by a cable, for mutually communicating with the main unit. The subunit receives the alarm signal when the alarm element is in the silent mode and produces an indication at the subunit that the main unit has received a preassigned call signal. The subunit can also include means for sending commands to the main unit.
