Directed Recovery
Available to BT ISDN30e and BT Featurenet 1000 and 5000 customers, the Directed Recovery service is “always ready” and is invoked following a request to a BT service centre.
The service ensures incoming voice, fax or data calls can be delivered Direct Dial In (DDI) number by DDI number to alternative telephone numbers during periods where buildings or offices become inoperable or inaccessible, or when the communications link to the serving local exchange, the Digital Local Exchange (DLE), is lost.
Directed Recovery is a normally passive service. At the time of an incident the service requires the customer to make a single telephone call to a 24 hour BT Service Centre to request the re-direction of all inbound calls to the service.
As a hosted, fully managed, service it eliminates the need for equipment or software in either the building being protected or in the DLE.
The service can work in conjunction with the BT Dual Parenting service, which together provide protection against the failure of the DLE, the cable between DLE and the offices being protected, and the offices themselves.
Notes:
This service requires BT iSDN30 Site Assurance or Featurenet Re-direct as a pre-requisite, as they are used to re-direct calls to the Directed Recovery service. Both of these services are ordered separately from BT.
The Directed Recovery service available on the PSTN requires that the customer uses ISDN30e lines in order to guarantee that the original call information is preserved and passed to the service. Where older specifications of ISDN30 lines are used these must be upgraded. This may also require an update to the customer equipment connecting to these lines.
BT Featurenet 1000 and 5000 lines are supported by the Featurenet version of the service.
