System and method for bypassing data from egress facilities
First Claim
1. A system for bypassing egress facilities of a telecommunications carrier, the system comprising:
- a receiving means for receiving voice calls;
a distinguishing means for determining whether received calls are data calls or voice calls based on signaling information associated with the calls; and
a converting means for converting calls determined by the distinguishing means to be data calls into a format usable by an open architecture platform, wherein the distinguishing means and the converting means communicate via the open architecture platform, wherein;
said convening means comprises at least one network access server for terminating said incoming data calls to modems, wherein said modems convert said incoming data calls from a first format to a second format; and
said receiving means and said distinguishing means comprise a gateway hosting a first application program for handling signaling information, and a control server for controlling said gateway and said at least one network access server.

Abstract
An open architecture platform bypasses data from the facilities 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 gateway 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 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.

4. A method for bypassing data calls from egress facilities of a telecommunications carrier, the method comprising the steps of:
-
establishing a call with an open architecture telecommunications system; determining whether said call is a voice call or a data call by querying a table comprising called party numbers and respective termination points corresponding to the called party numbers; and if said call is a data call, terminating said call onto a network access server for termination processing and converting signaling information associated with the call into a format used by the open architecture telecommunications system, wherein establishing a call with said telecommunications system comprises; receiving signaling information to set up a call coming into said open architecture telecommunications system; informing a control server that a call has arrived on said open architecture telecommunications system; and receiving said call at said open architecture telecommunications system. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 20)

17. A method for bypassing facilities of a circuit-switched based telecommunications carrier, the method comprising:
-
receiving a call comprising media and signaling information; determining whether the call is a data call or a voice call by querying a table comprising called party numbers and respective termination points corresponding to the called party numbers; and if the call is determined to be a data call, directing the call away from the circuit-switched based telecommunications carrier to a packet-based communication network. - View Dependent Claims (18, 19)
