Introduction to Transmission
Systems ISDN, ADSL, ATM & SDH
This 2-day course is designed to provide an insight
into the features and requirements associated with
the transmission technologies: ISDN, ADSL, ATM and
SDH.
Aimed at “field” personnel such as network
operators or their subcontractors through to those
responsible for the specification, planning and maintenance
of these transmission technologies, those attending
will gain a working knowledge of these common transmission
system technologies.

Course Content (100% Theory)
SDH technology overview
• The features & requirements, structure,
multiplex types, interfaces, services carried, network
sections, light sources. SDH Overheads: MSOH, RSOH,
BIPn, VC3/4 overhead, VC-12 overhead. Pointers: justification
mechanism, AU & TU pointers. Network Architectures:
the network architectures & how they work in terms
of protection. Network synchronisation: timing options
& order of events during multiplex section failures
ISDN technology overview

Interface (BRI) & Primary Rate Interface (PRI),
B, H & D channels, ISDN signalling, ISDN protocols:
I.430, Q921, Q931, Q932, Call Setup dialogue ATM technology
overview
• Basic principles, types of traffic supported,
ATM reference model, Functions & protocols of
the AAL, virtual paths, virtual circuits, permanent
& switched VCs, IP networks terminology, VPI,
VCI, ATM Header, Classes of service: CBT, VBR nrt,
VBR rt, ABR, UBR, QoS parameters DSL technology overview
• Principles, comparison with FTTH & LMDS,
differences between ADSL & G.Lite, SDSL, IDSL,
VDSL, CPE, DSLAM, RAN, Authentication, FTTC, transmission
concepts, ADSL over ISDN, use of splitters, comparative
speeds
