|Simulating Gaussian Crosstalk for DSL Testing||Timothy R. Clark||
The presence of crosstalk is a major detriment to the performance of Digital Subscriber Line (DSL) transceivers. It is therefore important to test performance under a wide variety of crosstalk scenarios. This thesis presents the development of a crosstalk noise generation system as a tool for DSL performance testing. Where many commercially available solutions are limited to specific testing needs, the system presented here is universal and can simulate virtually any noise scenario conceivable for DSL deployment.

|SIP Trunk Interworking: How the SIP Forum is Improving Interoperability between SIP-PBXs and Service Providers||James Swan (UNH-IOL), John Berg (CableLabs), David Hancock (CableLabs)||
Interworking issues continue to be an obstacle to achieving scale on SIP Trunk deployments. Due to variances in the SIP profiles supported by different SIP Trunk products, Service Providers and vendors are forced to spend significant time and people resources to identify and resolve interworking issues for each new SIP-PBX/SSP-network combination. The SIP Forum has been actively working on multiple fronts to resolve this interworking roadblock, and to move the rollout of SIP Trunking service toward more of a plug-and-play deployment model.
This session provides a status update on two important SIP Forum initiatives in this area:
1. The SIPconnect 1.1 Recommendation: This recommendation defines a SIP profile for the SIP Trunk interface between a SIP-PBX and Service Provider network. It defines procedures to resolve common interworking issues at the SIP Trunk interface for capabilities such as security, PBX registration, and call features.
2. The SIPconnect 1.1 Interop and Compliance Program: The focus of this program is to encourage the adoption of SIPconnect 1.1 through a series on interop events, and ultimately to develop a rigorous test-platform-based compliance program that will enable vendors to indicate product compliance with SIPconnect 1.1.

|Software Defined Radio (SDR) Based Implementation of IEEE 802.11 WLAN Basedband Protocols||Shravan Surineni||
The IEEE 802.11 family of wireless LAN protocols defines multiple physical layers implementations of which direct sequence spread spectrum (DSSS, 802.11b) and orthogonal frequency division multiplexing (OFDM, 802.11a/g) are currently the most popular. Market pressures are forcing the convergence of multiple wireless protocols into the same access device, and shortened product design cycles dictate rapid prototyping of new or enhanced protocols. The computationally intensive signal processing algorithms and high data rates associated with these protocols necessitate dedicated hardware implementation of some portions of the signal processing chain, yet allocating separate hardware resources for each of the standards would make the "universal access device" bulky and inefficient. Re-using the same software-reconfigurable hardware to handle different processing algorithms would enable an efficient, flexible alternative to current prototyping and implementation methods. In this thesis, the feasibility of using Software Defined Radio architectures as a prototyping tool for wireless LAN baseband signal processor implementations is explored. Signal processing architectures and algorithms for DSSS and OFDM protocols were developed in the Simulink and Matlab environments, and were then translated to VHDL hardware descriptions. A reference design for a OFDM transmitter was synthesized for implementation on a Xilinx Virtex II FPGA, and functional and timing simulations verified the design correctness.

|Super Demo 2004||MFA and MSF||
SuperDemo 2004 was the product of a partnering of the Multiservice Switching Forum (MSF) with the MPLS & FR alliance. Eleven companies participated in expanded testing including advanced service provider applications. The collaboration of the MSF and the MFA took the meaning of success to another level in the industry. The Multi-Vendor MPLS infrastructure was constructed for stability and reliability. The Demonstration of VoIP services across this network clearly conveyed a feeling of resilience.

SuperDemo 2003 was the worlds most advanced and comprehensive live test of multiple MPLS services operating concurrently across a multi-vendor MPLS network. The MPLS/FR Alliance SuperDemo included 14 different companies showcasing MPLS services and features such as VPLS, ATM/FR/Ethernet over MPLS, BGP MPLS VPNs and Fast re-route.

|Testing Home Routers for World IPv6 Launch||Timothy Winters||
The University of New Hampshire InterOperability Laboratory (UNH-IOL) hosted its fourth IPv6 Customer Edge (CE) Router Interoperability Test Event the week of April 16 - April 20, 2012 at its 32,000+ square-foot facility in Durham, New Hampshire. The test event brought together both users and suppliers of CE routers, also known as home router equipment. The purpose of the test event was to gain a perspective on the current status of IPv6 interoperability against the Internet Engineering Task Force (IETF) Basic Requirements for IPv6 Customer Edge Routers and support the Internet Society (ISOC) World IPv6 Launch. The eight participating vendor companies tested a total of ten distinct home router implementations throughout the week using publicly routable IPv6 addresses. Participants included Broadcom, CHT-TL IPv6 Testing Lab, D-Link, NDM Systems, Motorola Mobility LLC, Netgear, Time Warner and ZyXEL.
