The T279 Circuit Termination Set provides the termination and balance arrangements required for sectionalizing noise measurements on a circuit. It is designed to facilitate noise investigations by installers and repairmen. When it is necessary to make noise measurements on sections of a circuit to identify the section which may be introducing the noise, it is necessary to provide the proper termination of the section under test with an appropriate terminating resistor and a well balanced center tapped coil to provide means for maintaining the longitudinal circuit. The balance of the coil must be such that it will not contribute any unbalance to the circuit under test. The Model T279 includes a balanced center tapped coil, a terminating resistor, two pairs of clip leads labeled FIELD and CO, and binding post terminals labeled TO MEAS SET. A toggle switch selects the direction in which measurement is to be made, either toward CO or toward FIELD, as shown on the front panel schematic illustration. The balance coil is connected across the line in the direction of measurement, while the line in the opposite direction is shorted and connected to the coil center tap to maintain the longitudinal path. A binding post terminal labeled G provides a means for making an external connection to the coil center tap. This terminal should be left unconnected during most measurements. |

The T136 Basic Circuit Test Set is designed for use by the installlers and repairmen in conducting circuit transmission and noise measurements without using elaborate or expensive equipment. It allows for simple, easily read loop parameter measurements. The T136 provides a 600 µ AC impedance and a 430 µ DC impedance across Tip and Ring, insuring a precise termination for performance testing. These impedances are in compliance with EIA specification RS470. All operating functions are selected via single six position rotary switch. DIAL position allows for the external connection of a remote telephone handset directly to the line, by connecting to the square Dial Posts. The dialing and holding arrangement provides switching from DIAL to other functions without disconnecting the line. BATT-TEST enables the T136 to test and verify the conditions of the unit batteries. GND mA (on T136BGMZW only) connects the mA circuitry to Ring and Sleeve of the line under test, without the necessity of manually disconnecting the set from the line and connecting directly across these two points. |

The T304B/T305 Bond Current Meter/Probe is a light weight, rugged, easy to use test set that is designed to measure alternating currents from 10 mA to 100 A. When used with either a T305 or T272A Current Probe, the T304B will measure cable shield currents without disrupting or disconnecting cable shield connections. The T304B's bond checking feature allows immediate on-site bond condition assessments to be made. The T304B Current Meter is a battery powered test set designed to display the output of the T305 and T272A Current Probes. These probes connect to the T304B through dual banana jack connectors. The T304B features a seven position switch selecting current ranges of 100mA, 300mA, 1A, 3A, 10A, 30A and 100A. A battery test button allows instantaneous display of battery status. In addition to an on/ off switch, which is mechanically forced to the off position when the cover is closed, a switch selects use of either the T305 or T272 probes. The T304B is powered by four 9V batteries which will provide approximately 300 hours of normal (intermittent) operation. |

Wilcom T124 Cable Shield Splice Tester is an accurate measuring device which provides measurement of the conditions existing at cable shield splices, checks the integrity of ground connection, and checks the condition of capacitors across insulated splices. Two probes, capacitively coupled to the shield of the cable under test, are connected to very high-input impedance amplifiers contained in the probe assemblies. The outputs of the two amplifiers are fed through a cable to a balanced transformer circuit in a measuring set. The measuring set is connected to any stable ground. When the two probes are placed on the same section of cable, the two signals generate a very low level reading on the measuring set; this reading is taken as a reference. The probes are then placed across a splice. If the shield splice is good, the two probes pick up the same signal level, and the reading on the measuring set equals the reference previously measured. If the splice bonding is defective, a higher reading is observed on the meter. The difference between the reference reading and the reading across the splice is an indication of the nature of the fault. |

The T207 Longitudinal Balance Test Set is designed to measure the longitudinal balance of single-port or two-port circuits and devices. This test set permits evaluation of relays, feed coils, networks, long-line units, amplifiers and other equipment present on the typical communications circuit. These devices may have poor longitudinal balance and thus contribute to the susceptibleness of the facility. The measuring technique and circuit configuration conforms to the IEEE standard 455-1976 for Longitudinal Balance Measurements. Longitudinal balance measurements may be made at single frequencies in the range of 40 Hz to 4 kHz. Also, as an added feature of the Model T207, a figure of merit balance measurement may be made using a shaped waveform which is representative of a power induced noise spectral distribution. Single frequency measurements on circuits with balance approaching 80 dB can be made with a typical accuracy of ± 1 dB. |

The T240 Artificial Cable Kit is an advanced concept in artificial cable kit design providing line sections which closely represent actual telephone cable sections, and including facilities which simplify and expedite the analysis of fault conditions on a cable when used in conjunction with the Wilcom T195 Level Tracer. Switches are included for introducing conditions which normally would require the removal of modules from an artificial line and then reassembling the line. New features make it possible to set up conditions for analyzing the effects of split pairs, unbalanced grounded ringers, high series resistance unbalance, shunt capacitance unbalance, bridged taps, and the effect of missing or improperly connected load coils, and to estimate how many bridged ringers may be on a loop. Appropriate precision and compromise networks are provided for return loss and impedance measurements. All modules are enclosed in 2" X 2" X 3/4" aluminum cans and equipped with rugged connectors for insertion and receptacles on a plug-board panel. |

Wilcom introduces the industry’s only non-metallic, non-intrusive Digital Signal Identifier. Comfortable to hold and easy to use, the light, but rugged D550 Non-Intrusive Digital Signal Detector SHARK is a breakthrough in Digital Signal Identification on copper pair cables. It eliminates accidental downtime (and unnecessary repair calls) on active copper pair cables due to metallic access. With adjustable signal sensitivity the D550 SHARK can be used at any distance from the CO or repeaters. Wilcom’s SHARK provides a non-intrusive method of identifying digital signals in bundles of wire. Simply by touching the wire insulation with the probe, never causing damage to the wire, the SHARK gives both audio and visual indicationsof an active digital signal. The SHARK takes the guess work out of which wire to cut or splice. |

Wilcom introduces a revolutionary new design to provide non metallic, nonintrusive access to T1 carrier span lines for testing purposes. The D560 Non-intrusive Digital Clamp-on Probe provides a technician nonmetallic access to a T1 signal on insulated twisted pair without affecting the signal being monitored. When used with a T1 Test Set, the user can perform tests as though tied directly to the copper wires. Jack the bantam plug into any compatible T1 Test Set and clip the probe tip onto the twisted pair. The self powered unit operates as though jacked directly into the system with metallic connectors. |
