A method of operating a virtual private network includes the steps of: (a) dialing a custom number; (b) receiving the custom number at a switch () of a first carrier; (c) routing the call to a switch () of a second carrier based on having received the custom number; and (d) when the call to the switch () of the second carrier includes a plain old telephone number translation of the customer number, routing the call over the second carrier to a service switching point () of a third carrier.

Method of operating a virtual private network

A method of routing interLATA network traffic includes the steps of receiving a number of dialed digits at a first service switching point () in a first virtual network (). Then a query is sent to a service control point (). When the dialed digits result in the call to a facility () in a second virtual network () connected to the first virtual network () by a tie line (), the call is routed to a hub service switching point () in the second virtual network () over the tie line ().

Method of routing interLATA network traffic

An intelligent network for providing access to an information network () has a number of central office switches (). Each central office switch () is capable of receiving a call to a centrex telephone number and transmitting a query. A service control point () is coupled to the central office switches () by a SS7 signal link (). The service control point receives the query and transmits a response to the central office switch (). A hub switch () is coupled to the central office switches () and receives the call. The hub switch () contains a digital trunk service () 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 ().

Method and network for providing access to an information network

A method of operating a virtual private network includes the steps of: (a) dialing a custom number; (b) receiving the custom number at a switch ( ) of a first carrier; (c) routing the call to a switch ( ) of a second carrier based on having received the custom number; and (d) when the call to the switch ( ) of the second carrier includes a plain old telephone number translation of the customer number, routing the call over the second carrier to a service switching point ( ) of a third carrier.

A method of routing interLATA network traffic includes the steps of receiving a number of dialed digits at a first service switching point ( ) in a first virtual network ( ). Then a query is sent to a service control point ( ). When the dialed digits result in the call to a facility ( ) in a second virtual network ( ) connected to the first virtual network ( ) by a tie line ( ), the call is routed to a hub service switching point ( ) in the second virtual network ( ) over the tie line ( ).

Method of routing interlata network traffic

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

A method of operating a virtual private network includes the steps of: (a) dialing a custom number; (b) receiving the custom number at a switch (20) of a first carrier; (c) routing the call to a switch (18) of a second carrier based on having received the custom number; and (d) when the call to the switch (18) of the second carrier includes a plain old telephone number translation of the customer number, routing the call over the second carrier to a service switching point (26) of a third carrier.

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).

A method of aggregating calls includes receiving a group of dialed digits at a service switching point (52). The service switching point (52) determines if an access code is present. When the access code is present, the service switching (52) transmits an information analyzed query (54) to a switching control point (56). The service switching point (52) then receives an analyze route message (60) from the switching control point (56). The service switching point (52) then routes a call to a hub service switching point (58).

Method of aggregating a plurality of network traffic

A method using an advanced intelligent network to seamlessly connect a plurality of virtual networks includes the steps of: (a) Receiving a number of dialed digits at a first service switching point in a first local access and transport area (10); (b) When the first service switching point is determined to be a hub service switching point (22), sending a query to a service control point (24); (d) Determining if the dialed digits require an access to a private networks interLATA call; and (e) When the dialed digits require access to the private networks interLATA call, routing the call over a tie line (40) to a second hub service switching point (34) in a second local access and transport area (26).
