Overview

Complex T1 E1 testing just got simpler with GL's portable USB based T1 E1 analyzer.

GL's USB based T1 E1 Analyzer is a compact, full featured, and complete BERT, voiceband, data, signaling, and protocol analyzer. The USB T1E1 analyzer is a USB-Based T1 and E1 solution provide comprehensive and versatile T1 or E1 testing capability.

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 Signaling 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 Portable USB T1 E1 Cards)

Features

It is introduced with the following enhancements

  • Lightweight (less than 2 lbs) and small footprint (5" x 4" x 1.5")
  • The unit's lightweight and small footprint make it easy to carry in the pouch of a Notebook PC making it perfect for air travel. Compatibility with any Notebook PC allows the software to be installed on many PCs - just ship the unit to the intended location and use an available PC.
  • Software Selectable T1 or E1 interfacing along with Drop and Insert
  • Two (2) port and four (4) port captures of T1 and E1 signals with one or two USB T1 E1 Analyzers connected to a single PC 
  • Portability: Converts a Notebook or Desktop PC into a powerful T1 E1 test instrument
  • USB 2.0 interface for complete access to T1 E1 rate signals 
  • 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 USB T1 E1 analyzer ranges from -7.2 dB dB to +18.2 dB in 0.1dB steps, and VF Rx Gains for USB T1 E1 analyzer ranges from -18.0 dB to +7.3 dB in 0.1 dB steps.
  • Monitor the T1/E1 line conditions such as frame errors, violations, alarms, frequency, power level, and clock (or frame/bit) slips.
  • 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
  • Remote access and scripting: Install the unit and walk away! Use remote or scripting software to control or monitor the unit from anywhere. Any remote software such as VNC or PC anywhere will work. Or, use our powerful scripting software to automate and remote all data acquisition and processing functions.
  • Call Recording, Generation, and Monitoring for hundreds to thousands of calls in one platform 
  • 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.
  • It can perform analysis and emulation of various signal types including voice, digits, and tones; various protocols including HDLC, ISDN, SS7, CAS, Frame Relay, GSM, GPRS, CDMA, and UMTS.
  • It is capable of T1 or E1 PCM signal visualization, capture, storage, analysis, and emulation. 
  • Routing and Bridging emulation over Multi T1/E1 WAN interfaces using MLPPP (Multi Link PPP) and MFR (Multi Link Frame relay) protocols
  • Automate the IVR testing process - call establishment and traffic generation / detection process through scripts
  • Monitoring IVR System for voice and data quality 
  • HDL File Conversion Utility

    This application converts a file from Ethereal format files (.PCAP, .CAP, and .PCAPNG) to GL proprietary file format (.HDL) and vice-versa. The application can automatically detect the format of the source PCAP file whether it is captured on Linux or Windows® and converts accordingly to HDL file. By converting the file to *.HDL format, the users can use the converted *.HDL files in T1 E1, T3 E3, LightSpeed1000™, or PacketScan™ applications to decode and analyze.
