E1 & T1, Data, DSL, Protocols, BER Analyzers
With 20 years of experience in the development and production of test instruments, GAOTek is proud to provide a large selection of PSTN analyzers that meet the requirements of technicians working in the telecom industry for sale to the United States, Canada and Globally. Public Switched Telephone Network (PSTN) was designed to ease the two-way communication between two points or two users. In the beginning, a direct connection between two points was very simple, however the cost was too high depending on the distance and geography. The network engineers revolutionized voice communications by creating PSTN which is still in use today.


GAOTek’s PSTN analyzers are lightweight, field-portable, and rugged test instruments that can be used in the installation, measurement, and maintenance of telecom networks.


The main focus is circuit-based, or connection-oriented and the systems designed for one universal service- Voice. This system allows the network operator to route and bill for the calls as each step of the call is identified and managed by the network and switching systems.
