Newsletter: GL Announces All-in-One, Stand-Alone Probe for Voice, Data, and Video Testing

Welcome to another June 2015 issue of GL's Newsletter covering enhancements introduced to our versatile T1 E1 Analyzer product line - now Version 9.5.5.


Enhancements Introduced to the Existing T1 E1 Applications

Optional Applications Advantage

Many optional applications that were offered at an additional cost (license) earlier are now part of the basic software and are absolutely free.  This means, customers to get lot more value to their money spent on GL's T1E1 Analyzer purchase.The Below Important Optional Applications are Included with the basic software:

tScan16™ T1 E1 Boards

Significant changes are introduced to T1 Tx/Rx Configurations.  “Tx settings” are removed from the configuration window.

Dual PCIe T1 E1 Boards

The driver installation process is changed to resolve the installation issues on Windows® 8.1.

UDP Multi-Frame Streaming (UMS) Architecture

As an alternative to GL's API, the UDP Multi-frame Streaming (UMS) Architecture is implemented to extend the access to raw data on GL's T1 E1 interface. This new architecture provides very simple and cost effective application development solutions, wherein, the client applications can be developed in any language.

The data streams in T1 E1 are converted by the UDP server to UDP datagrams and streamed to specified UDP port.  At the receiving end the client applications can listen to UDP streams and convert the data packets back to T1 E1 frames.

Error Insertion Application

  • Significant changes introduced to options in Error Insertion Application to allow it to work consistently under the following scenarios: Cross port Tx, Framed, Cross port Normal, Framed  Cross port Tx, Unframed Cross port Normal, and Unframed
  • Added controls which monitor TS0 Pass Through
  • Auto Resync disabled when Error Insertion invoked in unframed mode with cross-port transmit or cross-port through mode enabled
  • Auto Resync enabled for all other modes when Error Insertion is started

Jitter Generation Application

Significant changes introduced to Jitter Generation:

  • The options now clearly identified as Jitter Mask Configuration and Jitter Sweep Configuration. The Jitter Mask Configuration provides actual masks from standards as preset values and the application also provides a "Custom Mask" option to edit the values per user requirements. Pre-configured masks available to the Jitter Sweep Configuration as well
  • Jitter Mask graph plotted with a thin dotted line and Jitter Sweep graph plotted with a thick solid line for better visibility
  • The frequency step size moved from the Jitter Mask configuration window to the Jitter Sweep Configuration window
  • In sweep mode, a Pause button added to pause and restart the sweep. (When the sweep is paused, the device still generates jitter -- hitting the button temporarily stops the sweep, not the jitter generation.)
  • The port on which the Jitter Generation to be performed should have its jitter attenuation filter set to Receive in the configuration. An error checking implemented to ensure the process

API

  • Implemented enhanced VF checking
  • Implemented enhanced VF functionality

  • BERT channel availability now rigorously checked and handled
  • Support for 16-bit 16Khz VF Operations

WCS Fax Simulator

  • Provides additional fax call flow messages
  • Provides statistics stating the quality of the call
  • FAX Session now enables user to choose separate timeslots for Transmission and Reception and it helps specially to support FAX on FXO FXS ports

WCS LAPD Server

  • A new command  implemented to get the Link Statistics
  • Some more counters included for the Link Statistics command
  • Performance improved

WCS HDLC Tx Rx

  • HDLC Tx Test modified for easy multiple port interface
  • New Commands added to the HDLC TxRx Server application to get the statistics of the link

  • Protocol Buffer Support for MAPS™ CLI - This feature implemented for a more efficient method of communication between MAPS™ CLI and different clients (TCL, MTC, Python…). ‘Protocol buffers' a flexible mechanism for defining data structures, similar to XML.  ‘Protocol buffers' used to generate data access classes that are much simpler to use programmatically, faster, and less ambiguous
Other enhancements Include:
  • Performance improvements - Code optimization (SetLevel in decode classes) performed to increase calls per second
  • Load External Dll in MAPS™ scripting enables the scope to all API's of that DLL.  For example, to implement Voice Quality Testing (VQT) functions within MAPS™, simply use Load External DLL to access all voice quality analysis commands
