Method and network for providing access to an information network

摘要

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).
