Central Office Line Simulator
AI-7280
-
The AI-7280 is a highly flexible central office line simulator. It is designed primarily for the testing and verification of common terminal equipment, including standard telephones, Caller ID devices, SMS (Short Message Service) capable equipment, and any device using an analog Tip/Ring interface circuit. Supplied with the TRsSim software for Windows, it can analyze a telephone''s DTMF characteristics, pulse dialing and flash timing, generate various network tones and ringing patterns. Both Type I (on-hook) and Type II (off-hook) Caller ID is supported using either FSK or DTMF data transmission. As an optional component, the TRsSim software can perform SMS testing to either the ETSI protocol 1 or protocol 2 standards.

Air Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.
