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.
