`ABSTRACT
`(57)
`An Open architecture platform bypasses data from the facili_
`ties of a telecommunications carrier, eg an incumbent local
`exchange carrier, by distinguishing betWeen voice and data
`traffic, and handling voice and data traf?c separately. An SS7
`gateWay receives and transmits SS7 signaling messages With
`the platform. When signaling for a call arrives, the SS7
`gateWay informs a control server on the platform. The
`g‘ggml Server margages the platform resources’ inglg‘éing thg
`gateway’ tan em networ “C855 Servers (
`5) an
`modem NASs. A tandem NAS receives the call over bearer
`channels. The control server determines Whether the incom
`ing call is voice traf?c or data traf?c, 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 converted into a form suitable for a data network, such
`as a private data netWork or an Internet services provider
`(ISP). The converted 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
