Any Occam product course.

Course Outline

This course is designed to be the Occam BLC customer, IPTV-specific follow up training to our 3-day TCPIP, Ethernet & Network Essentials course. Telecom service providers are commonly implementing IP television via a consortium of vendor products and technologies. These vendor products/applications include IPTV middleware servers, VOD (Video On Demand) servers, head end multicast IP MPEG rate shaping source devices, EAS (Emergency Alert Systems), Caller ID on the TV systems, encryption devices, multicast enabled routers and in some cases, web access and/or “walled garden” from the TV as well. All of these technologies, products and applications are integrated into a single IPTV service over ADSL and/or fiber circuits through your Occam BLC platform.

Students leave this class with a crystal clear, comprehensive understanding of IPTV technologies, protocols and message events. While the other IPTV product configurations will be covered generically, with common vendor-agnostic configurations identified and explained, the Occam BLC platform will be specifically addressed. Occam BLC-specific technology issues will be explained throughout the course yet limited to only that which is of IPTV significance. In addition, students return to their workplace with a clear perspective on how IPTV technologies specifically relate to and operate over their Occam BLC platform, internal networks and ADSL and/or fiber circuits. Anyone involved with installing, repairing and/or maintaining IPTV should attend.

The classroom learning environment is maximized by a sophisticated array of video examples of live IPTV networks and in-classroom IPTV equipment. These will be used at appropriate points throughout the course to explain and demonstrate technology details. Detailed, Occam-specific workbook diagrams are invaluable reference tools both during & after the class.
