Abstract
Abstract A control apparatus for remotely controlling the operation of a telephone hand set when a hand set is remotely located from its associated base. The apparatus includes a housing having first and second connectors mounted thereon. The connectors respectively receive mating plug and are insertable into the hand set connector to connect the housing between the hand set/receiver cord and the plug in connector in the telephone hand set. A switch is mounted on the housing and includes a switchable contact connected in the ringing circuit of the telephone network for opening and closing the circuit upon each depression of the switch. In another embodiment, the switch is mounted directly in the telephone hand set.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
143 words
An apparatus for remote control of a telephone having a hand set and a base connected by a conductor by a pair of mating plug-in connectors and including at least a dial tone circuit comprising: a hollow housing; a first connector removably engageable with the plug-in connector on the telephone conductor from the hand set; a second connector removably insertable into the plug-in connector in the base; the housing being located in close proximity with the hand set; and switch means, mounted on the housing, for selectively opening and closing the dial tone circuit when the hand set is located remote and separate from the base, the switch means including a contact switchable between first and second positions; the contact being connected in the dial tone circuit for selectively opening and closing the dial tone circuit upon successive activation of the switch means.
