Press Release Summary = TiQoS.InternetAccess ensures high quality of service for
Internet service providers and carriers

Press Release Body = Ebermannstadt, Germany - August 16, 2007. Vierling introduces
the test application TiQoS.InternetAccess as a new module for its proven TiQoS test
platform. TiQoS stands for "Testing in Quality of Service". TiQoS.InternetAccess
allows Internet providers and carriers to objectively assess the quality of the
Internet access and services they are providing based on defined measurement
parameters. The application also allows its users to quickly respond to quality
deteriorations no matter whether their customers use DSL, ISDN or analog equipment
to access the Internet.

Quality tests from the customer's perspective
The TiQoS.InternetAccess test application assesses the quality of Internet access
from an end-user perspective. How long does it take to set up a connection? Is the
promised bandwidth available? Are downloads working without any errors? Quality
criteria of this sort have a critical influence on customer satisfaction. Service
providers can use TiQoS.InternetAccess to continuously monitor the quality of their
services and document this information vis-à-vis their customers. "End-to-end
measurements with TiQoS.InternetAccess are useful for simulating real-world customer
behavior while assessing the service quality in an objective and
non-provider-dependent manner", according to Bernhard Steger, Director Business
Development at Vierling. "Besides service providers, we also have carriers using
TiQoS.InternetAccess to verify their network performance."


Scalable, non-network-dependent system
The test setup for TiQoS.InternetAccess involves remote test units (RTUs) that are
connected to the Internet like end users via a DSL, ISDN or analog modem. The system
also includes a TiQoS control center (TCC) and web servers that host different files
for Internet performance tests. The RTUs establish connections to the web servers to
download data and then assess quality parameters such as the time needed to
establish a connection, the DNS resolution time and the available bandwidth. Data is
downloaded via an Internet browser (http) or using the file transfer protocol (FTP).
TiQoS.InternetAccess also supports VDSL.

A proven test platform
TiQoS from Vierling is a proven modular test platform for performing active quality
tests from the customer's point of view. The TiQoS.VoIP application module simulates
IP subscribers and monitors the quality of IP-based voice services in next
generation networks (NGNs). TiQoS.VoIP determines defined parameters assessing voice
quality and network performance. The TiQoS.Voice application module allows QoS
measurements in classic public switched telephone networks (PSTNs). This application
for example produces mean opinion score (MOS) values (according to standards
P.800 / P.862) for the voice quality. TiQoS.Voice measures various additional
parameters related to switching and signal transmission. Customers who are already
using TiQoS can add the TiQoS.InternetAccess application module to their existing
system.
