ISP/OSP – Inside Plant (ISP) and Outside Plant (OSP) Bonding and Grounding

ISP/OSP Course

iGround – What Sets Our Training Apart (PDF)

Course Objective

The objective for the ISP/OSP course is to provide attendees the necessary information to design, install, maintain, and troubleshoot grounding and bonding systems as they relate to Inside Plant (ISP) structured cabling and Outside Plant (OSP) locations; including maintenance holes, pedestals, aerial, and direct buried locations.


None but basic electrical properties knowledge and some telecommunication experience a plus.

Course Description

The ISP/OSP 4-day course will present the subjects relevant to OSP bonding infrastructure designs and installations. This non-vendor specific training will focus on both theoretical and practical knowledge of the different OSP configurations.

This course provides expert instruction beginning with the basic electrical properties and some of the myths that permeate the industry in regards to electrical principles and grounding systems. The full-color manual has plenty of high-resolution photographs to see the good, the bad, and the downright ‘ugly’ of electrical grounding and telecommunication system bonding poor design/installation OSP practices.

The ISP/OSP class has ‘hands-on’ portions that will offer the latest information on recommended test procedures, instrument techniques, and site survey testing checklists that are applicable for all types of systems and configurations.

Knowledge check quizzes are provided throughout the book so the student can better comprehend the material to answer the exact questions that may be posed to them during the design and installation process.

Throughout the instruction, ISP/OSP will emphasize relevant codes and standards such as the BICSI OSP Design Reference Manual, IEEE Green and Emerald books, the National Electrical Safety Code (NESC), the National Electrical Code (NEC), Underwriters Laboratories (UL), and others.

This class can be suited for open enrollment or suitcase training (with suitable space at customer facilities).
