Abstract
Telephone lines are moved from one or more switching modules (105 and 107) to one or more new switching modules (201) with minimal outage for customers whose lines are affected. Pseudo-lines are created (303) and the new switching module (201) and line data that supports customer features and routing of calls is programmed into the new switching module(s) (201). Connections are moved from the old module(s) (105 and 107) to the new module(s) (201), and the telephone numbers, i.e., routing information, is exchanged (309) between the modules in a single transaction.
Claims19
A method comprising the steps of:
- mapping a plurality of existing telephone numbers for a plurality of existing lines at a first switching module to a plurality of pseudo-telephone numbers;
- for each of the plurality of existing lines, creating a pseudo-line at a second switching module, yielding a plurality of pseudo-lines;
- generating a transaction that swaps the telephone numbers in the first switching module with the pseudo-telephone numbers in the second module;
- executing the transaction.
An apparatus comprising:
- a mapper, arranged and constructed to map a plurality of existing telephone numbers for a plurality of existing lines at a first switching module to a plurality of pseudo-telephone numbers;
- a line generator, arranged and constructed to create, for each of the plurality of existing lines, a pseudo-line at a second switching module, yielding a plurality of pseudo-lines;
- a transaction generator, arranged and constructed to generate a transaction that swaps the telephone numbers in the first switching module with the pseudo-telephone numbers in the second module;
- an execution device that executes the transaction.
A computer-readable signal bearing medium comprising:
- computer readable program code for mapping a plurality of existing telephone numbers for a plurality of existing lines at a first switching module to a plurality of pseudo-telephone numbers;
- computer readable program code for creating a pseudo-line at a second switching module for each of the plurality of existing lines, yielding a plurality of pseudo-lines;
- computer readable program code for generating a transaction that swaps the telephone numbers in the first switching module with the pseudo-telephone numbers in the second module;
- and
- computer readable program code for executing the transaction.
