This lab-intensive course introduces you to the Cisco Optical Network System (ONS) time-division multiplexing (TDM) family of transport products. The Cisco ONS 15454, ONS 15600, ONS 15310-MA, and ONS 15310-CL are SONET transport system components that can be mixed and matched to create high-speed optical transport networks. You will learn about the SONET optical hierarchy OC-3 (155 Mbps), OC-12 (644 Mbps), OC-48 (2.5 Gbps), and OC-192 (10 Gbps). You will learn how DS-1 (1.5 Mbps) and DS-3 (45 Mbps) electrical signals are carried in the SONET optical links. The course covers Ethernet circuits at Layer 1 and Layer 2 using CE and ML cards. Included in this course is how to configure and build circuits through the ADM10G card, a TDM card in the ONS 15454 DWDM system. The course covers electrical, Ethernet, and optical protection options; linear and ring topologies; circuit building; and troubleshooting. Each student team has an ONS 15454, ONS 15600, ONS 15310-MA, and ONS-15310- CL to work with.

The course is available only as a private group training (up to 12 people).
