SONET SDH Advanced Training

SONET SDH Advanced Training


SONET SDH Advanced Training Course Description

This SONET SDH Advanced Training course covers SONET/SDH in depth in the context of modern telecom systems including the new technologies such as Gigabit Ethernet. It includes enhancements to SONET/SDH including Virtual Tributaries (VT), Optical Transport Network (OTN), and Generic Framing Protocol (GFP). The SONET SDH Advanced Training course also relates SONET/SDH to MPLS and covers protection schemes and related topics. SONET/SDH technology forms the backbone of most large-scale telecommunications networks.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
