During the processing of your order for an ISDN to ADSL conversion, standard checks carried out from your local exchange by BT have indicated that your telephone line is not capable of handling the required ADSL feed. This is because your line has failed testing on one of the following parameters:
- for ZenADSL Home 1000, the line length must be no greater than 6km
- for ZenADSL Home 1000, the noise level must be no greater than 62dB
- for ZenADSL Home 1000, capacitance level must be no greater than 300nf
All relevant checks must be passed in order to support ADSL and unfortunately your line has failed one or more of these tests. We regret to inform you that as a result your conversion order has now been cancelled. Please note that your existing ISDN service will resume on this line and will not be converted as part of the current order. We will be making a full refund of all payments for this order as soon as possible.
....How can the tests fail without an engineer even entering my house, I thought ISDN had to be disconnected first, I know my line length is less than 6km, noise level must be less than 62db as that was a requirement for ISDN. Any comments?, or can it all be done from the exchange now without entering the house?
