Abstract

An intelligent network for providing access to an information network (80) has a number of central office switches (64, 82). Each central office switch (64, 82) is capable of receiving a call to a centrex telephone number and transmitting a query. A service control point (70) is coupled to the central office switches (64, 82) by a SS7 signal link (66). The service control point receives the query and transmits a response to the central office switch (64, 82). A hub switch (75) is coupled to the central office switches (64, 82) and receives the call. The hub switch (75) contains a digital trunk service (76) that combines the call with a number of other calls to form a data stream. The data stream is then transmitted to an information network node (80).

Claims

1. A method of providing access to an information network, comprising the steps of:

(a) selecting a plurality of centrex lines;

(b) forwarding a plurality of calls, placed to one of the plurality of centrex lines, to a hub switch;

(c) combining the plurality of calls to form a data stream;

(d) transmitting the data stream to an information network access node.

2. The method of claim 1, wherein step (b) further includes the steps of:

(b1) interrupting a call processing at a central office switch;

(b2) receiving a routing instruction.

3. The method of claim 2, further including the step of:

(b3) receiving a billing instruction.

4. The method of claim 2, wherein step (b2) further includes the steps of:

(i) transmitting a query to a service control point;

(ii) receiving a response from the service control point;

(iii) routing one of the plurality of calls based on the response.

5. The method of claim 1, wherein step (b) further includes the step of switching the plurality of calls at the hub switch.

6. The method of claim 1, wherein step (c) includes the step of routing the plurality of calls to a digital trunking service.

7. The method of claim 6, wherein the step digital trunking service places the data stream in an integrated service digital network primary rate interface service format.

8. The method of claim 1, wherein step (d) further includes the step of selecting a dedicated trunk.

9. The method of claim 1, further including the step of measuring a line-time usage of the plurality of calls.

10. An intelligent network for providing access to an information network comprising:

a plurality of central office switches capable of receiving a call to one of a plurality of centrex telephone numbers and transmitting a query;

a service control point coupled to the plurality of central office switches by a SS7 signal link, the service control point receiving the query and transmitting a response;

a hub switch coupled to the plurality of central office switches, the hub switch receiving the call to one of the plurality of centrex telephone lines;

a digital trunk service in the hub switch combining the call with a plurality of other calls to form a data stream; and

an information network node coupled to the digital trunk service and receiving the data stream.

11. The intelligent network of claim 10, further including a plurality of call forwarding paths connecting the plurality of central office switches to the hub switch.

12. The intelligent network of claim 10, further including a digital trunk coupling each of the plurality of central offices to the hub switch, wherein the call to one of the plurality of centrex telephone numbers is carried by the digital trunk.

13. The intelligent network of claim 10, wherein the digital trunking service places the data stream in a twenty four channel 1.544 Mbps format.

14. The intelligent network of claim 10, wherein the digital trunking service placed the data stream in an integrated service digital network primary rate interface service format.

15. The intelligent network of claim 10, further including a dedicated trunk connecting the hub switch to the information network node.

16. The intelligent network of claim 10, wherein the hub switch measures a centum call seconds of the data stream.

17. A computer-readable storage medium containing computer-readable instructions that when executed by an advanced intelligent network, the advanced intelligent network performs the following steps:

(a) selects a plurality of centrex telephone numbers;

(b) interrupts a call at a central office switch when one of the plurality of centrex telephone numbers is called;

(c) transmits a query to a service control point;

d) receives a response from a service control point;

(e) combines the call with a plurality of other calls placed to one of the plurality of centrex telephone numbers to from a data stream; and

(f) transmits the data stream to an information network access point.

18. The computer-readable storage medium of claim 17, further including the step of:

(h) measuring a usage of the data stream.

19. The computer-readable storage medium of claim 17, wherein step (g) further includes the step of selecting a dedicated trunk.

20. The computer-readable storage medium of claim 17, wherein step (d) further includes the step of counting and storing an origination group.
