A method of routing a globally-dialed telephone number to a selected customer number including the steps of selecting a geographic country code having an associated international gateway provider and receiving a telephone call having a dial string including the geographic country code and at least one additional identifier number or set of numbers. Normally, such images suffer from poor visibility due to backscattering and signal attenuation. A selected area of the DUT is illuminating a while the DUT is receiving test signals causing certain of the active devices to modulate. The second latch circuit takes in and holds the first digital signal held at the first latch circuit. The IC further includes an electrically conductive line being directly above the first sourcedrain region, electrically coupled to the first and second electrically conductive line segments through a first via and a second via, respectively, resides in a second interconnect layer of the integrated circuit, and runs in the reference direction.
