Telos Systems
Telos Systems—part of the Telos Alliance—was founded in 1985 by Steve Church, a talk show radio host and engineer who was dissatisfied with the poor quality of the on-air telephone calls on his shows. He was also an Engineer determined to do something about it. The resulting Telos 10 telephone interface system was a great success, inspiring Steve to build a business to make and sell the systems. Telos Systems has since become the industry leader in broadcast telephone systems and IP and ISDN codecs. The breakthrough Telos Zephyr audio codec, for example, is one of the most successful digital broadcast products in history, with more than 21,000 in use worldwide. Telos telephone hybrids and on-air talk show systems set the performance benchmark for the industry, and we continue to pioneer groundbreaking technology that pushes boundaries and gives broadcasters the telephony solutions they need for reliability, efficiency, and the best possible sound quality.

Open Circuit Locator
A994
The A994 is an open circuit locator for electric and telephone cables wind on the reel; it gives the position of the fault from the inside or outside end of the cable, in percentage to the total cable length. The instrument measures the ratio of the capacitances of the two sections of failed conductor using two high precision i/v converters. The advantage of this method is due to the fact that the measurement error depends almost exclusively on the dimensional inhomogeneity of the cable. The A994 has the unique feature to permit the location of fault in cables with all broken wires. This instrument locates breaks in cables with a total capacity between 2 nF and 5 uF. The distance to fault is displayed on a large LCD display.
