Broadband
With many providers out there all shouting loud and proud about their broadband solutions why should you use DBfB Communications as your provider?
As telecommunications evolved in the UK, BT deployed a number of disparate and unconnected networks to provide a range of services - from basic telephony to complex Internet connectivity. This approach inevitably left BT with a number of issues when looking to provide the next generation of high speed data connectivity. Its technical experts therefore proposed a radical replacement programme that takes the network to a single unified core.
The 21CN infrastructure
Under 21CN (21st Century Network), by 2012 BT is replacing traditional concentrators, switching equipment and DSLAMs (Digital Subscriber Line Access Multiplexer) at exchanges with MSANs (Multi-Service Access Nodes). The 5,500 MSANs terminate all phone and broadband connections and link into over 100 ‘Metro nodes’ where IP packets are routed and switched. The Metro nodes then link to 20 core nodes that are able to handle traffic in multiples of 10Gbps.
What are we doing
DBfB Communications, with its partners have been proactively involved in the development of 21CN, being particularly influential in the ‘Consult21’ working groups through which it has represented the channel by helping shape the network, the characteristics of the service offerings and the methodology that has been applied to migrations.
Under 21CN we have taken WBC (Wholesale Broadband Connect) in order to provide a number of new broadband products that enable us to compete effectively in the market. This approach represents significant investment on our partners part and has required it to build out its existing UK network to cover the 20 core nodes. Initially using Gigabit Multi-Service Interconnect Links (MSILs) at each of the 20 nodes to take delivery of individual connections onto its own network. As capacity requirements increase these will be upgraded to 10Gbps connections.
As well as its involvement in the Consult21 process, Our partner has been the only non-BT company involved in the service trials of BT’s WBC. This involved a number of customers on 10 exchanges connected to the Birmingham node having a second ADSL line installed in order to test the speed and reliability of the new high speed broadband connections.
