Abstract
Abstract A multiline telephone test receptacle for allowing testing of more than one telephone line connected to the receptacle in a convenient manner, for example, with a single line telephone set, without requiring special connections. In one embodiment, a movable member having an opening which is positionable in two positions over a telephone jack cavity allows contacts of a telephone plug to engage different ones of the telephone lines connected to the jack in the two positions, thus providing a convenient means for testing the two lines. In another embodiment, the contacts of the telephone jack cavity are disposed on a movable member and the opening is fixed. The telephone test receptacle can be expanded to allow testing of more than two lines.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
161 words
A multiline test receptacle comprising: receptacle means defining a cavity for receiving a plug means, said receptacle means having a plurality of contact means positioned within the cavity adapted to be connected to a plurality of transmission lines; and movable means defining an opening disposed over said receptacle means, said movable means being positionable in at least two positions so that said opening is disposed in at least two different alignments with said cavity, whereby engagement of selected ones of the contact means of the receptacle means with selected ones of contact means of the plug means upon insertion of the plug means through the opening of the movable means and into the cavity of the receptacle means is provided in said at least two positions, thereby allowing testing of a first of said transmission lines in a first position of said movable means and testing of a second of said transmission lines in a second position of said movable means.
Claim 2
Dependent Claim
161 words
A multiline test receptacle comprising: receptacle means defining a cavity for receiving a plug means, said receptacle means having a plurality of contact means positioned within the cavity adapted to be connected to a plurality of transmission lines; and movable means defining an opening disposed over said receptacle means, said movable means being positionable in at least two positions so that said opening is disposed in at least two different alignments with said cavity, whereby engagement of selected ones of the contact means of the receptacle means with selected ones of contact means of the plug means upon insertion of the plug means through the opening of the movable means and into the cavity of the receptacle means is provided in said at least two positions, thereby allowing testing of a first of said transmission lines in a first position of said movable means and testing of a second of said transmission lines in a second position of said movable means.
Claim 3
Dependent Claim
