Training Course Outline
Course Duration:
2 days
Training Course Description:
This document describes a two-day workshop on Multiservice access
using PPPoE/PPPoA/VLANs and SIP. 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. SIP-T or MEGACO can be
deployed to achieve this.
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.
This course will provide an intensive study of these technologies.
