1 day
Training Course Description:
The next generation of telecommunications networks will deliver
broadband data and multimedia services to users over a core that
supports IP over MPLS. In order to achieve the migration to this
future IP only service, existing Signalling Systems must be made to
interoperate with new control mechanisms. When the existing circuit
switched infrastructure disappears so too will the service paths that
support the signalling network. It will become necessary to carry
existing SS7 interconnections over the new IP infrastructure and to
interoperate new packet based telecommunications and voice services
with existing international circuit switched telecommunications.
Transition to the new services has already started in the UK and the
current plans expect a complete migration, replacing all existing ISDN
local exchanges by 2010. It therefore will become vital to carry
exiting SS7 interconnections over the new converged IP infrastructure
and to interoperate mobile and fixed international networks using SS7
with new VoIP infrastructures. The first step in this transition
requires the carriage of SS7 over IP.
This course provides an understanding of how can be achieved, the
protocol architectures used and an overview of the implementation
aspects of such developments. It will provide an understanding for
implementers, designers, managers and infrastructure engineers that
need to plan, implement and use the new generation of networks and
services.
When you have completed this course you will be able to:
- Describe the basic protocol
architecture needed to carry SS7 over IP
- Select the appropriate options and
mechanisms development of new signalling services
- Compare services provided by TCP,
UDP and IP with SS7 Message Transfer Part
- Build infrastructures using SCTP
to carry SS7 over IP effectively
- Provide reliability by deploying
the re-routing options in the event of failures
- Deliver Intelligent network
services over IP
- Carry TCAP, ISUP and Q.931 ISDN
Access Signalling over IP
