MUNICH -- At this year's Broadband World Forum in Paris, Siemens Communications is showcasing IPTV alongside the associated infrastructure components for Carrier Ethernet and optical networks. Europe is one of the main markets for the Siemens Group. The exhibits can be seen at Booth 2000 in the CNIT La Defense Conference Center.

Lower costs for operating fiber-optic lines: Surpass hiT 7300 Paris will be the world premiere for Surpass hiT 7300's live performance, a completely new DWDM (Dense Wave Division Multiplexing) platform for optical networks. Surpass hiT 7300 addresses the metropolitan, regional and long-haul network segments and is therefore suitable for all applications from high-density areas to regional backbone networks. The special feature of the new transport platform from Siemens is its high level of automation, which enables Surpass hiT 7300 to significantly reduce the costs for installation and ongoing operation and to make the ROADM (Reconfigurable Optical Add-Drop Multiplexer) technology, which has been very successful for long-haul applications, cost-effective for shorter transmission distances as well. In connection with a GPON (Gigabit Passive Optical Network) system from the Surpass hiX 57xx series, Siemens will demonstrate an end-to-end optical transport line in Paris that achieves data rates of up to 2.5 Gbps.

Broadband access technologies for copper lines To bring entertainment formats into customer homes with the best possible quality, Siemens offers a full range of broadband access technologies. With its Surpass hiX 5625/30/35, Siemens presents IP-DSLAMs (Digital Subscriber Line Access Multiplexers) that feature the mixed use of voice (analog connections and ISDN) and data (xDSL and Ethernet connection versions) within a single device (shelf). All connection cards (xDSL, POTS and ISDN) can be used each of the three shelf types. Thus these devices become real Multi Service Access Nodes (MSAN). Moreover, thanks to the high density (e.g. 72 ADSL2+ ports per line card) at the Siemens systems, more connections can now be squeezed into a small space, thereby reducing infrastructure costs.

Controlled by a softswitch, the voice traffic is first converted from TDM to VoIP and then forwarded via the aggregation network (Carrier Ethernet) to the IP network. Together with the other data, the voice information is then modulated into a single data stream and forwarded via the DSLAM's same Gigabit Ethernet connection to the next network layer. This brings high flexibility saves space in collocation rooms as well as in "street cabinets" Further more Network providers can use them to convert their infrastructure to IP without having to migrate their existing analog subscriber lines to IP.

MSANs transmit the voice data via the protocols H.248 or SIP, which are used by IP softswitches to control the connection setup and to monitor the voice transmission. The existing TDM network is no longer needed. By the end of 2006, Siemens will have completed interoperability tests for this solution with four of the leading softswitch vendors. As a result, network providers will be able to benefit from Siemens's hiX 5625/30/35 MSAN systems even if they use softswitches from other manufacturers.

The Paris trade show will also see live the smallest shelf-based IP-DSLAM from Siemens, the Surpass hiX 5625. This DSLAM, which features five VDSL2 card slots, is used by Deutsche Telekom to upgrade its existing copper network for extreme broadband applications such as IPTV and other home entertainment offerings.
