PSTN Network Analyzers
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. 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.
PSTN analyzers provide the function for testing G.SHDSL, HDSL, and IP across the Internet. They can be used wherever line quality testing is needed. Moreover, they can also be utilized to verify the quality of PCM 2Mbit and V/X streams with the ability to display the channels status, frame, and multi-frame alignment words, errors, and alarms. Some PSTN analyzers contain the function of installing and maintaining frame relay networks. Other PSTN analyzers allow users to perform an X.25/X.31 connection over D channel and verify the quality of the line, test the verification of audio channels quality, and verify the correct operation of the several supplementary services supplied by the provider, such as AOC, CF, CLI, 3PTY etc. With so many interfaces and clearly defined analysis and diagnostic capabilities, GAO Tek’s PSTN analyzers provide a complete solution for troubleshooting problems in a multi-skilled engineering environment.
GAO Tek’s PSTN analyzers feature several connectors such as RS232, DB-15, and RJ 45 for transferring and uploading data. They also include an LCD display which indicates valuable information about data, battery power levels, and modes. Some devices provide options for automatic access test or a manual test. Several PSTN analyzers include a protocol analyzer that allows the capture of the main communication protocols over single and multiple channels. The onboard decoding allows for the analysis of traces on the spot. The advanced analysis through the PC software1 issued with the devices can be used for more complex problems involving connection issues or e.g user’s Internet configuration settings.
PSTN analyzers are mainly used in applications such as the installation of digital telecom circuits and services, long-term network monitoring, maintenance and troubleshooting.
