GL Conveys the Availability of Fully Automated EC Compliance Testing Solutions Per ITU G.168


Gaithersburg, Maryland (PRWEB) January 03, 2012

Gaithersburg, Maryland, USA -January 02, 2012- GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today the availability of the Fully Automated Echo Compliance Testing Solutions per ITU G.168 software.

 

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, Auto EC Test Software 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).

 

He added, AutoECTest uses GLs T1 E1 hardware platforms and can be used in TDM, Wireless, and VoIP configurations. Some typical scenarios are discussed below:

 

Landline-to-Landline In such calling scenarios, two LECs are involved in each call. Each LEC cancels echo at its tail circuit. It is possible that the delay in each tail circuit could be as great as 128 ms.

 

Wireless to Landline Only one tail is involved in wireless to landline calls, and therefore only one LEC is required at the landline end.

 

VoIP to Landline Only one tail is involved in VoIP to landline calls. The LEC is usually in a Gateway.

 

Auto EC Test Viewer supplements AutoEC Test software using which the EC test results are analyzed and graphically viewed.

 

Mr.Kulkarni further added, The Auto EC Test Software uses GLs T1 E1 Analyzer products and the customers LEC hardware to perform Automated Echo Canceller testing in accordance with ITU-T Specifications G.168. In the last 10 to 12 years, ITU G.168 has under gone many revisions with greater and greater detail and specificity and it has been updated accordingly.

 

He further added, Rin and Sin files (stimulus and echo) are prepared and generated in real-time by Auto EC Test software in accordance with user inputs. There are two solutions for different scenarios. The first Solution uses WCS (Windows Client Server) software to transmit/receive files and to simulate the echoes in real time. The second solution is designed for special applications where the LEC is still in development form, i.e. software only. Also, no GL hardware is required, as everything is file based.
