PSTN Products

GAO Tek provides a large selection of high quality and budget-friendly public switched telephone network devices. The public switched telephone networks (PSTN) are international telephone systems that deliver analog voice data using copper wires. PSTN were formerly known simply as the public telephone networks and also referred to as the plain old telephone systems (POTS). They consist of a collection of individual telephones that are hardwired to a public exchange. GAO Tek’s PSTN include xDSL testers, phone line testers, E1 testers, and PSTN analyzers.

Functions of PSTN

xDSL testers provide full testing and analysis of ADSL/ADSL2/ADSL2+ lines accurately and fast, covering physical layers, network layers, and application layers. They are ideal tools for installation, maintenance, troubleshooting of the xDSL network.

Phone line testers are designed for the detection of digital or analog phone systems and line polarity in a phone line. Whether you need to install your telecom systems, connect PC to telecom systems, or maintain your systems, GAO’s Tek testers will satisfy your requirements.
