Testing Developmental EC Software for G.168

Overview

Auto EC Test Software (XX067) is an application used to perform echo cancellation compliance testing automatically per ITU G.168 specification. ITU G.168 spec refers to characteristics of Line Echo Cancellers (LEC). Line Echo Cancellers are either high density standalone devices, i.e. many T1s or E1s in a landline network. Or they may be embedded in Gateways (between an IP and TDM networks or between Wireless and TDM networks)

The AutoECTest Software (xx067) is intended to work with GL hardware (T1 or E1 dual cards) and the customers EC hardware. But it can also be used to test development EC software, that is, the customer's EC hardware is not required. In this case the AutoECtest software is used as depicted below

As depicted above, AutoECTest Software works with the EC Software as follows

AutoECTest Software provides the input files Rin and Sin(with echo) to the EC Software. This is done by providing the files in a specified directory.
The EC Software is expected to pick up these stimulus files (by frequently polling) and apply them to the EC in synchronous fashion.
The EC Software produces the output files Sout and possibly Rout and provides it to the AutoECTest software for analysis. In general AutoeCTest Software is polling for output files once it provides input files to the EC Software.
The AutoECTest performs a full analysis (with detailed displays) that results in a "Pass" or "Fail". Screen shots are provided below.
AutoECTest then generates the next set of input files for processing by the EC Software.
This process continues until all tests in the test configuration are completed.
