Abstract

A method and system for providing a network which routes telephone calls to the dial-up access line of on-line data services, such as an Internet Service Provider. The calls are routed over, over data trunks to a circuit-switch that consolidates access to on-line data services. The data trunks are separate from trunks carrying normal voice telephone calls. At the originating office where the telephone call originates, the call is recognized as a call to a telephone number associated with the dial-up access telephone number of an on-line data service. A database selects a route over a data trunk to the terminating office having a circuit-switch that consolidates access to the on-line data services. The consolidation of access to on-line data services over segregated data trunks to a single circuit-switch reduces congestion in the network by relieving the network from handling a large volume of long duration telephone calls.

Claims

exact text as granted — not AI-modified
1 . A database for routing telephone calls directed to on-line computer data services from an originating central office to a terminating central office, the database comprising: 
 a routing table comprising a plurality of telephone numbers associated with dial-up access lines to on-line computer data services, a plurality point codes corresponding to a plurality of originating central offices, wherein each point code uniquely identifies one of the originating central offices, and a plurality of trunk route identifiers corresponding to a plurality of trunk routes for connecting the plurality of originating central offices with the terminating central office; and    service logic to identify a trunk route for connecting the originating central office with the terminating central office,    wherein the plurality of trunk routes are dedicated to carrying only data traffic.    
   
   
       2 . The database of  claim 1 , wherein the routing table is operative to identify the plurality of telephone numbers associated with dial-up access lines to on-line data services by a ten-digit NPA-NXX-XXXX.  
   
   
       3 . The database of  claim 1 , wherein the service logic is operative to identify the trunk route by identifying a ten-digit NPA-NXX-XXXX telephone number associated with the trunk route to the terminating central office.  
   
   
       4 . A network for routing telephone calls directed to on-line computer data services from an originating central office to a terminating central office, the network comprising: 
 a database in communication with the originating central office, the database including a routing table that includes: (i) a plurality of telephone numbers associated with dial-up access lines to on-line data services; and (ii) a plurality of point codes that correspond to a plurality of originating central offices, wherein each point code uniquely identifies one of the originating central offices, and the database being operative to identify telephone calls to on-line computer data services;    a data trunk for connecting the originating central office and the terminating central office, the data trunk being dedicated exclusively for carrying data transmissions; and    a circuit-switch at the terminating central office, the circuit switch being operative to connect the data trunk with the on-line data services.    
   
   
       5 . The system of  claim 4 , wherein the database is operative to identify telephone calls to on-line computer data services in response to an advanced intelligent network query.  
   
   
       6 . The system of  claim 4 , wherein the database is further operative to identify the data trunk for connecting the originating central office and the terminating central office.  
   
   
       7 . The system of  claim 4 , wherein the database is further operative to identify the data trunk for connecting the originating central office and the terminating central office by indexing a dialed telephone number and a point code identifying the originating central office in the routing table.  
   
   
       8 . The system of  claim 4 , wherein the circuit-switch consolidates access to on-line data services within a local access and transport area (LATA).  
   
   
       9 . The system of  claim 4 , further comprising a primary rate interface for connecting the circuit-switch with the on-line data services.  
   
   
       10 . The system of  claim 4 , further comprising a T1/DS1 line for connecting the circuit-switch with the on-line data services.  
   
   
       11 . The system of  claim 4 , wherein the data trunk comprises a T1 trunk line.  
   
   
       12 . The system of  claim 4 , wherein the circuit-switch is dedicated to receive only calls to on-line data services.  
   
   
       13 . A network for routing telephone calls directed to on-line computer data services from an originating central office to a terminating central office, the network comprising: 
 a database in communication with the originating central office, the database including a routing table that includes: (i) a plurality of telephone numbers associated with dial-up access lines to on-line data services; and (ii) a plurality of trunk route identifiers corresponding to a plurality of trunk routes for connecting a plurality of originating central offices with the terminating central office, and the database being operative to identify telephone calls to on-line computer data services;    a data trunk for connecting the originating central office and the terminating central office, the data trunk being dedicated exclusively for carrying data transmissions; and    a circuit-switch at the terminating central office, the circuit switch being operative to connect the data trunk with the on-line data services, wherein the circuit-switch is dedicated to receive only calls to on-line data services.    
   
   
       14 . The network of  claim 13 , wherein the database is operative to identify telephone calls to on-line computer data services in response to an advanced intelligent network query.  
   
   
       15 . The system of  claim 13 , wherein the database is further operative to identify the data trunk for connecting the originating central office and the terminating central office.  
   
   
       16 . The system of  claim 13 , wherein the database is further operative to identify the data trunk for connecting the originating central office and the terminating central office by indexing a dialed telephone number and a trunk route identifier in the routing table.  
   
   
       17 . The system of  claim 13 , wherein the circuit-switch consolidates access to on-line data services within a local access and transport area (LATA).  
   
   
       18 . The system of  claim 13 , further comprising a primary rate interface for connecting the circuit-switch with the on-line data services.  
   
   
       19 . The system of  claim 13 , further comprising a T1/DS1 line for connecting the circuit-switch with the on-line data services.  
   
   
       20 . The system of  claim 13 , wherein the data trunk comprises a T1 trunk line.
