Intraswitch transition to new line support equipment
First Claim
1. A method for transferring service provided to subscriber lines by one set of line unit equipment coupled to a digital telecommunications switch to another set of line unit equipment coupled to said switch, said switch having a first data assignment table that includes a list of subscriber telephone numbers and, for each telephone number, the identity of a line unit port associated with said one set of line unit equipment and the states of subscriber selectable features associated with each of said telephone numbers, the method comprising the steps of:
- (a) creating a second data assignment table in said switch based on said first data assignment table wherein said telephone numbers and states of corresponding subscriber selectable features contained in said first table are stored in said second table;
(b) assigning in said second table a line unit port identification of one of said another set of line unit equipment for each telephone number;
(c) following steps (a) and (b), activating said second table and deactivating said first table to transfer said service, said active second table causing said subscriber lines to be serviced via said another set of line unit equipment.

Abstract
This invention is generally directed to minimizing the disruption of subscriber selectable features during the transfer of subscriber lines from a first line unit equipment to a second line unit equipment associated with a telecommunications switch. A second data assignment table which is based on a first data assignment table is utilized in conjunction with a digital telecommunications switch to facilitate an improved service transition when subscriber lines are to be transferred from a first type of line unit equipment to a second type of line unit equipment. The data assignment tables contain for each telephone number an identification of a line unit address utilized to support that telephone number and corresponding parameters which identify which customer selectable features are active. The second data table duplicates the parameter defining features in existence in the first table as of the time of creation of the second table, but substitutes different line unit addresses corresponding to the new line unit equipment for each telephone number to be supported. Upon a physical transition to the new equipment, the second data table is activated so that upon a resumption of service customers will have access to previously defined features as defined in the second table.

5. In a digital telecommunications switch having one set of line unit equipment coupled to subscriber lines, another set of line unit equipment capable of providing service to said subscriber lines, and means for storing a first data assignment table that includes a list of subscriber telephone numbers and, for each telephone number, the identity of a line unit port associated with said one set of line unit equipment and the states of subscriber selectable features associated with each of said telephone numbers, the improvement in transferring subscriber line service from said one set to said another set of line unit equipment comprising:
-
means for storing a second data assignment table in said switch based on said first data assignment table wherein said telephone numbers and states of corresponding subscriber selectable features contained in said first table are stored in said second table and wherein line unit port identifications of said another set of line unit equipment are assigned for each telephone number; microcomputer processing means operating under control of a program for activating said second table and deactivating said first table to transfer said service, said active second table causing said subscriber lines to be serviced via said another set of line unit equipment. - View Dependent Claims (6, 7, 8, 12, 13)

9. A method for transferring service provided to subscriber lines by one set of line unit equipment coupled to a digital telecommunications switch to another set of line unit equipment coupled to said switch, selectable hardware and features associated with subscriber telephone numbers in said switch, the method comprising the steps of:
-
(a) creating and storing in said switch a first data table that includes said subscriber telephone numbers and, for each telephone number, a first set of parameters that define which of said hardware and features are to be used for each telephone number; (b) utilizing said parameters in said first data table to control said features available for said telephone numbers; (c) creating and storing in said switch a second data table that includes for each of said telephone numbers a second set of parameters that define which of said hardware and features are to be used for each telephone number; (d) activating said second data table and deactivating said first data table whereby parameters defined in said second data table control features available for said telephone numbers. - View Dependent Claims (10, 14)
