SDH
training course contents
Introduction to SDH
Timing and synchronisation of digital signals, the plesiochronous
digital hierarchy (PDH), the synchronous digital hierarchy
(SDH), service protection with SDH
SDH Multiplexing Techniques
The multiplexing principles of SDH, mapping and aligning
a 2Mbit/s tributary into a TU-12, aligning the VC-12 in
a TU-12, multiplexing TU-12’s into a TUG-2, multiplexing
TUG-2’s into a TUG-3, multiplexing TUG-3’s
into a VC-4, the VC-4 path overhead, the STM-1 frame, the
AU-4 pointer, the STM-1 section overheads, multiplexer
section protection, transmission at rates higher than STM-1,
concatenation line transmission functions in SDH
SONET Multiplexing Techniques
Mapping a DS1 tributary into a virtual tributary, aligning
the VT-SPE into a VT frame, mapping the VTGs into a STS-1
SPE, the STS-1 synchronous payload envelope, the STS-1
frame SONET network sections and lines transmissions at
higher rates than STS-1
SDH Functions and Facilities
SDH network topologies, structure of SDH equipment, synchronisation
of SDH networks, protection switching in SDH networks,
SDH alarm structure, SDH performance monitoring, testing
of SDH, equipment and systems, network management and SDH,
asynchronous transfer mode (ATM), future services and technologies
OSI Telecommunications Network Management
Definition of network management, managing telecom equipment,
the managed object library, the management information
base, the telecommunications management network (TMN),
the Q3 protocol |
