Brief summary of new and enhanced applications introduced:

  1. Automated Record/Playback and Enhanced Tx/Rx File Utility
    These applications enhance recording and playback features by providing automation (scripting) capability. Other new features include automated transmission and capturing of T1/E1 streams. Sub-channel transmission feature has also been added for applications such as TRAU, ADPCM, and G.729 that use fractional timeslot capacity of T1 and E1.

  2. Real-Time Bit Map Application - Now available under Monitor menu
    This application permits a graphical view of complete multiframe as a real-time bitmap. The application renders a pixel map with 'zeros' represented by white dots and 'ones' represented by black dots. Click on the link Real-Time Bit Map to see a snapshot of this application

  3. Windows Client Server (WCS)
    This application has been enhanced with the addition of task operators for "active speech level", "noise level", "speech activity", and "echo canceller" measurement algorithms. A Remote Client application that permits remote measurements and alerts of all significant voiceband parameters of voice traffic carried on T1 and E1 lines will be soon released. Additional enhancements and bug fixes are addressed for this application.

  4. Call Capture Analysis (CCA)
    This application has been enhanced to support automatic digit parsing and analysis on CAS based signaling protocols. As a result calls are captured with "called" and "calling" numbers identified in the captured filenames. This application in conjunction with the Call Management Utility (CMU) provides a powerful real-time tool for monitoring calls as they happen, with powerful tools for filtering and sorting calls and call records. It also provides capability to actively listen to calls as they happen. Please visit these links for more information: and

  5. Digital Echo Canceller (DEC)
    This application has been enhanced such that impulse response parameters of a hybrid being monitored can be easily extracted and used to model the exact same hybrid in the Lab using the Delay/Attenuate software application. This is a very powerful tool for debugging field conditions in the lab.
