C4/C5 Replacement: Next-Gen Services and the Reasoning behind a Complex Network Transformation

Wednesday June 16, 2010 TIME: 11:00 Central European Time (CET)

This webinar provides an insight into, and a justification for, the migration process and the transformation of a wireline TDM communication network to an IP-based VoIP network. In reality, the complete replacement of legacy Class-4 and Class-5 services is happening right now and is one of the priority plans for every operator. However, the entire replacement process is a very complex one, and the replacement of the Class-4 and Class-5 infrastructure is an unpleasant business. In the case of C4, the interoperability connections and integration with existing OSS/BSS systems are at stake, and in the case of C5, the risks are connected to the range of services and applications that are already in use.
The reason for the replacement is the OPEX savings on obsolete TDM networks and, simultaneously, in the investments in a new network architecture, the NGN or IMS and in introduction of new next-gen services.
With an IP network and a new service-delivery platform, the operators are able to rapidly deploy new multimedia services to residential users as well as to highly demanding business users.

What the attendees will learn:

  • The motivation behind a decision to replace the Class-4 and Class-5 infrastructure
  • The means and paths that operators are most likely to follow when moving services to the new softswitches (the step-by step approach)
  • Which new revenue-generating multimedia and VoIP services the IP core network will bring
  • How a two-step approach (an intermediate NGN before moving to IMS) preserves a telco’s investment

Who should attend:

Telecom operators and carriers with a TDM core and PDH/SDH network infrastructure that are moving to an IP infrastructure and transforming their existing services to VoIP-based and keeping the same user experiences



After the presentation, the Webinar will be open for a live Q&A.
Be sure to have your questions ready!
