`Claim Element
`
`A method performed by a web
`enabled processing system
`including one or more web
`servers coupled to a tandem
`access controller serving as an
`intelligent interconnection
`between at least one packet
`network and a second network
`coupled to a particular PSTN
`tandem switch of a PSTN
`telecommunications network,
`wherein the second network is a
`network of PSTN tandem
`switches,

`
`“Rather, it redirects calls to subscribers. The
`TAC 10 provides intelligent interconnection
`between a calling party and a subscriber. The
`reader should keep in mind that although only
`one tandem switch 16 is shown in FIG. 1, the
`invention will apply equally well to a network
`of tandem switches, as shown in FIG. 2. FIG. 2
`also illustrates how the subscriber can make
`calls using voice over IP via a conventional
`digital telephone 21.
`
`[0037] FIG. l illustrates the preferred method
`for an authorized subscriber to modify the 3rd-
`party control criteria by means of the world
`wide web 22 (and web server 23) using an
`internet browser.”
`
`“Fig. 5 is a flowchart of actions taken by the
`TAC 10 in response to an inbound call (using
`the subscriber's public phone number) to the
`subscriber.”

`
`“As noted, open architecture platform 402
`can receive both voice and data traffic. This
`traffic can be received from any network
`node of a telecommunications carrier. A
`telecommunications carrier can include, for
`example, a LEC, a CLEC, an IXC, and an
`Enhanced Service Provider (ESP). In a
`preferred embodiment, this traffic is received
`from a network node which is, for example . .
`. a class 3/4 switch, such as AT 106.
`Alternatively, the network system can also be,
`for example, a CLEC, or other enhanced
`service provider (ESP), an international
`gateway or global point-of-presence (GPOP),
`or an intelligent peripheral. Accordingly,
`open architecture platform 402 integrates
`both voice and data traffic on a single
`platform.” 19:54-67.
`
`“If the call comprises data traffic, NAS bay
`902 will use modems to convert the incoming
`data call into a form suitable for a destination
`data network (e.g., PPP data packets) for

`“The Public Switched Telephone Network
`(PSTN) consists of a plurality of edge switches

`tandem switch network allows connectivity
`between all of the edge switches, and a

`
`transmission to other data nodes over open
`architecture platform 402. For example, the
`resulting data packets are transmitted over an
`Ethernet/WAN connection 903 (using an
`Ethernet/WAN protocol), in conjunction with
`TCP/IP. It would be apparent to one of skill
`in the art that alternative network architecture
`could be used, such as, for example, FDDI,
`SONET, ATM, etc.” 25:35-44.

`“It is important to note that this invention
`deals with the convergence of voice and data
`networks.” 25:9-10.
`
`“Definitions: packetized voice or voice over a
`backbone - One example of packetized voice
`is voice over internet protocol (VOiP). Voice
`over packet refers to the carrying of
`telephony or voice traffic over a data

`
`“EO 104 and AT 106 are part of a switching
`hierarchy. EO 104 is known as a class 5
`office and AT 106 is a class 3/4 office switch.
`Prior to the divestiture of the RBOCs from
`AT&T, an office classification was the
`number assigned to offices according to their
`hierarchical function in the U.S. public
`switched network (PSTN). An office class is
`a functional ranking of a telephone central
`office switch depending on transmission
`requirements and hierarchical relationship to
`other switching centers. A class 1 office was
`known as a Regional Center (RC), the highest
`level office, or the "office of last resort" to
`complete a call. A class 2 office was known
`as a Sectional Center (SC). A class 3 office
`was known as a Primary Center (PC). A class
`4 office was known as either a Toll Center
`(TC) if operators were present, or otherwise

`as a Toll Point (TP). A class 5 office was an
`End Office (EO), i.e., a local central office,
`the lowest level for local and long distance
`switching, and was the closest to the end
`subscriber. Any one center handles traffic
`from one or more centers lower in the
`hierarchy. Since divestiture and with more
`intelligent software in switching offices, these
`designations have become less firm.

`“FIG. 4 includes an overview of an enhanced
`telecommunications network 400 according
`to the present invention. This invention
`relates to the convergence of two types of
`networks, i.e., voice and data networks.
`Telecommunications network 400 provides a
`bypass connection from the ingress EO 104 (a
`class 5 switch) or from AT 106 (a class 3/4
`switch) to the called party 110 and ISP 112.

`[0033] The TAC 10 is connected to or inside
`the conventional PSTN tandem switch 16 such
`that calls may flow through the TAC 10 in the
`same manner as the existing PSTN tandem
`switch, except that additional 3rd party features
`are applied to the call. As is well known, PSTN
`tandem switches are exchanges that direct
`telephone calls (or other traffic) to central
`offices 17, 18 or to other tandem switches.
`Details of the operation of the existing phone
`network may be found in the publication
`entitled New Net SS7 Tutorial," by ADC
`Telecommunications, copyright 1999,
`incorporated herein by reference. Additional
`details may be found in the numerous books
`describing the PSTN.
`
`[0034] The PSTN tandem switch 16 directs a
`first call (from the calling party 20 to the
`subscriber's phone 14 using the subscriber's
`public phone number) to the TAC 10, which in
`turn places a second call, subject to 3rd-party
`control information, to the subscriber's "private"
`phone number without yet terminating the first
`call. The TAC 10 is connected within the
`subscriber's local service area so calls from
`TAC 10 to the subscriber do not incur a toll.
`
`When the subscriber 12 terminates (or answers)
`the second call, the TAC 10 terminates the first
`call and connects it to the second call, thereby
`
`international gateway or global point-of-
`presence (GPOP), or an intelligent peripheral.
`The connection is called a bypass connection
`because it bypasses the connections from the
`egress EO 108 to called party 110 and ISP
`112. In other words, for example, the
`facilities of the incumbent LEC (ILEC)
`terminating the call of originating caller 102
`are bypassed.” 19:22-37.
`
`“Calling party 914 is another party that can
`establish a data connection using a modem
`connected to a host computer. However,
`calling party 914, via its host computer, has
`the additional feature of providing voice over
`IP (VOIP) service over communications link
`944.” 26:9-14.
`
`“FIG. 1 is a block diagram providing an
`overview of a standard telecommunications
`network 100 providing local exchange carrier
`(LEC) services within a local access and
`transport area (LATA). Telecommunications
`network 100 provides a switched voice
`connection from a calling party 102 to a
`called party 110, as well as a data connection
`from calling party 102 to, for example, an
`Internet service provider (ISP) 112. Calling
`party 102 and called party 110 can be
`ordinary telephone equipment, key telephone
`systems, private branch exchanges (PBXs), or
`applications running on a host computer. ISP
`112 can in the alternative be, for example, a
`private data network. For example, calling

`connecting the calling party 20 to the subscriber
`12. Hence, the calling party essentially calls the
`TAC 10, using the subscriber's public phone
`number, and the TAC 10, after processing the
`call using the selected features, calls the
`subscriber, as appropriate, using the subscriber's
`private phone number and connects the two
`calls.”

`only one tandem switch 16 is shown in FIG. 1,

`
`“In step 1002 of FIG. 10A, the technique
`receives signaling information to set up data
`calls and voice calls from a calling party to a
`called party. In step 1004, the technique
`converts the signaling information into an
`open architecture protocol format. In step
`1006, data calls and voice calls are received
`at open architecture switch 502. In step 1008,
`the technique distinguishes between data calls
`and voice calls. In step 1010, the technique
`controls NASs, i.e., [tandem] NAS bays 504
`and [modem NAS bays] 514, using the open
`architecture protocol. In step 1012, the
`method terminates data calls to modems in a
`modem NAS bay, e.g., in modem NAS 514,

`When the subscriber 12 terminates (or answers)

`
`for conversion to a packetized data format for
`transmission to network nodes. Alternatively,
`in step 1012, a tunnel is established between
`the user and the destination data network. In
`step 1014, the method transmits voice calls to
`a voice switch for transmission to the called
`party.” 27:2-18.

`DMS switch, model DMS 500, available from
`NORTEL, Richardson, Tex., is used for

`“FIGS. 10B and 10C depict more detailed
`description of the technique outlined in FIG.

`inbound call flow into open architecture
`platform 402. An inbound call is where an
`incoming call (into the open architecture
`platform) is connected to a called party (for a
`voice connection) or an ISP (for a data
`connection).
`
`Referring to FIG. 10B, in step 1018 an
`originating caller 102 (shown in FIG. 1) gains
`access to LEC facilities. This is performed
`according to known methods as described
`with respect to FIG. 1. As one example,
`originating caller 102, using a telephone, can
`go off-hook to place a switched voice call to
`the LEC facilities. As another example,
`calling party 102 can use a host computer, in
`concert with a modem, to establish a data

`connecting the calling party 20 to the subscriber
`12. Hence, the calling party essentially calls the
`TAC 10, using the subscriber's public phone
`number, and the TAC 10, after processing the
`call using the selected features, calls the
`subscriber, as appropriate, using the subscriber's
`private phone number and connects the two
`calls.”

`
`“Until now, optional features were provided by
`the local service telephone company (telco)
`through the edge switch at the central office
`(CO). It was not possible to provide optional
`features through any other means. Control of
`these features was done through the first party
`(calling party) or the second party (called
`party), or worse yet, manually by calling the
`business office.
`
`[0007] In the past, numerous devices have been
`built that allow the connection of two lines
`
`“Alternatively, the connection can be
`established from calling party 102 to EO 104
`and then to AT 106, then over trunk 406 to
`open architecture platform 402, then over
`trunk 410 to called party.” 110. 20:18-21.

`“In step 1024, the LEC facilities perform a
`table lookup and then transmit the call to a
`facility (e.g., a class 4 AT switch or a class 5
`EO switch) that is connected to open

`together at an edge switch. These devices can
`be used to add features to a telephone network
`by receiving a call on one line and then dialing
`out on another line. The problem with these
`devices is that, because they are connected
`through an edge switch, transmission losses and
`impairments occur, degrading the overall
`connection. In addition, signaling limitations
`prevent full control, by the subscriber or the
`system, over the call.

`
`“The PSTN tandem switch 16 directs a first call
`(from the calling party 20 to the subscriber's
`phone 14 using the subscriber's public phone
`number) to the TAC 10, which in turn places a
`second call, subject to 3rd-party control
`information, to the subscriber's "private" phone
`number without yet terminating the first call.
`The TAC 10 is connected within the
`subscriber's local service area so calls from
`TAC 10 to the subscriber do not incur a toll.
`When the subscriber 12 terminates (or answers)
`the second call, the TAC 10 terminates the first
`call and connects it to the second call, thereby
`
`“Referring to FIG. 10C, in step 1030, the
`control server must determine whether the
`call is a data call or a voice call to take
`appropriate actions. Control server 510 looks
`up the called party number in internal or
`external database 516 to determine whether
`the call is a data call or a voice call. Based on
`the type of call, control server 510 indicates
`to control facilities (associated with tandem
`NAS bay 504) how to route the traffic.”
`29:44-51.
`
`“In step 1034, a data call over a given bearer
`channel (e.g., a DS0 channel) is time division

`connecting the calling party 20 to the subscriber
`12. Hence, the calling party essentially calls the
`TAC 10, using the subscriber's public phone
`number, and the TAC 10, after processing the
`call using the selected features, calls the
`subscriber, as appropriate, using the
`subscriber's private phone number and connects
`the two calls. The process is transparent to the
`parties... Rather, it redirects calls to subscribers.
`The TAC 10 provides intelligent
`interconnection between a calling party and a
`subscriber. The reader should keep in mind that
`although only one tandem switch 16 is shown in
`FIG. 1, the invention will apply equally well to
`a network of tandem switches, shown in FIG.
`2. FIG. 2 also illustrates how the subscriber can
`make calls using voice over IP via a
`conventional digital telephone 21.”

`
`termination at particular modems. The data
`call arriving over a given bearer channel on
`connection 406 (from AT 106) is assigned to
`a module on modem NAS bay 514. In other
`words, the incoming bearer channel is
`assigned to a given bay/module/line/channel
`(BMLC) going into modem NAS bay 514 to a
`terminating point. Table 32 illustrates an
`example message flow for this step.
`
`In step 1036, a modem performs the
`conversion (i.e., a modem in modem NAS
`bay 514 converts the call from one form into
`a form suitable for a destination data
`network.) For example, the call can be
`converted from one type of data signal (e.g., a
`PPP data signal) into another form of data,
`such as packets (e.g., IP data packets) for
`routing to another point such as an ISP.
`
`Step 1038 is the acceptance of the data call by
`the platform. As illustrated in Table 26, a
`message is sent from the control facilities of
`tandem NAS bay 504 to control server 510,
`indicating the inbound call is accepted by
`open architecture platform 402. Control
`server 510 then indicates an accepted data
`connection to SS7 GW 512, which in turn
`sends an address complete (ACM) message
`out over SS7 network 114. When homed EO
`104 is made aware of this condition, it plays a
`ringing signal for calling party 102, or more
`specifically, to the modem used by calling
`party 102. This indicates a connection is

`about to be established with a modem.” 30:4-
`35.
`
`“In step 1040, the call is connected between a
`modem on modem NAS bay 514 and the
`modem of calling party 102….. The call is
`routed between calling party 102 and another
`point, such as, an ISP as described with
`respect to FIG. 9A.” 30:36-37, 48-50.
`
`“Calling party 914 is another party that can
`establish a data connection using a modem
`connected to a host computer. However,
`calling party 914, via its host computer, has
`the additional feature of providing voice over
`IP (VOIP) service over communications link
`944.” 26:9-14.
`
`“Definitions: packetized voice or voice-- One
`example of packetized voice is voice over a
`backbone over internet protocol (VOIP).
`Voice over packet refers to the carrying of
`telephony or voice traffic over a data
`network, e.g. voice over frame, voice over
`ATM, voice over Internet Protocol (IP), over
`virtual private networks (VPNs), voice over a
`backbone, etc.” 12:50-56.
