Hands-On PDH/SONET/SDH Networks Virtual Live Instructor-led or On-Site

Course Description

The Understanding PDHSONETSDH Networks course has been developed to quickly on-board those new to telecom transport. While PDH and SONET are the main focus of the course, SDH is also explored and compared, in cases where employees encounter the use of this standard in the field.

Plesiochronous Digital Hierarchy (PDH) circuits are
discussed first, both for their legacy and ongoing role
within the telecom network, and also for their basis as
SONET's VT1.5 and STS-1 frames. Fiber optic
networks are also discussed and compared to electrical signal transport, including the nature of synchronous and asynchronous circuits, and the need for a synchronous optical network. The SONET protocol is then looked at in more detail, including the use of overhead to provide alarm, pointer, DCC and other information as signals traverse different layers of the SONET model. Synchronous Digital Hierarchy (SDH) is then explained and compared to SONET, along with speed and frame differences.

Various test equipment is also demonstrated, such as PDH (DS1DS3) and SONET test sets, as well as optical inspection and OTDR instruments. Finally, Laser safety, fiber optic routing, cleaning and care are also emphasized.

Students Will Learn

Asynchronous PDH circuits like DS1 DS3
TDM, FDM, WDM, DWDM
How and where PDH circuits are used
SONET Protocol sublayers
SONET Overhead including alarm, pointer, and DCC bits
SDH Protocol

Target Audience

Central Office and network installation techs, network support personnel in NOCSCC, management, and others seeking an understanding and troubleshooting skills with PDH, SONET and SDH circuits.

Prerequisites

Due to the accelerated nature of the course, a general understanding of central office procedures or transport networks may be helpful, but are not necessary. Previous experience with transport-related test equipment may also be helpful.

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

(This applies to our hands-on courses only)
It doesnt have to be just our Company.

I wont have 10 people per course (DMS 10DMS100). Probably have 6-7 for DMS10 and 7 for DMS100 course.

Thanks,

Amanda

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.
