`ABSTRACT
`An open architecture platform bypasses data from the facili
`ties of a telecommunications carrier, e.g. an incumbent local
`exchange carrier, by distinguishing between Voice and data
`traffic, and handling voice and data traffic separately. An SS7
`gateway receives and transmits SS7 signaling messages with
`the platform. When signaling for a call arrives, the SS7 gate
`way informs a control server on the platform. The control
`server manages the platform resources, including the SS7
`gateway, tandem network access servers (NASs) and modem
`NASs. A tandem NAS receives the call over bearer channels.
`The control server determines whether the incoming call is
`voice traffic or data traffic, by the dialed number, and instructs
`the tandem NAS how to handle the call. Voiced traffic is
`transmitted to a switch for transmission from the platform.
`Data traffic is terminated at a modem NAS, where it is con
`Verted into a form Suitable for a data network, Such as a private
`data network or an Internet services provider (ISP). The con
`verted data is sent by routers to the data network. The data
`network need not convert the data, as the function has already
`been provided by the platform. In lieu of a conversion, the
`modems can create a tunnel (a virtual private network)
`between a remote server and the data network.
