Course Information

This is a two-day course.

Course Base Fees: $1,000 USD

The SEL ICON Integrated Communications Optical Network is a versatile multiplexer purpose built for power systems communications networks. The ICON efficiently supports time-division multiplexing (TDM) and Ethernet traffic on a single platform and can also transport this traffic over SONET links.

The APP ICON course is interactive and activity-based. During this course, you will configure and implement a realistic OC-48 communications scheme and configure various circuits over SONET. Each unit of this course will guide you, step-by-step, through provisioning this comprehensive communications and protection scheme.

Equipment includes the following:

  • One ring of three nodes of the SEL ICON (either Protected Line Module [PLM] or Single Line Module [SLM])
  • One SEL-2407 Satellite-Synchronized Clock
  • One SEL-3360 computing platform with SEL-5052 Server Network Management System (NMS) Software to act as a client server (per class)
  • Two SEL-2726U Eight-Port Ethernet Switches

This course is intended for utility IT personnel, regulatory agency personnel, power system communications and automation engineers, and advanced technicians.

Course Outcomes

At the conclusion of this course, students can:

  • Identify the major features and functions of the SEL ICON.
  • Set up a node to configure, test, commission, and troubleshoot the following communications circuits for an OC-48 ring network using SEL-5051 NMS Software in a standalone environment.
    • IEEE C37.94
    • Transfer Trip
    • 10 Mb Ethernet
    • 100 Mb Ethernet
  • Configure GPS time source inputs for SONET frequency (SSM timing) and distributed time-of-day synchronization.
  • Configure security parameters in the SEL ICON to help meet NERC CIP requirements.
  • Perform commissioning tests to validate alarming and switching between nodes and around the ring.
  • Evaluate the differences between a standalone environment and a client/server environment with the SEL 5051/SEL-5052 Client/Server NMS Software.

Optionally, students will be able to:

  • Convert a SONET-based network to a virtual synchronous networking (VSN)-based network.
  • Groom DS0 circuits.
  • Configure, test, and commission other access modules.
