Applications Description of Enhancements / Bug Fixes

T1 E1 Analyzer Software


  • Migration of Oscilloscope application from Quinn-Curtis to Codejock toolkit
  • tProbe, USB T1/E1, Express, tScan, Octal, and tProbe/USB Lite Analyzer installations, can now be invoked in User and Admin modes.
  • Single wrapper installer is provided to install T1/E1 Analyzer 64-bit and 32-bit installations.
  • Enhanced BERT: When clicked on graph Y-axis plotted points, user can see the X and Y values in a read only edit box on top.
  • MC-BERT – Supports Tx mode and error insertion option; improved automatic column resizing, optimized GUI usage.
  • T1E1 Development Application Toolkit – Examples folder updated with more information; Support for 64-bit dlls for GLcomInterface included.
  • Active Speech Level application - Allows viewing of the log file while the application is running; The log file is now updated after every write, so real-time users can see updates as they occur.
  • Active Voice Level GUI module – The log file is now updated after every write, so real-time users can see updates as they occur.
  • Default messaging version in WCS Server is now set to GLMSG_VERSION4 - By default when WCS server and WCS client GUI comes up it does not display any version choice, it's always v4 binary.  To enable GUI in both WCS client and WCS server we provide a wile ‘WcsVersion.ba34’ in the directory WCS client and server. If users rename this file to ‘’ they will trigger display of all selections of GUI controls (binary/ascii v3/v4) visible to user.
  • tProbe T1/E1, and USB T1/E1 Analyzer are now supported on USB 3.0 ports
  • All hardware card types have persistent port numbering now. Before if system crashes, reboots, USB ports reconnected, cards move in slots ports where reordered. Now ports are always ordered in the ascending order of corresponding board serial numbers.
  • T1/E1 Analyzer now links with Remote Desktop Services API via the Wtsapi32.lib library
  • The Oscilloscope and Spectral Display modules now include a method that checks the Current Session ID against the Console Session ID to determine whether the session is local or remote via RDT.  Local sessions operate as they always have.
  • SS1 Analyzer ported to 64-bit
  • Includes HDL File Conversion launcher

tProbe FPGA

  • A FPGA file (usbng_app3.bit) added for HW version 3 boards.  These changes affect the VF section which will require software gain changes for the VF Drop section
  • Updated VF level to 150 ῼ in FPGA


  • Default Configuration File – Modified Register 36h to 00H to transmit E1 national bits

Bug Fixes

Protocol Analyzers

New application

DDS Protocol Analyzer
Digital Data Service (DDS) Protocol Analyzer allows to capture and analyzer digital data at rates of 2.4kbps, 4.8kbps, 9.6kbps, 19.2kbps, 38.4kbps, 56kbps, 64kbps, N x 56kbps or N x 64kbps.The circuit can be in multiples of 56kbps or 64kbps (4 X 64kbps).


  • Protocol Analyzers decode DLLs corrected to support multi-threaded offline filters and joining of periodically saved files. This also improves filtering performance.
  • Displaying license library version in protocol analyzers.
  • T1E1 TRAU PDA now supports Active Calls Graph window
  • HDLC Tx Rx - Random Variable Frame Length Bucket option has been added to allow users to generate random frames of varying length values. Frames with different frame length values can be defined by distributing the total frames probability to 100%.  For example, you can choose to define 50% of frames to be generated with the frame length between 10 – 20, rest 50% of frames to be generated with the frame length between 60-70. New submenu item ‘Join Multiple Files’ used with periodic file saving feature allows to merge multiple trace files and open in offline mode for analysis. This feature also works for the captured trace files saved with filters enabled.
  • ISDN Analyzer - Support for ARINC746 decode is now included
  • ATM Capture - Network, Bit inversion and Octet Bit Reversion port selection to get clear view for all ports.
  • Protocol Identifier and Classifier - Added support to display only specific files while browsing
  • Suitable warning messages are now provided while exiting protocol analyzer when capturing (real-time) in progress
  • PPP Analyzer: Reassembled packets are now decoded
  • Certain settings were required to properly decode the example trace files in offline mode. To help users know these settings, a Help note (ReadMe.txt) is included for Offline and Realtime PPP Analyzer (T1E1).
  • TRAU offline traces corrected for compatibility issue. Updated *.hdltraces are placed in the T1E1 installation directory “C:\Program Files\GL Communications Inc\Octal Xpress T1 or E1 Analyzer\TRAU”

Bug Fixes

  • Receive Counts were not updating for AAL2 Type –this issue has now been fixed
  • Alarms are captured in Frame Relay Analyzer
  • Corrected GUI glitch when closing protocol analyzer PROT and GUI options. Losing focus going into background.

Octal T1 Analyzer (EMS)

Enhancements for Octal T1 Analyzer for EMS

  • A push-to-talk option was added to the Round-Trip Delay (RTD) measurement procedure.  Controls were added to allow the user to select this option and the RTD measurement code was updated to accommodate this measurement feature.
  • Files needed to support this option were added to the EMS Files subfolder.
  • During RTD delay measurements, an idle segment is transmitted at the beginning of file transmission to allow time for the channel under test to stabilize.  This stabilization interval was reduced from 8 seconds to 2.5 seconds.
  • The “Done” button was removed from the RTD Measurement (“Circuit Delay Test”) dialog.  This button was found to be awkward and frequently pressed inadvertently in practice.  Users now exit this dialog using the “X” button in the title bar.
