Overview
AutoEC Test TDM-VoIP application is designed to work with the TDM and VoIP networks. It uses GL’s T1/E1 Analyzer on TDM side of the gateway and RTP Toolbox™ on IP side of the gateway to perform the G.168 compliance test. It tests EC conformance to the ITU-T Specifications, G.168 (01/2007), G.168 (08/2004), G.168 (06/2002), and G.168 (04/2000).
AutoEC Test application performs the following functions –
- Generates the Rin file and Sgen file (double talk files)
- Generates the script file for WCS echo path simulation
- Generates the script file for the RTP Toolbox server to transmit stimulus file and receive the Sout file
- Executes the batch file to perform the test
- Automatically analyzes the Sout file per G.168 specifications
Features
- MS-Windows OS (WIN 2000 or XP) with User-Friendly Graphical User Interface
- Compatible with GL's T1/E1 HD Cards / USB portable T1/E1 units and RTP Toolbox™ application
- Real-time as well as off-line analysis
- Simulates an actual echo loop using Windows Client Server (WCS)
- Auto analysis of the response according to G.168 (01/2007) requirement
- Auto or Manual control of the EC during testing
- Tabular Pass/Fail Results
- Simulation of echo path with various delay, attenuation, hybrid filters, noise level, and more
- Detailed graphical results for individual overall test
Operation
The following steps are required to set up the AutoEC Test TDM- VoIP software.
- Select T1 or E1 as TDM interface
- Configure the GL hardware –T1/E1 card
- Configure the client settings to connect to T1/E1 server and other processing options
- Specify the location of T1/E1 server application
- Setup ISDN Emulator to automatically answer calls from TDM side
- Configure the IP address of the RTP Toolbox, media gateway, and client settings to connect to RTP Toolbox server
- Specify the location of RTP Toolbox Server application
- Set up the operator and EC information
- Select the EC control option as either Auto or Manual
- Configure G.168 test parameters
- Run the test cases
- Display the Sout graphically after all the tests are performed
EC RS 232 Control Setup
EC Control Mode
- Zeroing the contents of the echo canceller's H-register
- Enabling and inhibiting echo canceller convergence
- Enabling and disabling the non-linear processor
- If the echo canceller has a comfort noise feature, enabling and disabling the comfort noise generator
The Auto EC control mode allows users to specify the commands required to control the operation of the echo canceller. Thus, the application automatically controls the operation of the EC through RS232 serial port, TTL control (optional feature) and Ethernet (optional) during each trial.
