TX916 -
Aegis Pty. Ltd.
The Loop a Line has been a Telstra standard for 20 years. It is probably the simplest time saving device available for contractors and technicians. Once fitted to the far end of a line you can switch between Open, Short, Connect, 600 ohm, and Tone modes allowing all installation and fault location to be performed from the one end without having to go back and forward from one end of the line to the other.

8455 -
Simpson Electric Company
Simpson?s Model 8455 Line Loop tester detects line shorts, opens and multiple ringers, DC voltages and loop resistance. It can measure DC voltage up to 100 volts and loop resistance to 2 megohms. A front panel ?reverse polarity? switch allows changing polarity positions quicker and easier than manually switching test leads when making line checks.

Teletech Pty. Ltd.
Cable pair tracing and a lot more, Loop-a-Line products can remotely control a far end device (the oscillator) for up to 20km of cable. Using a Loop-a-Line allows the linesman to remotely change the state of the oscillator to any of five different states. Therefore eliminating the need for multiple journeys along the cable path.

295B -
JSD TestPhone Ltd
The Testphone 295B is a test telephone designed for use on Public Switched Telephone Networks (PSTN). It is designed for use on both Dual-tone Multi-frequency (DTMF - tone dialling) and Loop Disconnect (LD - pulse dialling) lines. Fitted with an integral ADSL filter, the telephone will not cause interference when connected to ADSL/Broadband lines in either `on hook` or `off hook` mode.

HFDF -
National RF, Inc
National RF's Type HFDF active directional antenna system consists of a high gain RF amplifier coupled to a tunable Faraday shielded loop antenna. Several loop antenna assemblies are available to provide coverage of frequencies in the HF and low VHF spectrum. Due to the nature of a Faraday shielded loop, the antenna exhibits a sharp null through the diametric center of the loop. This null is used to determine the direction of incoming radio signals or to locate electrical noise being radiated from some source. The internal high gain amplifier is used to compensate for the inherent inefficiency of the actual loop at the operating frequency. Overall, the system dynamic response is about +6 dB as compared to the dynamic response of a dipole. To aid in the direction finding process on strong signals, an internal 30 DB attenuator is provided. As the loop antenna presents a bi-directional response, tri-angulation may be required to eliminate the ambiguous signal direction. The line of site of the incoming signal is determined by listening for a signal null on the receiver or by watching the receiver’s S-meter.

ETT 10 -
Elektronika
Maintenance statistics of telephone networkshave shown that for most of the failures, theexchange - line - subscriber (EXCH-LINE-TEL) sections are responsible. Accordingly, the first step of the troubleshooting procedure is to locate the breakdown spot, i.e. to find out whether thefailure source is within the exchange, the subscriber site or in the line (local loop). Thisproblem can be easily solved by theTelephone & Exchange Tester ETT 10, in most cases without requiring the technician to visit the subscriber or the junction boxes along the line.
