  • To which customers and market segments Compelling reasons of each segment to enter Metro Ethernet market
  • Distributed softswitch architecture In the centre of the network, the infrastructure zone provides all the core VoIP functions: Basic VoIP call routing and every advanced service and regulatory features which are common for every voice applications. This infrastructure is scalable and reliable. A number of regulatory services like LNP and LI are common for every application, and are therefore positioned in the infrastructure. On the right, the Mobile and fixed public network termination terminates the SS7 or ISDN protocols. The infrastructures zone and the PSTN termination are sometimes combined in a single zone. The separation of the 2 zones shows that a number of functions like routing and Least Cost routing can be located in a generic VoIP zone which is independent from PSTN termination. On the left side, the ASP partners zone includes all the PC to phone or PC to PC applications. The IP PBX zone provides IP telephony and all the AVVID services. The residential and line zone focuses on broadband access services over cable, DSL or fixed wireless.

    3. 3. Is SIP ready for residential service over broadband ? STOCKHOLM, Sweden August 22, 2002 - Cisco Systems today announced that its technology will help enable the launch of a new residential telephone service by Bredbandsbolaget (B2), a next-generation Ethernet over fiber broadband provider reaching 220 000 households, which will provide a real alternative to the public switched telephone network (PSTN)-based calls in the residential market . With this end-to-end residential voice service B2 will be offering a competitively priced, fully functional telephony service using Voice over IP (VoIP), to its existing customers, as well as to new customers outside its established ISP service. B2 has opted to deliver calls over its Metro Ethernet broadband network using Session Initiation Protocol (SIP ), a flexible communications standard developed for the Internet and providing a simple, stable and cost-effective platform that can be used to integrate new services such as unified messaging in the future. video, which also makes it is ideal for the kinds of integrated services B2 is contemplating in the future.&quot; http://newsroom.cisco.com/dlls/prod_082202.html
