Hands-On LIVE Virtual Calix E7 Maintenance and Troubleshooting (AXOS)

Course Description

The Calix E7-2 Maintenance and Troubleshooting (AXOS) Virtual Live Instructor-led course provides the skills required to perform detailed maintenance and troubleshooting on the Calix E7 system, including with various OLTs and ONTs found within the latest XGSPON and NG-PON2 networks, as well as AE and Ethernet networks. It discusses the theory and system architecture used by the latest Calix AXOS-enabled networks, and compares this to previous EXA networks.

Multiple new features are discussed, including the latest 10G-capable ONTs, as well as existing GPON AE ONTs. The GR-303 TDM Gateway interface for a traditional TDM switch is explained, which is still used in many networks. Primary network elements like the latest OLT cards are introduced, including GPONXGSNG-PON, plus CE201 and other AXOS-enabled GE cards. FTTP components are discussed, including Erbium-Doped Fiber Amplifiers (EDFA's), filters, splitters, transceivers, and different cable and connector types. Both the E7-2 and E7-20 are described, although a focus is placed on the E7-2 which supports the latest AXOS offerings. Features like 10G Ethernet, POTS, T1, Pseudowire, and IPTV are explained, along with Ethernet-over-Fiber uplink options including LAG, and fiber ring protection schemes.

The latest Services Management Connector (SMx) is shown, and compared to the existing Calix Management System (CMS) and the limited EWI web interface, along with Command Line Interface (CLI). ONT activation, status, and replacement procedures are shown using local-PC connections and SMx. The various types of logs, plus performance monitoring options are shown.

System backup and recovery are also described, as well as basic provisioning steps. The newer features of AXOS are introduced and compared to original EXA systems. EXA is not emphasized in this course due to time constraints, but is found in the Calix E7 EXA maintenance course.

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, including fiber and transceiver inspection and cleaning using modern equipment.

Our non-intrusive exercises help equip the student to conduct day-to-day maintenance activities and show how to perform troubleshooting procedures, including problem isolation, module replacement, and provisioning, all of which help 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

Notes

The course can be combined or integrated with other topics like TDM Switching courses or Wi-Fi Best Practices which includes further study with Calix wireless access points like the 844G and GigaSpire, or other integrated ONTs.

Those interested in understanding more about AXOS-enabled hardware and the features of AXOS may be interested in the Calix E7E9 AXOS version of the course, which emphasizes these features over the standard EXA version.

Delivery Method

LIVE Virtual Instructor-led with a flexible approach that adjusts content most relevant to students, including various non-intrusive labs, demonstrations, and exercises.

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 experience using their specific equipment.
