Gaithersburg, Maryland, USA - November 02, 2023 - GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their tProbe™ - T1 E1 VF Serial Data Analysis and Emulation hardware. Its compact design, portability, and remote accessibility features make it suitable for field testing, monitoring, and troubleshooting network conditions on legacy networks.

“GL's tProbe™ is a test and measurement device for T1 E1 networks. It is portable, remotely accessible and contains a vast collection of applications. The tProbe™ can monitor and emulate common voice protocols including ISDN, SS7, CAS, etc. The tProbe™ also includes optional boards such as Datacom (DCE or DTE) and FXO FXS ports. The FXO port on the tProbe™ can simulate a two-wire FXO device such as a telephone or a fax machine” said Vijay Kulkarni, CEO of GL Communications.

The tProbe™ Datacom Analyzer is designed for the installation, verification, and maintenance of data communication and telecom equipment. It offers a software-selectable interface for emulating DTE and DCE, as well as monitoring data communication lines for both synchronous (sync) and asynchronous (async) modes of operation.

GL's Windows Client/Server (WCS) software allows T1 E1 analysis and emulation cards with remote operation, automation, and multi-site connectivity capabilities. The supported client is Python, and it can run on various operating systems, including Unix, Linux, and Windows®.

Additionally, the, Windows/Linux Client (WLC) is a Command Line Interface application. It sends commands to T1 E1 WCS servers and shows the responses in Console, PowerShell, or Terminal Windows. WLC functions in both Windows and Linux. Furthermore, it can be utilized on any operating system through SSH or another remote access terminal. WLC is a portable library for communication between Windows®/Linux clients and WCS servers, ensuring compatibility.

The tProbe™ is controlled by a Windows® PC via a USB connection. Customers often request a complete solution in which the PC is included. GL offers the 1U Rackmount enclosure or a Probe unit, each with an embedded PC.
