DSL Deployment Workshop

Course Duration
5-day instructor-led training, 0900-1700
Course Instructor
The instructor has 18 years experience in designing, implementing and supporting converged data, voice and video networks. He is a featured presenter at many international conferences on the implementation of emerging technologies. He is a member of the DSL Forum and is active within the technical committee on VoIP and QoS for combined data, voice and video networks using ADSL, ADSL2, ADSL2+, ADSL4, VDSL and SHDSL access technologies. Within the DSL Forum several contributions have been made in th Architecture Working Group on QoS, CPE residential gateway (RG) equipment. Recent work at the ITU-T has focused on multi•-service platforms to implement Full Service Access Networks (FSAN) using Broadband Passive Optical Networks (BPON) and Gigabit PON (GPON) to create Fiber to the Premises (FTTP), Fiber to the Home (FTTH) networks. He participates on the service provider QoS settlements standardization process. He is a member of BICSI with a focus on high speed wiring with fiber and copper. He participates in the IEEE 802.3 study groups for Ethernet (including IEEE 802.3af for Power over Ethernet) and high speed Ethernet. He is an active member of the IETF (Internet Engineering Task Force) with working group participation with Session Initiation Protocol (SIP) and secure SIP to implement next generation hosted voice services using VoIP phone sets, voice gateways, and Integrated Access Devices (IAD). He participates in SIP Interoperability Test (SIP-IT) events.
