Advantages ATA provides significant work-hour savings and other benefits, such as finding and repairing errors in current databases and significantly minimizing post-cutover rework and trouble calls. Human error is eliminated because all data movement is automated. Complete telephone switch data is transferred to a new switch for testing months in advance and then again just before cutover, thereby eliminating the need to duplicate software changes in both the original and new switch during the pre-cutover period.
The drawing on the right illustrates the flexibility of ATA's processes to support a variety of cutover approaches including "flash’ cutover of all ports or the cutovers done in many steps in support of customer needs.
Pre-Cutover Pre-cutover analysis of the source switch and precise detailed cutover planning is essential to the success of any cutover. Some of the services provided include the following:
- Existing Switch Configuration Summary Proper planning for new switch cutovers requires key details of existing telephone systems, including automated and comprehensive system totals, counts for assigned and unassigned lines/ports, special features, and trunking/routing information.
-Directory Number & Cable Information Creation of a single document, aggregated from relevant databases is used to verify existing software and hardware configuration and port wire assignments prior to cutover. This document can be updated as often as necessary to allow the cutover team to keep up with corrections and service changes thereby eliminating difficulties experienced with manual procedures. Detail is provided for every telephone number such as current port assignment, feature summarization, hunt group status, cable pair information, and new port assignment.
Customer Enhancements This service provides global changes that can be made based on the analysis and database work done for the cutovers.
Disaster Recovery This service provides duplicated programming in backup switches for key lines\remote modules.
Other Traffic studies/reports, customized reports, reconciling switch and service database information, producing telephone directory input, etc.
ATA’s automated cutover process virtually eliminates human error and accommodates last minute changes critical to keeping the customer and users satisfied with cutover performance.
Directory Number and Feature All set conversion information is automatically extracted from the original source switch, processed using predefined rules, converted and then transferred to a new target switch. The transferred information will include related blocking restrictions and hunt group information. Data can be loaded into the target switch for initial testing and updated on the target switch as needed. This allows service changes to continue to be implemented in the original switch until a short time before cutover, creating a short ‘freeze’ period.
Dialing Plan Conversion It is often desirable or even necessary to change the dialing plan during an expansion cutover. Examples include changing a block of converted numbers to fit into an organization’s new or existing dialing plan or changing the dialing plan from ‘5’ to ‘7’ digits. Special Feature Conversion This service automates the transfer of special features, such as directory number transfers, call forwarding, hotlines, warmlines, call waiting, voice mail, UCD groups, and special routing. Use of this service just before or just after cutover will ensure that the most recent status of all special features are transferred to the new switch. Trunking, Zone Blocking and Routing The transfer trunking and routing information from the source switch to the target switch can be automated. Also, creating and managing number routing on both the source and target switches can be an integral part of a multi-phased cutover approach.
