GL Enhances T1 E1 Analyzer Products / Software

Welcome to our first newsletter of January 2012 covering latest applications, and enhancements introduced to our versatile T1 E1 Analyzer product line. The T1 E1 software has been enhanced, now Version 6.14.

New Applications Introduced:

  • Multi-Link Frame Relay Emulator - Frame Relay and Multi-Link Frame Relay can be emulated on up to 16 T1 E1 lines using GL's client-server based MFR Emulator GUI or command line scripts.
  • Inverse Multiplexing over ATM (IMA) Emulator - Inverse Multiplexing over ATM (IMA) can be emulated on up to 16 T1/E1 lines using GL's optional client-server based IMA Emulator software module.
  • Channel Associated Signaling (CAS) Emulator - GL's MAPS™ CAS (Channel Associated Signaling) Emulator is an advanced protocol simulator for simulating CAS signaling over TDM (T1 E1). MAPS™ CAS automates the testing procedure with the ready scripts on single, multiple, or all timeslots. Calls are established, once the signaling information such as the signaling bits, MF, DTMF, or tones are detected. All CAS protocols, including wink-start, loop-start, ground start, R1, MFC-R2, etc. are supported, including custom CAS protocols.
  • Mobile Application Part (MAP) Emulator - GL's MAPS™ MAP (Mobile Application Part) Emulator is an advanced protocol simulator to simulate MAP signaling over D & H interfaces in GSM/UMTS networks as defined by 3GPP standards.
  • Multi-Link Point-to-Point Protocol (MLPPP) Emulator - GL's MAPS™ MLPPP Emulator is an advanced protocol simulator for PPP and MLPPP simulation over TDM (T1 E1 lines). Ready scripts are capable of generating and receiving MC-MLPPP/PPP traffic (with or without impairments), perfect for automating the test and regression procedures.
  • Fax Decoder/Demodulator (FaxDD)
    • Fax decoder/demodulator, an optional module within VBA, can be used to decode both 2-wire and 4-wire voice band captures to produce the Fax TIF images and corresponding signaling information. Fax decoder/demodulator is also available through command line.
    • Another version of this application is, FaxDDT38, designed for decoding IP captures and is a command line or batch file based application. FaxDDT38 converts a PCAP file, the output of packet captures such as from GL's PacketScan™ or other third party IP capturing tools such as Wireshark, into TIFF-F files containing the fax image. It also provides analysis of T.38 packets, T.30 frames, and general call-flow indicators

Enhancements Introduced to the Existing Applications:

  • Call Capture and Analysis (CCA)
    • Call Capture Options, Enabling Call Summary Records in CCA provides an additional Call Master Record (*.cmr) file containing information regarding the master process. Cause values for ISDN messages are now be displayed for the following ISDN messages, "disconnect", "release complete", and "release"; cause values will be written to CSV file for use by Call Records
  • Call Data Records (CDR)
    • CDR can now generate both CSV report and ASCII report together. Previously, the two outputs were mutually exclusive.
    • CDR now analyzes CAS calls in order to pick up dialed digits and to generate call completion information
    • CDR now analyzes SIP calls and produces call records accordingly
    • The generated call records can be processed to Excel files and analyzed more comprehensively to get the calls of interest using a built-in tool included with the Excel application. The generated measurements along with the recorded voice files of a particular call are combined in the Excel allowing the users to do custom filtering based on any measurements (ASL, AF, % Digits, %Voice, Mid-call-digits,...) or signaling messages (ISDN signaling, CAS Signaling, Release Codes, Call Duration, Call Events,...). The voice files of a particular call from the filtered records can be downloaded or played back using third-party audio editing tools such as Goldwave®.
  • ISDN Analyzer
    • An additional standard of ISDN has been added to ISDN analyzer - National ISDN PRI SR 4994.
  • ATM Analyzer
    • ATM Capture Options have been updated to provide an option in Stream/Interface selection window to select the IMA frame size.
  • HDLC Analyzer
    • An additional standard of HDLC has been added to HDLC analyzer - X.25 and updates done in LAPB layer decode
  • Protocol Analyzers
    • Provided users more flexibility to monitor required protocol fields. Detail view displays decodes of a user-selected frame from the summary view, the contents of this view can also be copied to clipboard
    • Hex dump view displays raw frame data as hexadecimal and ASCII octet dump, the contents of this view can also be copied to clipboard
  • Error Insertion
    • Error insertions can be inserted at user-defined rates for Frame errors, BPV, Logic errors and CRC error types. Each error can be independently set at different rates.
  • Capture Dialed Digits
    • This module now provides the user with the option of turning on audio when in scan mode
  • T1 E1 MAPS™
    • Implementation of global script for MAPS™ (Pass through)
    • Calls/sec is included in statistics.
    • Profile contents tab is added in Call Generation and Call Reception windows to view the protocol field parameters during script execution.
    • Sending report to web is now supported through scripts.
    • MAPS-CLI implementation is included
  • Default Rx, Tx/Rx Settings Changes in Configuration
  • Pulse Mask
    • Graphs generated can be saved to a file, zoomed-in/zoomed-out, printed, and more. Pulse Mask Display - the time period for searching for an isolated pulse mask in T1 is now configurable, from (0 to 1000 ms)
  • Jitter Measurement
    • New property page displays raw counts of the reference clock per tick of T1 E1 clock, second property page displays the number of reference clock ticks per T1 E1 clock tick. CSV file and Graphs can be generated for further analysis
  • Windows Client Server (WCS) version - WCS server code launch pads are updated to recognize a default listener IP address
  • Selective Signaling 1 (SS1) Analyzer and SS1 Dialer
    • Includes the capability of reading an initialization file at launch time, which allows them to operate in conjunction with Simplified Audio Client (SAC) and its modules.

In addition to the above, there have been many minor modifications and bug fixes to the T1 E1 Software. For more details, please refer to the link what's new in the current version web page.
