2 days
Training Course Description:
This two-day instensive course examines Multiservice access using
PPPoE/PPPoA/VLANs and H.248 (MEGACO). The next generation of
telecommunications networks will be deployed using VoIP technology and
soft switching replacing circuit switching and ISDN signalling. By
deploying communications as multimedia streams over IP it is possible
to extend the services from simple voice to improved voice quality,
better bandwidth utilization and expanded services into video and
television carried over the same technology. Already cost effective
VoIP services have been deployed using H.323 and SIP over Intranet
infrastructures. However to integrate this with existing ISDN and SS7
architectures and eventually to replace local exchanges and transit
exchanges in carrier networks requires large scale signalling and
switching changes.
The next generation of telecommunications networks is likely to use IP
and for efficient and high-speed quality of service switching deploy
MPLS to select routes.
To build soft switches and distribute the switching function over a
carrier level infrastructure, gateways will be controlled using H.248,
called Media Gateway Control Protocol (MEGACO) by the Internet
community.
This course will provide an intensive study of these technologies.
When you have completed this course you will be able to:
- Describe how PPPoA functions today
- Migrate access to PPPoE and VLAN
operation with Gigabit Ethernet
- Discuss the mechanisms used to
carry voice over IP
- Compare SIP, H.323 and Media
Gateway Control Protocol
- Employ MEGACO to build soft
switches
- Analyse H.248 protocol exchanges
