摘要： A multi-unit test system performs automated and dynamically alterable, double-ended testing of telephone lines, whose service is provided on copper cable pairs. A prescribed set of (e.g., twelve) individual tests are executed either from a hand-held measurement unit, or by a central office-resident direct access test unit, or by a collaboration of the two. The hand-held measurement unit and the direct access test unit exchange FSK-based test control messages with one another that are effective to cause a selected electrical condition to be applied to a first portion of the wireline and to cause a prescribed electrical measurement to be made at a second portion of the wireline.

摘要： A two-ended, line-driving and receiving/tone signal analysis system performs line connection verification applying a low-distortion, low-amplitude test signal to one end of a cable pair under test and monitoring the response of a remote end wireline pair. Preferably the test signal frequency is on the order of 110 Hz, which avoids domestic and foreign AC power signal frequencies and is spectrally equidistant from their harmonics. It also avoids ringing frequencies for POTS lines, and remains safely below the 350 Hz lower limit of POTS and other telephone line system services. In response to application of the 110 Hz test signal to tip and ring segments of a wireline pair at one end of the cable bundle, the energy of the 110 Hz component, as well as that of two other ‘spectrally nearby’ (slightly higher at 112 Hz and slightly lower at 108 Hz), are measured at a tip and ring pair at the far end of the cable plant. If the magnitude of a Fourier component of the received 110 Hz test signal for a Fourier correlation operation cycle (FCOC) is more than a prescribed differential greater than the magnitudes of the two nearby frequencies, it is inferred that the remote tip and ring pair is the same wire pair as the wireline pair at the one end of the cable, thereby identifying the two ends of the same wireline pair.

摘要： A portable, hand-held ‘test tag’ device enables a test unit to conduct a wireline connection verification test, in order to determine connectivity of a subscriber metallic wireline pair from a point of access by the test unit to a ‘test tag’ point of entry location along the metallic wireline pair. The ‘test tag’ includes a controllable termination circuit and a port coupled to one or more lead connects, that enable a craftsperson to connect the test tag to the metallic wireline pair. The controllable termination circuit includes a prescribed resistance that is configured such that, for a first applied line voltage, the test unit will observe characteristics of the metallic line pair terminated with a low resistance termination, whereas for a second line voltage, the test unit will observe characteristics of the metallic line pair terminated with a high resistance termination.

摘要： A diode-configured power supply interface circuit prevents inadvertent miswiring of power supply leads to wrong polarity voltages of either primary or auxiliary DC supply voltages from triggering the operation of a circuit protection device installed in the power supply path of a telecommunication circuit. It also indicates whether the device's power terminals are properly connected to a power source, so that if inadvertently reversed, the wires can be properly reconnected, and thereby provide for delivery of power from either power source, as required.
