Abstract
Abstract A device for use in testing the wiring integrity and/or troubleshooting system faults in a modem and/or an associated telephone line which are coupled together through a modular plug coupled to the modem and a modular jack coupled to the telephone line. A first eight-contact modular jack adapted to receive the modular plug on the modem is mounted on one end of a box-shaped housing. A second eight-contact modular jack is mounted on the other end of the housing. The two modular jacks are electrically connected by a set of eight conductor elements, each conductor element connecting a contact on the first jack with a corresponding contact on the second jack. A test pin is coupled to each conductor element and projects upward from the housing. A set of three cables are also provided. Each cable has an eight-contact modular plug at one end for plugging into the second modular jack on the box device, the box along with the appropriate cable are connected in series between the modem and the telephone line and a meter or other piece of test equipment is connected to whichever test pins the user wishes to test.
