Improving Bandwidth Utilization by Implementing DOCSIS 2.0 Logical Channels

Tags:
bandwidth issues

Overview DOCSIS 2.0 support for logical channels allows cable operators, who deploy standards-based DOCSIS 2.0 Cable Modem Termination System (CMTS) platforms, to provide significant amounts of increased upstream bandwidth. They can quickly deliver increased upstream performance to HFC networks consisting of mixed mode DOCSIS 1.x and 2.0 cable modems as well as for new networks consisting entirely of DOCSIS 2.0 cable modems. Today, operators run the lowest common denominator modulation mode that supports the weakest cable modems on the network. But DOCSIS 2.0 introduced the concept of logical channels to provide the ability to optimize the throughput of DOCSIS upstream carrier frequencies by segmenting cable modems on the same physical network according to their potential to deliver higher-performance upstream throughput.

Is the game up for ISDN?

ADSL is not symmetric and so can only transmit data upstream at speeds of 640Kbps - still 10 times faster than a single ISDN connection. ADSL, on the other hand, slows down to 16Kbps upstream and 2Mbps downstream over the same distance - although...

SOS: Finding your way through the broadband acronym jungle

But it is important to have fast upstream access in place if the company decides to host its own servers. ADSL is more suitable for residential users and small businesses as they would mostly use it for downstream access, that's to say downloading...

Ethernet promises cheaper broadband

However, few people have the necessary fibre-optics to their home or office, and service providers have so far based their networks on the rival ATM (asynchronous transfer mode) protocol. Instead of adding more expensive ATM channels for new...

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.
