Overview

GL's new tProbe™ is an enhanced version of our popular USB based T1 E1 VF Analyzer / Emulator. This hardware incorporates all the features of the previous analyzer such as portability, USB interface, remote accessibility, scripting, and a vast collection of optional applications.

GL's tProbe™ also includes ability to add optional boards such as the Datacom Analyzer, and FXO-FXS Simulation boards. The FXO port on tProbe™ allows to simulate a two-wire FXO device such as a telephone or a fax machine. This feature allows you to capture and analyze data from a two-wire telephone line, as well as to generate and transmit analog data onto that two-wire line.

Similarly, the FXS port on tProbe™ emulates a two-wire FXS service such as a telephone wall jack.  This feature allows you to interface with an FXO device such as a telephone.  Server commands allow you to provide standard FXS features such as monitoring for the off-hook line, sending ring signals, and providing dial tone.

GL's tProbe™ Datacom Analyzer is designed for the service installation, verification, and maintenance of Datacom and telecom equipments. It provides a software selectable interface to emulate DTE, DCE and monitor the Datacom lines for both synchronous (sync), and asynchronous (async) modes of operation.

Increased Performance with 64-bit Support

GL’s T1/E1 analyzers supports both 32-bit and 64-bit applications. 64-bit support improves the performance of Protocol Analysers viz., ISDN, ISUP, GSM and allow users to monitor Hundreds to Thousands of Signalling Links simultaneously and continuously. Also, provides improved processing and response time for Statistics, Call Data Records, Search and other such functions.

Enhanced CCA application allows better processing and response time for multiple instances of CCA applications for long run tests. Similarly, all basic Intrusive and Non Intrusive applications such as BERT, Monitoring Applications, Oscilloscope, Spectral Display etc provide better processing and response time for multiple instances of monitoring and simulations windows.

MAPS™ Protocol Emulators are enhanced to provide improved performance for load generation and simulation of Protocols on 16 T1/E1 ports simultaneously.

Client Server commands support Thousands of Tasks simultaneously with number of successful thread creation. This helps to run Tx Rx File, Tx and Rx Tone and Tx Rx Digits on 24/31 Timeslots * 8 Ports * n (where n is the number of tProbe™ T1 E1 Cards)

Loopback

tProbe™ supports Normal (no cross-port), Cross-port Through, and Cross-port Transmit loopbacks.

Cross-port Through Loopback

Cross-port Through Loopback

This mode is similar to the standard Outward Loopback except that the signal received on Card 1 (Port 1) is transmitted out onto Card 2 (Port 2). Likewise the signal received on Card 2 (Port 2) is transmitted out onto Card 1 (Port 1). This feature allows monitoring T1/E1 lines in-line while still being protected from loss of power to the board. This mode is effected entirely thru relays and eliminates complex cabling.

   
   
Cross-port Transmit Mode Loopback

Cross-port Transmit Mode Loopback

In this mode, the data that would normally be transmitted on Card 1 (Port 1) is diverted and transmitted on Card 2 (Port 2) and the data that would normally be transmitted on Card 2 (Port 2) is diverted and transmitted on Card 1 (Port 1). The receive paths are completely unaffected. This mode is particularly useful for Drop and Insert and Error Injection applications in which the board analyzes and may insert traffic running between two pieces of T1/E1 equipment. This feature also eliminates complex cabling.
