Protecting the Robustness of ADSL and VDSL DMT Modems When Applying DSM

Overview When transmitting data over an ADSL or VDSL link, performance is very important. In order to improve the bit rate that can be achieved over the copper link, a lot of techniques like power backoff (PBO) and dynamic spectrum management (DSM) focus on the crosstalk and try to operate with lower noise margin. Today's ADSL and VDSL modems are very robust. Both in ADSL and VDSL there exist reconfiguration protocols that take care of changing noise environments. The intent of the paper is to know what the impact is of DSM on the robustness of these systems.

Through the Fog: Who should protect you from viruses?

Many machines, notebook PCs in particular, now regularly leave the protective corporate cocoon and promiscuously connect to other networks out there in the big wide world - an open internet link on a domestic ADSL line, an ad hoc wireless network...

Quocirca's Straight Talking: From mainframes to grids and virtualisation...

A number of solutions exist to such problems, some (such as DNS round robin) are built into the protocols themselves, others are supplied by enterprising companies who recognise a need to be met when they see one.

Q&A: What will be at the centre of the digital home?

Meanwhile, we'll have many boxes at home, ADSL modems, wireless routers and another one if you buy a firewall, switches and a DSM 320 to play digital media. Why built an ADSL modem into the PC if I don't need it?

Broadband wireless gets spectrum boost

By comparison, traditional copper lines can usually offer connection speeds of between one and 24Mbps. The high bandwidth combined with narrow-beam signal technology means a very large number of broadband users can co-exist on the spectrum without...

Ofcom: Copper capable of high-speed broadband

The report does not specify the technology required, only stating that it is theoretically possible to go faster than VDSL (very high-speed DSL). According to the study, carried out by consultants Sagentia for Ofcom, around 18 per cent of the...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
