Test strategy for DSL broadband IP access services

Abstract

In this paper the test methodology has been expanded for evaluation of DSL broadband services. This is a new strategy for testing and considering different aspects of test. This strategy can precisely test various features of DSL broadband equipment and services which can be delivered by them in terms of different aspects of testing such as functionality, performance, conformance, etc. It was practically executed over a designed testbed in Iran Telecommunications Research Center (ITRC) where a lab named NGN Pilot exists. The introduced strategy has a hierarchical structure from the topmost level of testing including different categories to the bottommost level including detailed test topics and test cases. This paper elaborates how the strategy was designed and how it can be applied to a desired environment to compare different DSL scenarios with each other. The strategy can then be used by a service provider to help deciding which solutions can achieve the best outcome.

A Novel Probabilistic Approach for Analysis and Planning of Large Capillarity Broadband Networks Based on ADSL2+ Technology

“…In order to evaluate the triple play communication in a DSL network, a standard model must be used, such as the ones suggested by (Papagianni et al, 2009) (Kerpez & Kinney, 2008) and (Sadri et al, 2007) (Figure 1), which define the sequence of connected elements: The architecture to be used will include the following items: 1. xDSL Modems, including ADSL, ADSL2, ADSL2+; 2. DSLAM (Digital Subscriber Line Access Multiplexer); 3.…”
