Understanding
MultiService Access and SIP
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.
