7.7 Conclusions

There are a number of broadband access technologies which are capable of effectively providing access to broadband IP services. These technologies and their associated network platforms will continue to evolve. Broadband access is no longer just a 'fat pipe' many systems have increased functionality, configurable features and intelligence. Hence issues such as service provisioning, interoperability and CPE auto-configuration are increasingly important challenges that need to be overcome for mass-market viability.

The various broadband access technologies have their relative merits and all will continue to prosper as the insatiable customer demand for bandwidth continues. Many operators and service providers will use a combination of these technologies in order to best approach their target markets. In the UK some cable operators already use DSL on their 'siamese' cables which include coaxial cable (used by cable modems) and twisted copper pairs.

ISPs are using both DSL and broadband radio in the USA to increase customer coverage. Radio systems in conjunction with in-building distribution via DSL are being used to target office blocks. Satellite is increasingly being examined to expand broadband coverage to rural areas.

BT's current ADSL platform is well positioned to take advantage of the proliferation of broadband IP services. The platform has the capability to increase its functionality and evolve towards incorporation of APON and VDSL wireline technology.
