`
`“A method and apparatus are disclosed for
`interconnecting a circuit-switched telephone
`network and a packet-switched data network
`for communication among them. A signaling
`trunk of a circuit-switched telephone network
`is coupled to a signaling access server that is
`also coupled to a signaling, management and
`control network. One or more voice trunks
`of the telephone network are coupled to one
`or more network access servers, which are
`also coupled to the control network to thereby
`receive instructions from the signaling access
`server . . . The signaling access server can
`receive call setup messages and other
`messages in standard telephone network
`protocol formats and convert them into call
`setup messages in a special protocol for
`communications between the signaling access
`server and the network access servers. The
`signaling access server can instruct the
`network access servers to establish a call,
`containing voiceband information such as
`modem-based data calls, from the voice

`public switched telephone network and the

`
`“[T]he present invention, which comprises, in
`one aspect a telecommunications apparatus
`that can interconnect a circuit-switched
`telephone network and a packet-switched
`data network to enable communication
`among the networks. The apparatus has a first
`server coupled to a signaling trunk of the
`telephone network to interchange call
`signaling messages therewith, and coupled to
`a control network. One or more second
`servers each are coupled to a voice trunk of
`the telephone network to communicate voice-
`band information thereon, and coupled to
`receive instructions from the first server
`through the control network, and coupled to
`the data network to communicate data
`thereon. First and second software
`components are executed by and controlling
`the first server and the second server,
`respectively, and interact cooperatively to
`establish a call originating in the telephone
`network and containing voiceband
`information and terminating in the
`data network, based on call signaling
`information received from the signaling trunk
`by the first server.” 2:28-45

`“The present disclosure will describe an
`invention which, in one embodiment,
`provides a distributed system for
`interconnecting one or more Network Access
`Servers, which are coupled to a data network
`such as the Internet, to a circuit switched
`Time Division Multiplexing telephone
`network that uses Signaling System 7
`protocols for signaling. The interconnection
`is achieved, in part, using a protocol
`converter that is configured as a Signaling
`Access Server ("SAS") and that interworks
`with a Network Access Server ("NAS").
`"Interworks" means, for example, that the
`Signaling Access Server commands and
`manages the Network Access Servers using a
`signaling and control network; it is also
`possible for the NAS to place outgoing calls
`through the SAS to an SS7 network. 4:5-5:4

`“FIG. 1A is a block diagram of the logical

`comprises one or more Network Access
`Servers 118, located at one or more service
`provider points of presence. Each Network
`Access Server 118 is coupled to and provides
`termination for a pre-determined number of
`voice network trunks 10. Each Network
`Access Server 118 has a first Internet
`Protocol network interface coupled to a data
`network backbone 14 and a second Internet

`[T]he software components comprise

`steps of receiving a call setup message from
`the telephone network that contains a master
`telephone number; sending a responsive
`message to the telephone network that
`contains a specific telephone number
`associated with one of the second servers;
`and setting up a call between the telephone
`network and one of the second servers that is
`associated with the specific telephone
`number. A related feature is that the software
`components further comprise instructions
`which, when executed by the first server,
`cause the first server to carry out the steps of
`receiving a call offer message from the
`telephone network that contains the specific
`telephone number.” 3:18-31
`
`“On the other hand, the originating protocol
`adapter 1412 may not be able to find the
`corresponding call instance 1420, for
`example, because the message is the first
`message pertaining to a call.” 13:27-31

`produced by switches or other network

`
`elements, because Signaling Access Server
`112 has complete access to all signaling
`messages passing through it.” 19:6-10
`
`“FIG. 7A specifically shows messages
`communicated for normal setup of a call,
`originated by the public switched telephone
`network as represented by SS7 trunks 20,
`without alerting, and without continuity
`testing. Initially the Signaling Access Server
`112 is in the Idle state 702. The network 20
`delivers an Initial Address Message 704 to
`the Signaling Access Server 112. Signaling
`Access Server 112 sends a Setup message
`706 to one of its associated Network Access
`Servers 118. The Network Access Server 118
`responds with a Call Processing message 708.
`Signaling Access Server 112 interprets the
`Call Processing message as an affirmative
`acknowledgment and, accordingly, Signaling
`Access Server 112 sends an acknowledgment
`message 710 to network 20.
`
`Network Access Server 118 then establishes a
`call connection. For example, in the ISP dial-
`up context, Network Access Server 118 may
`select a modem or other connecting device at
`the premises of an Internet Service Provider.
`When the connection has been established,
`Network Access Server 118 sends a Connect
`message 712 to Signaling Access Server 112.
`The Signaling Access Server 112 responds by
`sending an Answer message 714 to network
`20. Conventionally, the Answer message
`
`12
`
`Bright House Networks – Ex. 1068, Page 12
`
`

`

`
`
`
`
`indicates that a called party has answered a
`telephone or other network element, however,
`in this context the Answer message indicates
`that call setup is successful and a connection
`has been established. Signaling Access Server
`112 then enters a Conversation state 716 in
`which a voice conversation or data
`conversation occurs.” 38:12-40.
`
`“SSP 224 analyzes the information in the
`message, determines that Signaling Access
`Server 112 is associated with the dialed

`“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.
`In the past, numerous devices have been built
`that allow the connection of two lines 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.
`A preferred embodiment of the inventive system
`described herein connects at the tandem, thereby
`eliminating these problems.”

`“Fig. 1 uses a public internet portal connected
`via a data link to the TAC 10 or other interface
`system. As a registered subscriber, a user logs
`onto the portal (Fig.

`make additions or changes to features such as
`speed calling, call forwarding, selection of such
`descriptors as time of day, busy status, caller ID
`status, etc.”

`“Fig. 1 illustrates the preferred method for an
`authorized subscriber to modify the 3rd-party
`control criteria by means of the world wide web

`who is registered and has logged- in with
`appropriate security and password controls. The
`subscriber 12 interacts with the web 22 via the
`Internet to quickly and easily specify the
`enhanced 3rd-party call control features. Web

`“In the past, numerous devices have been built
`that allow the connection of two lines 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.”
`
`“In addition to these toll services, there are edge
`devices that perform some of the same services.
`Edge devices such as phones and PBXs that
`include voice mail, inter-active voice response,
`call forwarding, speed calling, etc., have been
`used to provide additional call control. These
`devices allow the phone user direct control over
