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. Perpetual Solutions has released a series of courses to provide the the skills required by telecoms and data networking professionals to understand, develop and implement these new technologies.
Next Generation Networks, IMS, SIP, SIgTRAN, and IN This course provides an intensive 5-day examination of many of the new technologies being incorporated in IP NGNs. It also charts the roadmap from legacy PSTN and GSM systems towards NGN.
Understanding MSAN and H.248 This course provides an understanding of Multiservice access using PPPoE/PPPoA/VLANs and H.248 (MEGACO).
MPLS in 21st Century Networks This course provides an understanding of how MPLS works, its advantages and limitations and how it can be deployed to provide effective services over a 21st Century converged network.
IP Multicasting for Multimedia Distribution Networks This course provides an understanding of how IP multicasting works, its advantages and limitations and how it can be deployed to provide effective services over a 21st Century converged network. It will demonstrate examples of multimedia service configurations in the class-room and identify practical problems and their solution.
SS7 over IP (SCTP) This course provides an understanding of how 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.
H.248 Megaco for Developers and Implementers This course will provide developers an introduction to this H.248 technology, how it has evolved and how it can be used. It will give and understanding of the commands and parameters used as well as providing examples of exchanges needed to set-up typical calls.
Gigabit Ethernet for Telecommunications Service Networks This course will provide a detailed understanding of Gigabit Ethernet for implementers, designers, managers and infrastructure engineers that need to plan, implement and use the new generation of networks and services.
Understanding DOCSIS (Data Over Cable Service Interface Specification) DOCSIS is a set of standards produced by the Cable Television industry for delivering Internet access and other data services over traditional cable television Networks. This course provides an understanding of how IP multicasting works, its advantages and limitations and how it can be deployed to provide effective services over a modern Cable TV network.
Understanding Packet Legal Intercept Law enforcement agencies require the ability to intercept voice and data calls without the user being aware of the interception. This course provides an understanding of how Legal Intercept may be added to 21st Century converged networks.

As computer and telephony integration proceeds at the enterprise and medium to small business level, present voice and data networks will combine to become a single organisational resource. The ability to route voice traffic over an IP network will result in major cost savings as the separate network functions are are combined within one multi-purpose entity. This course looks at the benefits, standards and present problems with Voice over IP and seeks to define the future potential. This course is excellent for anyone wishing to gain a solid introduction to this technology.
A program of Voice over IP courses are being held in the following locations; London Bristol Birmingham, Manchester, Newcastle and Edinburgh. The cost of the course is £795 (+VAT) per delegate. Places are limited so book early to avoid disappointment. To make a booking please call the Sales Team on 020 7620 0033 or email enquiries@perpetual-solutions.com. This course is also available to be delivered onsite.
The importance of networks has never been higher and the ability of networks to survive faults is of ever increasing interest to both carriers and their customers. Resiliency and restoration in core SDH networks has long been based on the Automatic Protection mechanism of SDHs APS coupled with the design of the network as a series of interlinked rings.
This works well and very quickly but is very expensive in that 50% of the network capacity may be sitting idle just waiting for something to fail in the other 50%.
IP, the Internet Protocol has its own mechanisms for avoiding faults but these have traditionally taken far too long for many users, involving as they do, route discovery protocols noticing that something is wrong followed by routing messages telling all nodes about alternatives. If multiple recovery mechanisms are present in the same network (using IP, ATM and SDH together, for example), they can defeat each other’s best intentions.
This is a recognised problem and new mechanisms are emerging that offer the high speed of SDH rerouting together with far less idle capacity and better alignment with the IP/Ethernet-based traffic of today.
This course examines these emerging techniques after providing a basic introduction to resilience and survivability of networks, including:
