| Multi-Service Access Nodes from Nokia Siemens Networks Provides both H.248 and SIP Protocols At the European Broadband World Forum 2007 in Berlin Nokia Siemens Networks presents its strategy for Multi-Service Access Nodes. When broadband technology was introduced in fixed networks, DSLAMs went into Central Offices to be installed in parallel to the TDM switches. This principle will remain valid as long as voice service connections exist in a POTS/ISDN-connection based network. On the other hand VoIP has become a standardized and commonly used technology, and it will replace the obsolete existing PSTN equipment, offering lower costs in CAPEX and in OPEX. The transition from TDM-based voice to VoIP in the Multi-Service Access Node saves CAPEX and OPEX in the network. Both protocols – H.248 and SIP – are currently being used, but a clear trend toward SIP is visible. With this approach the move to building fully integrated, simplified networks is on its way to success. The presentation will be held in the Hotel "Estrel" on October 9th, 13.00 – 13.20 h. write your comments about the article :: © 2007 Networking News :: home page |
