Overview

The Universal HD T1/E1 is an enhanced PC-Based T1 and E1 solution that utilizes familiar computer user interfaces, to provide comprehensive and versatile T1 or E1 testing capability at a competitive price.

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 HD Universal T1 E1 Cards)

Main Features

It is introduced with the following enhancements:

  • Smaller Size – The boards are smaller, with dimensions are 4.2" x 7.1" vs. the older boards 4.2" x 9.2".
  • High Density and High Speed - The boards are significantly faster, and significantly more efficient than the older boards. The new boards use DMA and a 32-bit wide bus.
  • CPU Utilization - CPU utilization with the newer boards is negligible. For example, one can simulate echo on hundreds of timeslots by running simultaneously "delay/attenuate" on all 24 T1 ports on all timeslots. The new boards are compatible with dual processor motherboards and software that simulates dual processors (i.e. hyperthreading).
  • Universal boards have adjustable transmit clock frequency (+ / - 300ppm) for testing frequency lock sensitivity of T1 or E1 equipment.
  • Supports two new port modes: Cross-port through mode and Cross-port transmit mode
  • Features in-service monitoring and emulation of T1 and E1 circuit connections.
  • Provides out-of-service troubleshooting such as bit-error-rate testing, alarm monitoring, signaling bit manipulation and recording, DTMF/MF generation and detection, and Drop and Insert capabilities
  • T1 E1 Pulse Shape and Jitter Measurement Analysis
  • Voice Frequency (VF) Drop and Insert : Besides providing access to in-band PCM data, the T1 (E1) provides VF interface for monitoring and inserting audio with Drop and Insert. Users can connect to VF ports using 3.5mm unbalanced (or mono) audio cable, with standard 600 Ohms termination mode only.
  • VF Tx Gains for Universal T1 E1 analyzer ranges from -7.2 dB dB to +18.2 dB in 0.1dB steps, and VF Rx Gains for Universal T1 E1 analyzer ranges from -18.0 dB to +7.3 dB in 0.1 dB steps.
  • Software Selectable T1 or E1 interfacing along with Drop and Insert
  • Universal boards can be plugged into either a 5 V or 3.3 V PCI bus 
  • Monitor the T1/E1 line conditions such as frame errors, violations, alarms, frequency, power level, and clock (or frame/bit) slips. 
  • Routing and Bridging emulation over Multi T1/E1 WAN interfaces using MLPPP (Multi Link PPP) and MFR (Multi Link Frame relay) protocols
  • Support for all "basic applications" and "special applications"
  • Physical layer analysis includes ability to send alarms and errors via SNMP Traps
  • All protocol analyzers now include frame length in protocol statistics selection choice for data link layer
  • Comprehensive Analysis / Emulation of Voice, Digits, Tones, Fax, Modem, Raw Data, Protocol, Analog, Digital, Echo and Voice Quality testing
  • Provides convenient handset interface for voice over the T1 or E1 line.
  • Remote testing and monitoring can be done using simple script based or GUI based client software.
  • Precision Delay Measurement under basic software measures the Round trip Delay of a system. Round trip delay measurement is done by sending a BER pattern with the insertion of an erred bit and timing the reception of the erred bit. Measurement is precise and accurate to the microsecond level. A delay up to 8 seconds can be measured. The internal delay of the card is subtracted from the round trip delay.
  • Capable of simulating as well as decoding and demodulating fax calls over T1/E1 lines using Fax Simulator and FaxScan™
  • Windows® and Linux Drivers for Open Source Applications 
  • Supports both 32-bit and 64-bit Windows® operating system.

Loopback

Universal T1 E1 Cards 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.
