Overview

GL's Dual T1 E1 Express (PCIe) Boards are high-density dual T1 or E1 boards with newer PCIe (x1) bus interface.  These cards are identical to the portable tProbe™ units, except for FXO FXS and Datacom functionality.

In addition to the other basic T1/E1 line signals monitoring applications, the Dual T1 E1 Express (PCIe) Boards also support enhanced VF drop and insert capabilities  with software selectable VF Tx and Rx impedances (135Ω, 150 Ω, 600 Ω, 900 Ω, or High), Pulse Mask Compliance Testing, Jitter Generation and Measurement applications.

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 Dual T1E1 Express (PCIe) Cards)

Loopback

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.
