Filed:

Sep 18, 1998

Appl. No.:

09/157222

Barbara E Walsh - Woodstock GA
Marcus L White - Suwanee GA

Assignee:

ATT Corp. - New York NY

International Classification:

H04M 310

US Classification:

379279, 379292, 37922103

Abstract:

Restoration of an inoperative network element ( ) such as a digital cross-connect system is accomplished by receiving updates from each element as they occur in a local controller network ( ). The local controller network forwards the updates to a DCS-Operations support system ( ) that generates a restoration map for each element in its native language, and thereafter updates each map upon receipt of each update. In response to a user command, the DCS-operation system directs (transmits) the update map either to directly the inoperative element or to an intermediate element to achieve restoration.

AT&T Corporation - New York NY

International Classification:

G06F 11/00

US Classification:

714 4, 714 3, 709221, 370216

Abstract:

There is provided a system and method of disaster restoration of service of damaged or destroyed telecommunication network elements. A controller component is configured to select a damaged or destroyed network element after a disaster event. An engine component is configured to establish connectivity to an alternative network element and to transmit the service continuity data associated with the damaged or destroyed network element from a computer readable storage. The engine component is configured to execute one or more computer commands to the alternative network element so as to operate it with the service continuity data of damaged or destroyed network element. A restoration service package is transmitted to a replacement network element and instructed to use that service package to re-acquire the original network element's identity and provisioning information in order to restore the traffic that originally existed on the damaged or destroyed network element.

International Classification:

G06F 11/00

US Classification:

714 4, 714 6

Abstract:

There is provided a system and method of disaster preparedness and restoration of service of damaged or destroyed telecommunication network elements. A computer-implemented method of disaster backup for network elements includes establishing connectivity to a plurality of network elements. A host computer may transmit one or more commands to the network elements for invoking a computer routine to create a plurality of computer readable service continuity data to a local memory of the network elements. An automated system of computer executable components for disaster recovery of network elements includes a computer executable controller component that is configured to select a plurality of network elements designated for disaster backup action. A computer executable engine component is configured to establish connectivity to the plurality of network elements and to transmit one or more commands to the network elements so as to replicate service continuity data for each of said network elements.

Appl. No.:

Inventors:

Richard L. Guzman - Holmdel NJ

Assignee:

AT&T Corp - New York NY

International Classification:

C06F 1300

US Classification:

714 4

Abstract:

Full restoration of a telecommunications network element (12), such as a digital cross-connect system (DCS), is accomplished by receiving from each element provisioning updates as they occur in real time via a local controller network (18). The provisioning changes are stored, typically via a local controller library (20). A DCS-OSS data base (22) creates and stores restoration maps for each DCS and, in response to updates from the local controller library 20, the DCS-OSS data base updates the stored restoration maps. Should a DCS become inoperative, that DCS can be restored (either by itself, or on another DCS) using the restoration map. Since the map contains the most up-to-date data, full restoration can be readily achieved.
