As promised, I'm sending you an update which we have sent to our service
provider customers. I hope this helps and I'm keeping my fingers crossed
that this solution works for you.
Kind regards
INTRODUCTION
Current Broadband technology is delivered via BT's
copper network. However in some areas of the UK where a copper route is not
feasible due to distance limitations, TPON (Telecommunications over Passive
Optical Network) has been used instead to ensure that we can comply with our
obligation to provide basic telephony service to all potential customers. In
these areas the connection from the street cabinet back to the local
telephone exchange is by optical fibre rather than copper cables. As there
is no metallic path back to the local ADSL enabled exchange, TPON served
customers will currently fail a line qualifying check for broadband.
UPGRADE PROGRAMME
We have identified a number of TPON areas that are within the theoretical
range of a broadband enabled exchange and where existing copper networks can
be utilised or built upon, subject to cost. Our solution involves switching
the lines of people in TPON areas who want broadband to newly installed
copper cables that overlay the fibre, or to limited existing overlay copper
cables. Please note that in some cases the customers' telephone number may
need to be changed.
The programme of work to plan and install new copper cables to these TPON
areas is underway with the first few completed sites available from early
June 2003.
Exchanges that become enabled through the pre-registration scheme and local
partnerships will also be reviewed for the presence of TPON in their areas
and, subject to cost and technical limitations, be added to the upgrade
programme.
A regularly updated spreadsheet of the TPON areas that are being upgraded
will be made available to service providers from early June. This
spreadsheet will provide information on the progress of providing copper to
selected TPON areas from the planning stage to completion. Service Providers
will be able to use this information to advise their End Users who are in
TPON areas of the likely dates for getting broadband service.
Although we anticipate that the majority of customers in a fibre-fed area
will be able to receive broadband over copper from their ADSL enabled local
exchange it must be stressed that not all customers will be within reach of
ADSL technology.
ADSL AVAILABILITY CHECKER
>From the end of May 2003, the on-line ADSL availability checker will be
updated to change the availability RAG result for a telephone number in a
TPON area from a RED to AMBER. The associated message will also be changed
to advise customers that they may be able to receive service subject to
further checks and survey. An order placed by the customer with their
Service Provider will be subject to survey to check the availability of
copper wires in the TPON area. This survey will also check that the customer
is within the maximum reach of the ADSL technology. Service Providers will
be asked only to place orders for sites that are completed having checked
the programme schedule mentioned earlier in this brief. |
