For Out of Area Service normal ISDN30 Connection and Rental charges apply. In addition Out of Area Charges apply. (Note: Distances are measured to nearest km rounded up and are calculated as radial distances.)

Alternative Routing - Only available for new supply via the EMP interface (WLR3)
Alternative Routing gives customers connection to their normal serving exchange over two different routes involving different cables and/or ducts (if available) and/or building entry points (if available), to a level requested by the customer.
Full ISDN30 connection and rental charges apply for channels which have been alternatively routed, the first alternatively routed transmission bearer attracting the New Installation Charge. In addition there is a minimum requirement for 8 channels on both the main and alternative route.
Where new network build is required, e.g.new ducts or fibre, Excess Construction Charges will apply and can be found in `Excess Construction Charges' in the Service Products section of this Price List at :
http://www.openreach.co.uk/orpg/pricing/serviceproducts.do
Diverse Routing - Only available for new supply via the EMP interface (WLR3)
Diverse Routing gives customers connection to a second exchange designated by Openreach, in addition to that used for their normal ISDN30 service. This provides two different routes involving different cables and serving exchanges and different ducts (where possible) and building entry points (if available).
Full ISDN30 connection and rental charges apply for channels which have been diversely routed, the first diversely routed transmission bearer attracting the New Installation Charge. In addition there is a minimum requirement for 8 channels on both the main and diverse route.
Two options are available for supplying this:
One option allows connection to an adjacent exchange by linking to the adjacent local access network by the use of network build charged as Excess Construction Charges.
Where new network build is required, e.g.new ducts or fibre, Excess Construction Charges will apply and can be found in `Excess Construction Charges' in the Service Products section of this Price List at :
http://www.openreach.co.uk/orpg/pricing/serviceproducts.do
The other option allows connection to an adjacent exchange by routing the adjacent exchange via the local exchange and then over the BT transmission network.
For this option Out of Area charges will apply.
Site Assurance enables Communication Provider End users to have their calls rerouted to an alternative site if their normal site becomes unusable for any reason. This can be achieved by:
Wholesale ISDN30 Site Assurance - Option 1
Use of basic call diversion to route all calls to a pre-arranged single number.
|
Where site assurance is applied to a group of channels in a number group, all channels in that group must be invoked together.
In addition:
Call charges will be raised for the diverted part of each call when the diversion is activated.
Full ISDN30 connection and rental charges apply for channels at the standby site, i.e. the first transmission bearer attracting the New Installation Charge. In addition there is a minimum requirement for 8 channels on both the main and standby sites.
Additional charges will apply if the standby site requires Out Of Area routing and/or Excess Construction Charges.
In addition Site Assurance Option 2 charges will apply.
|
Where site assurance is applied to a group of channels in a number group, all channels in that group must be invoked together.
(Note DDI Dual Parenting price does not include any element of line charges or DDI number charges, these are charged separately)
DDI dual parenting is an option that enables ISDN 30 DDI to continue operating in the event of a customers local exchange failure. This is done by connecting the customer to 2 separate local exchanges but keeping the same DDI telephone number range across both exchanges. The DDI Dual Parenting service is only available for DDI ranges of a minimum 1000 DDI numbers and in blocks of 1000. i.e. 1000, 2000, 3000 etc.
Connection to the two Dual Parenting switches may use normal installations, Out of Area service, Diverse Routing or Site Assurance Option 2 and these would be charged separately.
