SURPASS DSL Broadband Access is the perfect solution to fulfill all of your customers’ bandwidth demands in this respect. It reduces CAPEX, bringing all types of DSL technologies, whether ADSL, ADSL2+, SHDSL or VDSL, onto a single platform. Deployment is optimized through best-in-class port density, comprehensive attachment options and full scalability whatever your network scenario. A mass rollout of DSL services is a big challenge for any carrier. Siemens sup — ports you all the way with its manufacturing strengths, logistics and services — complete and proven end-to-end solution delivery with easy network integration and interoperability from one source is our specialty.
The first challenge facing carriers in today’s networks is how to solve the last mile bottleneck. DSL technology is the ideal technology to address this. It lets you offer more bandwidth to residential customers over existing copper lines previously used for low-speed dial-in Internet access.
More and more Internet users want to enjoy high speed Internet access at home as well as in the workplace, and residential customers are willing to pay a premium for this increased bandwidth. Both wide area network bandwidths and PC performance (including peripheral connectivity bandwidth) are growing tremendously to accommodate fast Internet access. The last mile has therefore become the bottleneck in allowing this high-bandwidth traffic to be transported to the core network.
Voice carriers already possess an installed copper infrastructure, but not more than 56 kbps are typically used to access the Internet. DSL technology utilizes this infrastructure and increases the available data bandwidth dramatically with ADSL (and even more so with VDSL). More data are being brought to the customer premise, and this in turn increases carrier revenue. With broadband access, services like gaming, peer-to-peer connections, voice and video over Net — Meeting and second line support with Voice over DSL are becoming more than attractive. DSL of course continues to allow access to existing narrowband telephone services (POTS and ISDN) over the same copper pair. Due to the fact that the copper infrastructure is reused and exploited, this is a highly effective way of reducing the last mile bottleneck without deploying expensive fiber to the home.
Voice, Data and Entertainment Services for the Residential Customer Carriers must diversify and offer value — added services to counter subscriber churn due to strong competition from mobile and cable TV service providers. The delivery of broadcast TV, Video on Demand, gaming and other multimedia applications over DSL allows carriers to offer a true ‘Triple Play’ service mix of telephony, high — speed Internet and entertainment, all served over the same last-mile access net — work. These TV-centric content-on-demand applications and services on top of high-speed Internet and telephony offerings bring new revenue generating options with very little CAPEX investment.
Supplying the Right Services for Business Customers
There are several ways of addressing business customers with the services that they need, and the first example we will take is that of Internet Access and Voice over DSL with SHDSL.
Voice over DSL (VoDSL) using SHDSL is used for transmitting converged voice and data services. Voice is given a higher priority than data; therefore voice quality is consistently guaranteed and equivalent to TDM voice. Bandwidth is flexibly shared between voice and data using dynamic bandwidth allocation to meet the customer’s actual needs. Several voice and data connections can be offered on one single copper pair, optimizing use of the existing copper infrastructure and thereby minimizing cable infrastructure costs and safeguarding existing investments. This is made possible by using Integrated Access Devices (IADs), which concentrate several voice ports and one Ethernet interface onto a single ATM over an SHDSL line towards the DSLAM. On the central office side, a voice gateway transforms the voice over ATM signal back into the appropriate narrowband TDM signal to transmit it to the voice switch.
The second example illustrated here ad — dresses VLAN support: implementing IP security instead of simple Ethernet bridging, with VLANs providing additional separation of LANs and broadcast/multicast control over switched Ethernet environments. VLAN enhances the security and separation of individual customers. The Ethernet net — work interface allows the network operator to connect the DSLAM via an Ethernet core network to a more centrally located BRAS or directly to the core IP network. In addition a SURPASS hiD Multi-Service Packet Switch can be deployed for further aggregation and switching.
