Abstract:
A method of providing for customer selection of a trunk group selection algorithm for use in a public network switching center comprising the steps ofmaintaining a time of day and day of week clock in a memory of said public network switching center, maintaining a first table of a plurality of trunk group selection algorithms in said public network switching center memory, permitting a customer to access said first table of trunk group selection algorithms in said public network switching center memory, receiving customer data defining a preferred trunk group selection algorithm for a first period of time and a second, different trunk group selection algorithm for a different period of time than said first period of time, maintaining said first table with said customer preferred and different trunk group selection algorithms for the first and different periods of time in said public network switching center memory, indexing by a customer identification code said first table with said customer preferred and different trunk group selection algorithms for said first and second periods of time in said public network switching center memory, maintaining a plurality of customer identification codes, for different customers, in said first table with said customer preferred and different trunk group selection algorithms for said first and different periods of time in said public network switching center memory, maintaining a second table of a plurality of customer identification codes, for different customers, in said public network switching center memory, indexing by a routing number said second table with said customer identification codes, receiving a dialed telephone number from a calling party, translating said dialed telephone number into a routing number, accessing said second table with said plurality of routing numbers, determining a customer identification code for a particular customer from the routing number, accessing said first table with said customer preferred and different trunk group selection algorithms for said first and different periods of time in said public network switching center memory indexed by customer identification code, determining a current time of day and day of week in order to select a customer preferred trunk group selection algorithm in accordance with one of said first and different periods of time, matching a customer preferred trunk group selection algorithm with the customer identification code in response to the current time of day and day of week, in accordance with a selected customer preferred trunk group selection algorithm, selecting a trunk group, and utilizing said selected customer preferred trunk group selection algorithm for delivery of calls to said particular customer.
