          educational technical seminars with industry
          experts, Angus Ma and Jim Anuskiewicz, discussing
          VoIP Test & Analysis and testing requirements for
          MPLS & IP Differentiated Services. Learn what is
          important to test, why and how to test, as well as
          key testing requirements and goals.

SPEAKERS: Angus Ma, AHM Technology Corporation, M.Eng, MBA
          "VoIPTest & Analysis" Seminar

          Mr. Ma will educate network equipment manufacturers,
          end-users and service providers on the need for
          Voice over IP (VoIP) test and analysis. Attendees
          will gain an understanding of VoIP technologies and
          protocols, the relationship between network
          performance and voice quality, and defining Quality
          of Service (QoS) for voice networks. Step-by-step
          examples will be provided for: Mean Opinion Score
          (MOS) and P.800, Perceptual Speed Quality
          Measurement (PSQM) and P.861, end-to-end testing,
          core network, VPN, signal, and load testing, as well
          as troubleshooting of VoIP networks.

          Jim Anuskiewicz, Adtech Systems, BSEE, MSEE
          "MPLS and IP DiffServ Testing Requirements" Seminar

          Mr. Anuskiewicz will present the guiding
          principles for Multiprotocol Label Switching
          (MPLS), including functionality, motivation and
          signaling protocols. Attendees will learn about
          the latest MPLS developments to enable scalable
          high-speed packet forwarding to support the
          demands placed on the Internet by the
          convergence of voice, video and data over IP
          Networks. Included in this discussion will be
          the status of MPLS standards, test methodology
          and an overview of MPLS applications. IP
          Differentiated Services (DiffServ) also will be
          covered, as IP DiffServ plays an increasing role
          in specifying QoS over existing networks. This
          seminar will offer the rationale for IP DiffServ
          including motivation, comparison with other
          applications and the pros and cons. For more
