Hands-On Calix E7 Maintenance and Troubleshooting Virtual On-Site or Virtual Live Instructor-led

Course Description

This extensive Live Instructor-led course available for On-Site or Live Virtual delivery provides the skills required to perform detailed maintenance and troubleshooting on the Calix E7 optical network, including the various OLTs and ONTs within a typical network. It also discusses the theory and general system architecture used by various broadband systems such as AE, GPON, VDSL, and Ethernet-over-Fiber.

The GR-303 TDM Gateway interface for a traditional TDM switch is also explained, where examples can be shown for switches like a DMS-100 or GTD-5. Primary network elements are discussed including the OLT types, ONT types (SFU, SBU, MDU), plus various ONT options found within Calix's P-Series like the GX and GE, along with devices like Erbium-Doped Fiber Amplifiers (EDFA's), filters, splitters, transceivers, and different fiber cable and connector types. Various OLT interface cards are also described (AE GPON, SCP, power fan). Features like Ethernet, POTS, T1, and video, including RF-RTN from the Set-Top Box are explained, along with typical testing and use scenarios.

System management connection interfaces are described, and well as various administrative options, like the Web GUI Interface, Command Line Interface, CMS, etc. ONT activation and status is shown via local-PC connections, RONTA, Web CUI, and CLI, etc. along with discussion on provisioning of profiles, services, and VLANs, with reference to various system documents. System backup and recovery is also described, via external FTPTFTP servers.

Symptom investigation and troubleshooting is demonstrated using previous trouble examples, and through actual troubles which may exist in the network. Common fault types and best practices are also presented, to help prevent troubles from occurring in the first place.

Our non-intrusive exercises equip the student to conduct day-to-day maintenance activities and show how to perform troubleshooting procedures, including aspects of problem isolation, cabling and provisioning, which helps prepare students for higher-tier support interaction. The course is flexible, allowing the most important content for a particular group of students to be emphasized.

Target Audience

Technical staff such as Central Office Technicians, combo-techs, and those who are responsible for the maintenance and troubleshooting of FTTPVDSL systems, plus NOCSCC personnel who must respond to alarms. No previous background is required, although some familiarity with optical or ONT equipment would be beneficial. Certain management and provisioning personnel will also benefit, providing a greater understanding of the resources needed for the system, and how to support it.

Prerequisites

A basic understanding of telecommunications and networking principles is helpful due to the accelerated nature of the course. Any of our BTS fiber optic courses or our TDM Switching Fundamentals Course are available for students with little or no previous telecom background.

Notes

The course runs in a 5 day format, but can be combined or integrated with other topics like TDM Switching courses or Wi-Fi Best Practices for a full end-to-end training program.

The course is designed to run in ether a Live Instructor-Led Virtual Classroom or In-Person On-Site Classroom setting. Virtual Field Trips can be added to allow students an opportunity to see and understand where all the parts of the system are found, what they do, and provide a better end-to-end understanding of the network.

Delivery Method

LIVE Virtual and On-Site Live Instructor-led delivery available. With a flexible approach that adjusts content most relevant to students. Includes various non-intrusive labs, demonstrations, and exercises to help students focus on and retain the material presented.

Equipment Requirements
(This apply's to our hands-on courses only)

Students must have Virtual andor remote-access to a Calix E7 OLT for this training.

BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.
