Abstract
A new architecture capable of utilizing the existing twisted pair interface between customer premises equipment and an associated serving local switching office is used to provide a vast array of new services to customers. Using an intelligent services director (ISD) at the customer services equipment as an interface for the equipment to an existing twisted cable pair and a facilities management platform (FMP) at the serving local switching office as an interface to various networks and service opportunities, new services such as simultaneous, multiple calls (voice analog or digital), facsimile, Internet traffic and other data can be transmitted and received over the twisted cable pair by using digital subscriber loop transmission schemes. The new services include but are not limited to videophone, utility meter reading and monitoring, broadcasting and multicasting. The architecture provides for fault-tolerant, transparent interaction of components and services and supports a variety of standards for each level of the open systems interconnection layers and layers of TCP/IP. The FMP connects electronically or optically to the public switched telephone network, Internet backbone, a private Intranet as well as other possible network connections.
Description




FIELD OF THE INVENTION




This invention discloses an architecture for supporting increased bandwidth to customer premises equipment allowing for increased services including videophone, analog and digital voice traffic, facsimile, voice mail, Internet traffic, and automated home services relating to meter reading, security, and energy management.




BACKGROUND




As deregulation of the telephone industry continues and as companies prepare to enter the local telephone access market, there is a need to offer new and innovative services that distinguish common carriers from their competitors. This cannot be accomplished without introducing new local access network architectures that will be able to support these new and innovative services.




Conventionally, customer premises telephone and/or data connections contain splitters for separating analog voice calls from other data services such as Ethernet transported over digital subscriber line (DSL) modems. Voice band data and voice signals are sent through a communications switch in a central or local office to an interexchange carrier or Internet service provider. DSL data is sent through a digital subscriber loop asynchronous mode (DSLAM) switch which may include a router. The DSLAM switch connects many lines and routes the digital data to a telephone company's digital broadband switch.




A major problem with this configuration is that as the interexchange carriers attempt to penetrate the local telephone company's territory, they must lease trunk lines from the local telephone company switch to the interexchange company's network for digital traffic. Furthermore, the Internet service provider must lease a modem from the local phone company in the DSLAM switch and route its data through the local phone company's digital broadband switch. Thus, the local phone company leases and/or provides a significant amount of equipment, driving up the cost of entry for any other company trying to provide local telephone services and making it difficult for the interexchange companies to differentiate their services. Furthermore, since DSL modem technology is not standardized, in order to ensure compatibility, the DSL modem provided by the local telephone company must also be provided to the end user in the customer premises equipment (CPE). Additionally, since the network is not completely controlled by the interexchange companies, it is difficult for the interexchange companies to provide data at committed delivery rates. Any performance improvements implemented by the interexchange companies may not be realized by their customers, because the capabilities of the local telephone company equipment may or may not meet their performance needs. Thus, it is difficult for the interexchange companies to convince potential customers to switch to their equipment or to use their services. These factors ensure the continued market presence of the local telephone company.




As part of this system, there is a need for improved architectures, services and equipment utilized to distinguish the interexchange companies' products and services. The existing copper twisted pair infrastructure limits the number of users on the twisted pair and the bandwidth transmitted. A method for expanding the number of simultaneous users and the bandwidth without replacing the existing twisted pair infrastructure is desired. In increasing the bandwidth and the number of simultaneous services transmitted over a single twisted pair will allow service providers an opportunity to expand and enhance services into consumers' homes and business operations while minimizing the incremental costs associated with initiating enhanced, new services.




In the process of providing enhanced, new services, it is desired for the service provider to offer fault tolerant, transparent interfaces for the user. Because of the need to keep costs minimized flexibility for using existing hardware and software systems is important. Therefore, it is also desired that the fault tolerant services offered be flexible to interface across multiple lines of hardware and various versions of software.




SUMMARY OF THE INVENTION




In order to provide an improved network it is desirable for the interexchange companies to have access to at least one of the twisted-pair lines or alternate wireless facility connecting each of the individual users to the local telephone network before the lines are routed through the conventional local telephone network equipment. It is preferable to have access to these lines prior to the splitter and modem technology offered by the local service providers. By having access to the twisted-pair wires entering the customer's premises, interexchange companies can differentiate their services by providing higher bandwidth, improving the capabilities of the customer premises equipment, and lowering overall system costs to the customer by providing competitive service alternatives.




The new architecture may utilize a video phone and/or other devices to provide new services to an end user; an intelligent services director (ISD) disposed near the customer's premises for multiplexing and coordinating many digital services onto a single twisted-pair line; a facilities management platform (FMP) disposed in the local telephone network's central office or DLC vault for routing data to an appropriate interexchange company network; and a network server platform (NSP) coupled to the FMP for providing new and innovative services to the customer and for distinguishing services provided by the interexchange companies from those services provided by the local telephone network.




The overall architecture of the system includes a hybrid optical fiber/twisted pair infrastructure functionally coupling the customer premises equipment to the facilities management platform by twisted pair operating xDSL technology. The utilization of xDSL technology increases the bandwidth to the customer premises equipment and allows for the offering of simultaneous services along the same twisted pair.




The facilities management platform is functionally coupled to a communication network and is supported by a network server platform. Typically, the facilities management platform is located at the local office, while the network server platform is located in a separate location due to space limitations, regulator considerations and/or costs at the local office. The architecture provides variable bandwidth channels, depending on the service requested by the subscriber, and may be dynamically adapted for providing requested services in both directions of transmission. Voice and data are intelligently multiplexed in order to maximize the available bandwidth of the twisted pair.




The facilities management platform supports both fiber and wire connections into the local telephone company's communication network, cable television network, Internet service provider's network or into a wireless communication's network.

Referring to

FIG. 1

, a first exemplary communication network architecture employing a hybrid fiber, twisted-pair (HFTP) local loop


1


architecture is shown. An intelligent services director (ISD)


22


may be coupled to a central office


34


via a twisted-pair wire, hybrid fiber interconnection, wireless and/or other customer connection


30


, a connector block


26


, and/or a main distribution frame (MDF)


28


. The ISD


22


and the central or local office


34


may communicate with each other using, for example, framed, time division, frequency-division, synchronous, asynchronous and/or spread spectrum formats, but in exemplary embodiments uses DSL modem technology. The central office


34


preferably includes a facilities management platform (FMP)


32


for processing data exchanged across the customer connection


30


. The FMP


32


may be configured to separate the plain old telephone service (POTS) from the remainder of the data on the customer connection


30


using, for example, a tethered virtual radio channel (TVRC) modem (shown in FIG.


4


A). The remaining data may be output to a high speed backbone network (e.g., a fiber optic network) such as an asynchronous transfer mode (ATM) switching network. The analog POTS data may be output directly to a public switch telephone network (PSTN)


46


, and/or it may be digitized, routed through the high speed backbone network, and then output to the PSTN


46


.




The FMP


32


may process data and/or analog/digitized voice between customer premise equipment (CPE)


10


and any number of networks. For example, the FMP


32


may be interconnected with a synchronous optical network (SONET)


42


for interconnection to any number of additional networks such as an InterSpan backbone


48


, the PSTN


46


, a public switch switching network (e.g. call setup SS


7


-type network


44


), and/or a network server platform (NSP)


36


. Alternatively, the FMP


32


may be directly connected to any of these networks. One or more FMPs


32


may be connected directly to the high speed backbone network (e.g., direct fiber connection with the SONET network


42


) or they may be linked via a trunk line (e.g., trunks


40


or


42


) to one or more additional networks.




The NSP


36


may provide a massive cache storage for various information that may be provided across the SONET net


42


to the FMP


32


and out to the ISD


22


. The NSP


36


and the FMP


32


may collectively define an access network server complex


38


. The NSP


36


may be interconnected with multiple FMPs


32


. Furthermore, each FMP


32


may interconnect with one or more ISDs


22


. The NSP


36


may be located anywhere but is preferably located in a point-of-presence (POP) facility. The NSP


36


may further act as a gateway to, for example, any number of additional services.




The ISD


22


may be interconnected to various devices such as a videophone


130


, other digital phones


18


, set-top devices, computers, and/or other devices comprising the customer premise equipment


10


. The customer premise equipment may individually or collectively serve as a local network computer at the customer site. Application applets may be downloaded from the NSP


36


into some or all of the individual devices within the customer premise equipment


10


. Where applets are provided by the NSP


36


, the programming of the applets may be updated such that the applets are continually configured to the latest software version by the interexchange carrier. In this way, the CPE


10


may be kept up to date by simply reloading updated applets. In addition, certain applets may be resident on any of the CPE


10


. These resident applets may be periodically reinitialized by simply sending a request from, for example, a digital phone


18


and/or a videophone


130


to the FMP


32


and thereafter to the NSP


36


for reinitialization and downloading of new applets. To ensure widespread availability of the new features made possible by the present architecture, the customer premise equipment may be provided to end users either at a subsidized cost or given away for free, with the cost of the equipment being amortized over the services sold to the user through the equipment.




Referring to

FIG. 2

, the ISD


22


may connect with a variety of devices including analog and digital voice telephones


15


,


18


; digital videophones


130


, devices for monitoring home security, meter reading devices (not shown), utilities devices/energy management facilities (not shown), facsimile devices


16


, personal computers


14


, cable television terminals (not shown), media player/recorders (not shown) and/or other digital or analog devices. Some or all of these devices may be connected with the ISD


22


via any suitable mechanism such as a single and/or multiple twisted-pair wires and/or a wireless connection. For example, a number of digital devices may be multi-dropped on a single twisted-pair connection. Similarly, analog phones and other analog devices may be multi-dropped using conventional techniques.




The ISD


22


may be located within the home/business or mounted exterior to the home/business. The ISD


22


may operate from electrical power supplied by the local or central office


34


and/or from the customer's power supplied by the customer's power company. Where the ISD


22


includes a modem, it may be desirable to power the ISD


22


with supplemental power from the home in order to provide sufficient power to enable the optimal operation of the modem.




As shown in

FIG. 2

, in some embodiments the ISD


22


may include a controller


100


which may have any of a variety of elements such as a central processing unit


102


, a DRAM


103


, an SRAM


104


, a ROM


105


and/or an Internet protocol (IP) bridge router


106


connecting the controller


100


to a system bus


111


. The system bus


111


may be connected with a variety of network interface devices


110


. The network interface devices


110


may be variously configured to include an integrated services digital network (ISDN) interface


113


, an Ethernet interface


119


(e.g., for 28.8 kbps data, 56 kbps data, or ISDN), an IEEE 1394 “fire wire” interface


112


(e.g., for a digital videodisc device (DVD)), a TVRC modem interface


114


(e.g., for a digital subscriber line (DSL) modem), a residential interface


114


, (e.g., standard POTS phone systems such as tip ring), a business interface


116


(e.g., a T


1


line and/or PABX interface), a radio frequency (RF) audio/video interface


120


(e.g., a cable television connection), and a cordless phone interface


123


(e.g., a 900 MHZ transceiver). Connected to one of the network interfaces and/or the system bus


111


may be any number of devices such as an audio interface


122


(e.g., for digital audio, digital telephones, digital audio tape (DAT) recorders/players, music for restaurants, MIDI interface, DVD, etc.), a digital phone


121


, a videophone/user interface


130


, a television set-top device


131


and/or other devices. Where the network interface is utilized, it may be desirable to use, for example, the IEEE 1394 interface


112


and/or the Ethernet interface


119


.




A lifeline


126


may be provided for continuous telephone service in the event of a power failure at the CPE


10


. The lifeline


126


may be utilized to connect the ISD


22


to the local telecommunications company's central office


34


and, in particular, to the FMP


32


located in the central office


34


.




The ISD may be variously configured to provide any number of suitable services. For example, the ISD


22


may offer high fidelity radio channels by allowing the user to select a particular channel and obtaining a digitized radio channel from a remote location and outputting the digital audio, for example, on audio interface


122


, video phone


130


, and/or digital phones


121


. A digital telephone may be connected to the audio interface


122


such that a user may select any one of a number of digital audio service channels by simply having the user push a digital audio service channel button on the telephone and have the speaker phone output particular channels. The telephone may be preprogramed to provide the digital audio channels at a particular time, such as a wake up call for bedroom mounted telephone, or elsewhere in the house. The user may select any number of services on the video phone and/or other user interface such as a cable set-top device. These services may include any number of suitable services such as weather, headlines in the news, stock quotes, neighborhood community services information, ticket information, restaurant information, service directories (e.g., yellow pages), call conferencing, billing systems, mailing systems, coupons, advertisements, maps, classes, Internet, pay-per-view (PPV), and/or other services using any suitable user interface such as the audio interface


122


, the video phone/user interface


130


, digital phones,


121


and/or another suitable device such as a settop device


131


.




In further embodiments, the ISD


22


may be configured as an IP proxy server such that each of the devices connected to the server utilizes transmission control protocol/Internet protocol (TCP/IP) protocol. This configuration allows any device associated with the ISD to access the Internet via an IP connection through the FMP


32


. Where the ISD


22


is configured as an IP proxy server, it may accommodate additional devices that do not support the TCP/IP protocol. In this embodiment, the ISD


22


may have a proprietary or conventional interface connecting the ISD


22


to any associated device such as to the set top box


131


, the personal computer


14


, the videophone


130


, the digital telephone


18


, and/or some other end user device.




In still further embodiments, the ISD


22


may be compatible with multicast broadcast services where multicast information is broadcast by a central location and/or other server on one of the networks connected to the FMP


32


, e.g., an ATM-switched network. The ISD


22


may download the multicast information via the FMP


32


to any of the devices connected to the ISD


22


. The ISD


22


and/or CPE


10


devices may selectively filter the information in accordance with a specific customer user's preferences. For example, one user may select all country music broadcasts on a particular day while another user may select financial information. The ISD


22


and/or any of the CPE


10


devices may also be programmed to store information representing users' preferences and/or the received uni-cast or multicast information in memory or other storage media for later replay. Thus, for example, video clips or movies may be multicast to all customers in the community with certain users being preconfigured to select the desired video clip/movie in real time for immediate viewing and/or into storage for later viewing.

Referring to

FIG. 4A

, the FMP


32


may coordinate the flow of data packets, separate voice signals from other signals, perform line monitoring and switching functions, and/or convert between analog and digital signals. The FMP


32


may process data sent from the CPE


10


to the central or local office


34


by separating and reconstructing analog voice signals, data, and control frames. The FMP


32


may process data sent from the central or local office


34


to the CPE


10


by separating control messages from user information, and configure this information into segments for transport across the digital subscriber loop. The FMP


32


may also terminate the link layer associated with the digital subscriber loop.




In some embodiments, the FMP


32


may include an access module


70


and a digital loop carrier


87


. The access module


70


may include a line protector


71


, a cross-connector


73


, a plurality of TVRC modems


80


, a plurality of digital filters


82


, a controller multiplexer


84


, and/or a router and facilities interface


86


. The digital loop carrier


87


may include a plurality of line cards


96


, a time domain multiplexing (TDM) multiplexor (MUX)


88


, a TDM bus


90


, a controller


92


, and/or a facilities interface


94


.




During normal operations, digital signals on the customer connection


30


(e.g., twisted-pair lines) containing both voice and data may be received by the TVRC modems


80


via the line protector


71


and the cross-connector


73


. Preferably, the line protector


71


includes lightning blocks for grounding power surges due to lightning or other stray voltage surges. The TVRC modems


80


may send the digital voice and/or data signals to the controller multiplexor


84


and the digital filters


82


. The digital filters


82


may separate the voice signals from the digital data signals, and the controller multiplexor


84


may then multiplex the voice signals and/or data signals received from the digital filters


82


. The controller multiplexor


84


may then send multiplexed voice signals to the TDM MUX


88


and the data signals to the router and facilities interface


86


for transmission to one or more external networks. The TDM MUX


88


may multiplex the voice signals from the controller multiplexor


84


and/or send the voice signals to the TDM bus


90


, which may then send the digital voice signals to the controller


92


and then to the facilities interface


94


for transmission to one or more external networks. Both the router and facilities interface


86


and the facilities interface


94


may convert between electrical signals and optical signals when a fiber optic link is utilized.




When there is a failure of the digital data link (e.g., if there is a failure of the TVRC modems


80


at the FMP


32


or the TVRC modem


114


at the ISD


22


), only analog voice signals might be sent over the subscriber lines


30


. In such a case, the analog voice signals may be directly routed to the line cards


96


, bypassing the TVRC modems


80


, the digital filters


82


, the controller multiplexor


84


, and the TDM MUX


88


. Thus, voice communication is ensured despite a failure of the digital data link. The line cards


96


may convert the analog voice signals into digital format (e.g., TDM format) and send the digitized voice data onto the TDM bus


90


and eventually through the controller


92


and the facilities interface


94


for transmission to one or more external networks.

For high end residential consumers who want more convenience and simplicity in their daily lives and access to the information highway, the videophone is an information and telephony access service that provides a voice and touch screen customer interface to an local exchange carrier (LEC) enabling easy delivery of a wide range of telephony services with cost savings due to automated operator services, customer care, and marketing. New, enhanced services include opportunities such as interactive electronic catalog shopping from the home, advertising, and the ability to offer instant (always on), high speed Internet access to every household, penetrating those markets that currently lack in home personal computers. Additional services include, high fidelity voice and touch screen customer interface for users to a access the network server. This is accomplished via asymmetric high speed data transport. With the higher data transfer rates, 3rd party bill payment, banking, smart card ATM transactions, electronic delivery of consumer product coupons, interactive video teleconferencing, state-of-the-art networking for work-at-home environments, private line services electronic shopping from the home, electronic coupons, advertising, and to high speed Internet access.




Implementation of this new architecture allows for differentiation of local service, will provide new revenue streams from value-added services, and have the potential to significantly reduce operational costs. The architecture is constructed such that additional performance benefits from the existing loop plant are extracted and maximizes use of the existing infrastructure and current systems.




The new architecture implements active services where the user triggers a stimulus by touch, voice or a combination of touch and voice commands to obtain a network based response to expand traditional services as well as provide entirely new services. These responses and the associated services include call connection, information delivery, trigger network response, and performance transactions.




Call connection services provide for calls to be initiated by touching icons corresponding to the called party. It also enables self scheduling of conference calls without the need for an operator as well as initiation of interactive calls with white board augmentation. Class services can likewise be invoked via icons and prompts in a natural manner without requiring memorization of numerical codes.




Information delivery services provide for a simple user interface that enables data base and search engine technology (formerly accessible only to networked computers) to be leveraged for telephony services. For example, access to regional, national or international electronic interaction with yellow and white page directories, navigation and access for voice, e-mail, and fax messages, review of AT&T bill for services, review of AT&T calling plans, review of CLASS and other service offerings. Thus certain marketing, operator services, billing, and customer care functions can be accessed by the customer without the need for an intermediate service representative—reducing operations cost while increasing customer convenience. The video phone eliminates the need for an intermediary to call up information on a screen and read it to the customer and streamlines customer access to information.




In response to a trigger, the network provides a screen interface that enables the customer to obtain operator services without accessing a human operator, obtain credit for wrong numbers automatically, view rate tables, self provision an AT&T Calling Plan or other CLASS services, conduct conference calls, or define a user profile for pointcast on a “ticker tape” that scrolls desired information on the videophone screen. Other trigger services could include a wake up service that automatically calls the user at a preselected time.




Performance transactions allows users via the videophone and its associated card swiper to enable users to perform transactions with security protection. These transactions include paying regular bills with paperless transactions, perform electronic banking including obtaining smart card cash in the home without the need to visit a bank or an ATM machine, conduct E-commerce, purchase products advertised on television via a synchronized ordering screen. The electronic bill payment scheme not only benefits the user but allows the service provider to obtain additional revenue by allowing those companies to out source bill payments to AT&T.




Passive services can also be offered so that active customer responses are not required. These include advertising, providing electronic coupons, personalized news delivery services, and access to community news such as school closings. Providing an advertising feed directly to the customer premises equipment provides a new and potentially very large business opportunity to the local access network provider. Advertising can be displayed on the video phone, whenever the videophone is not in active use. User profiles maintained on the network would enable the advertisements to target customer interests, geographic location, demographics, or some other criteria.




Providing electronic coupons is another passive service opportunity. The electronic coupon can be displayed on the touch screen at appropriate times throughout the day (e.g., orange juice in the early morning) as “screen savers.” By swiping their smart card customers can electronically collect such coupons and use them at the store without the inconvenience of cutting them out of newspapers, etc. At the same time AT&T participates in the coupon industry and has access to another revenue stream.




Delivery of personalized news leverages diverse content assists in the creation of user profiles. In addition, emergency broadcasts relating to flash flood warnings, tornado, and hurricanes, can be broadcast to users in the affected areas without affecting the user's other transactions that are occurring simultaneously. These emergency signals could also be sent with alarms for waking up and alerting users to potential natural disasters.




The offering of interactive services include the combination of a graphics capable touch screen videophone, simultaneous voice and data capability, and a high speed data line to furnish a superior user interface than a traditional voice telephone and so enables a rich collection of new interactive services. These include multimedia enhanced voice calls, virtual PBX services, point and click conferencing, intelligent call management, access to the Internet, and a universal multimedia mailbox.




The multimedia enhances voice calls allows users to supplement voice calls with whiteboard graphics or text. The multimedia format can provide improved customer care, enhanced catalog ordering, and interactive voice and data response applications. In addition, information-on-demand and support for work-at-home access is also provided.




The virtual PBX services include screen pops for message/call alerting, and graphical call management using touch interface with call setup/bridging capabilities. Point-and-click conferencing provides a graphical user interface to initiate POTS calls. The intelligent call management system provides easy instructions to direct call management maintaining a personal registry, mobility manager, call scheduling and “call me back” services, and a personal assistant.




Access to the Internet without a personal computer or modem via Internet Service Provider (e.g., WorldNet) can be provided allowing users without access to a personal computer to have access to e-mail, the World Wide Web, a universal multimedia mailbox with voice, text, audio, and images integrated with a common interface capabilities.




The flexibility of the new architecture allows for implementation of services in phases to minimize impact on the local infrastructure and to allow the service provider to handle and support problems with implementation of services. As installation procedures become routine, additional services can be phased in based on customer demand. Early phases can be target marketed to specific demographics or to regional implementation.




For example, the initial implementation can be tailored to customers who already have two or more twisted pair connects with the local office. The videophone can contain Win32 application programable interfaces (APIs) supporting TCP/IP, POP


3


, RAS, and TAPI protocols with a built in browser. One of the twisted pair will access the AT&T server via a modem (28.8 or possibly 56 kbps). The second twisted pair is used for switched telephony and managed via a graphical user interface. An AT&T server at a WorldNet services center could provide access to white and yellow page directory information, calling plan descriptions, and rate tables. Other interfaces could provide access to the WorldNet Internet services such as the World Wide Web, e-mail, advertising, and E-commerce platforms




A requirement of the touch screen services is availability of a data link to the server. In later phases of implementation, a DSL link to the home is provided with an access protocol that supports simultaneous voice and data services. In the initial phase, the simultaneous voice and data capability is approximated by having the data line automatically call the WorldNet POP when a built-in motion detector is triggered by someone nearby. During these periods of local presence, the AT&T server will put up advertising and personal information on the screen and be available to support touch activated services (e.g., calling, CLASS services), and directory information delivery. All of the line signaling for voice calls to the LEC switch (e.g., DTMF, flash hooks, etc.) for class services and dialing can be generated by the video phone processing engine in response to touch screen commands with support from the second twisted pair for client/server connection as needed.




Later phases of implementation can include the introduction of advanced xDSL access to the customer equipment premises expanding the range of videophone services . These xDSL services will support 7 kHz high fidelity voice and a touch screen customer interface to the network server. This will provide easier delivery of a wider range of telephony services with cost savings due to automated operator services, customer care, billing, provisioning, and marketing. The enhanced services such as 3


rd


party bill payment, banking, smart card ATM transactions, electronic shopping from the home, electronic coupons, and advertising can be implemented with the xDSL connection. In addition, high speed Internet access is possible as well as extending Internet capabilities to users who lack personal computers. Voice calls can be made with a packet-to circuit translator (PCT) for interfacing voice telephony with the local office using the TR-303 signaling simulating modified digital subscriber loop access to the local office.

illustrates a block diagram of the NSP


36


consisting of devices and services used in the implementation of the new architecture. Connected to the SONET trunks


40


and


42


is a gateway


210


. The gateway


210


might also function as the router


185


that was previously discussed. Located around a FDDI ring


202


are the management server


182


, the information database server


183


, and one or more application server clusters


184


, as illustrated in FIG.

.




The connection manager


214


initiates and terminates the placement of telephone calls, while managing the services and messaging. In a typical scenario, the connection manager


214


automates the calling process. This automation involves the executing of computer commands to search records in the database server


218


to ensure that the customer is a subscriber to the desired service or that the called number is a subscriber to the desired service. In addition, the connection manager


214


uses the operations, administration, maintenance, and provisioning


216


to track billing information. After the connection manager


214


obtains the required authorization, it launches the application


212


from the application server


220


.




The OAM&P server


182


contains OAM&P management information


216


consisting of data relating to configuration, capacity, fault, order, traffic activity, design, security, surveillance and testing of the network. The information/database sever


183


contains specific customer information such as user profiles, authorization levels of service, provisioning and electronic commerce. The application server clusters


184


manage and track information regarding computer boot operations and initializations, call management, fault recognition and recovery (FR&R), application binding, maintenance and design, application invoicing, craft interface enhancement, application downloads, translations (Xltn), recent change and verify (RC/V), authorizations and registrations, configurations and performance statistics (Pertf Stat).

184


and the operation, administration and maintenance (OAM) server


182


. In both the application server


184


and the OAM server


182


, the software layer architecture is the same. In data link layer, the operating system kernel


250


contains a C application programable interface


252


for interfacing with communication, input/output and interprocess communication protocol IPC. The data link, network, and transport layer contain middleware including the C applications


252


, C++ wrappers


254


and the adaptive services layer


256


. The C++ wrappers optimize the C library functions and the middleware puts intelligence into form object oriented programs in the transport layer to help applications route upwards and downwards in the protocol hierarchy. The session and transport layers contain service applications


260


and framework applications


258


, respectively. The application layer contains the service/applications


262


.





FIG. 8

illustrates protocol hierarchy for the application server platform software architecture. The physical layer includes the operating system kernels


270


for fault tolerance, process/thread subsystems, communication subsystems, and virtual memory subsystems. The data link layer contains the following C application programable interface sets

294


, user interfaces


296


, and the OAM&P services


298


. These protocols use a fault tolerant Unix language to make the transition between interfaces transparent.

illustrates the protocol hierarchy for the OAM&P server platform software architecture. The physical layer includes the operating system kernels


300


for fault tolerance, process/thread subsystems, communication subsystems, and virtual memory subsystems. The data link layer contains the following C or other application programable interface sets


302


: thread, stream, socket, name pipe, socket poll, dynamic link, memory map, and IPC. The network layer contains the operating system adaption layer


304


, the thread manager, synch wrapper, spipe SAP, socket SAP, FIFO SAP, MEM MAP, and IPC wrapper. The transport layer contains the adaptive service executive

. The distributed services access protocol


329


is supported by the session layer distributed object services


330


, the transport layer process services


332


and the network layer message manipulation and transport


334


. These protocols also use a fault tolerant Unix language to make the transition between interfaces transparent.




In addition to the devices disclosed in

FIG. 1

,

FIG. 10

illustrates overall service concepts. Key aspects of the technologies employed in this architecture is the use of self-adaptive DSLs


30


. The self-adaptive DSL supports sophisticated digital signal processing including high fidelity packet voice transmission and robust automatic route selection (ARS). ARS directs outgoing, business group line calls to the customer's most preferred available route allowing the customer to preselect a sequence of up to four private routes for each code point in the PSTN


46


for which a charge applies.




Included in

FIG. 10

is the automated services agent


338


and an IP circuit converter


340


. The automated services agent


338


supports the interexchange carrier's OSS, messaging systems, electronic commerce, and advertising systems. The IP circuit converter


340


converts IP packets into traffic suitable for transmission via circuit-switched network elements.




The services offered to consumers with this architecture include high speed Internet access, 7 kHz telephone voice quality service, graphical user interfaces for ease in accessing automated services, provisioning and billing. Capabilities for 7 kHz bandwidth voice calls allows for 64 kbps transmission rates with a bit error rate less than 10


−6


and a delay of less than 150 millisecond. For telecommuters, in addition to the consumer services, the architecture supports high speed corporate local area network (LAN) Intranet access. For business customers, the architecture supports secure electronic commerce and personalized delivery of advertising to consumers with the capacity to tailor the advertising campaign to the consumer's profile.




The architecture supports the following connectivity services: high speed Internet access, CD quality voice transmission, asymmetrical and symmetrical high speed data transmission rates, two-way 384 kbps video transmission, video conferencing, wireless voice mobility within the home and possibly within the neighborhood, conversion of cellular traffic to traditional land line service within range of the ISD, wireless data mobility within close proximity to the ISD. The architecture support the following information call management services: custom local area signaling services (CLASS), call alerting and redirection, electronic commerce via access to the Internet and the use of smart cards or credit cards, multiple voice connections, telephony management, secure personalized Intranet (voice and data), access to community online information services, personalized and multiple personalized Intranet, access to interactive multimedia, and movies on demand.




Online management is also possible implementing user activated service provisioning, electronic initiated service inquiries, electronic billing and bill payment schemes, voice activated command execution, “follow-me” service profiles, and virtual home location profiles. User interface capability includes unique digital signatures, touch screen and dialing pad access to services, integrated personal computer access, smart card reading and recharging capabilities, voice dialing, compatibility with cellular phones (for example, IS54, IS95, GSM or other cellular phones), compatibility with personal digital assistants, network computers and personal computers via RF modems.





FIG. 11

illustrates the protocol hierarchy between the ISD and the FMP. For voice calling services, the TVRC protocol


400


provides the physical layer. The data link layer


402


attaches a 6 bit header to the data packet and the network layer


404


is supported by Q.931, pulse code modulation (PCM), or G.722. The standard Q.931 supports out-of-band signaling. For data transmission, the TVRC protocol provides the host-to-network layer


401


. The Internet layer


403


is supported by IEEE 802.3 standard. The Internet layer


405


also supports the Internet Protocol (IP). The Internet layer


403


and


405


define an official packet format and deliver IP packet to their intended destination. The transport layer


407


is supported by the transmission control protocol (TCP), user datagram protocol (UDP) and resource reservation protocol (RSVP).





FIG. 12

illustrates the protocol hierarchy between the FMP and the network. The SONET protocol


408


is used in the physical layer for both short term (option 1) and (long term option 2). In the short term, the data link layer is supported by TR303 [


410


]. Eventually, the ATM


412


protocol will replace TR 303 [


410


] in the data link layer. In the short term, the network layer is supported by Q.931 [


414


] for the transmission of signaling information and G.711 (PCM) or G.722 [


416


] will support the transmission of voice signals. In the long term, Q.2931 [


418


] will support signaling information and G.711 (PCM) or G.722 [


420


] will support the transmission of voice signals. In the long term, SAAL


422


and ATM adaption layer 1 (AAL


1


)


424


supports the signaling and voice traffic, respectively. The AAL is fully independent of the physical layer, and converts higher-layer information, such as data packets, into ATM cells for transmission across the ATM network. At the receiving end, the AAL converts the cells back into the higher-layer information.





FIG. 13

illustrates one possible data protocol hierarchy between the FMP and the network. At the host-to-network layer, TVRC, SONET protocols


426


or ATM protocols


428


will be used for the transmission of data from the FMP


32


to the network. In the Internet layer, out-of-band signaling is performed by SAAL


430


and traffic is supported by AAL


5


[


432


]. Also in the Internet layer, point-to-point


434


and point-to-point tunneling protocol


436


is used to transport traffic as well as IP


438


. In the transport layer, traffic is supported by TCP


440


.





FIG. 14

illustrates the protocol hierarchy for voice services (option 1 ) employing end-to-end ATM. from the ISD


22


to the PSTN


46


. The ISD


22


is connected to the FMP


32


by a self adaptive DSL


30


in the physical layer. The ISD


22


,the FMP


32


, ATM switch


449


and the local service office (LSO)


451


have their data link layer supported by ATM


444


. The ISD


22


and the LSO


451


have their network layer by AAL


1


[


446


] and their transport layer supported by PCM


448


. At the FMP


32


, the data link layer is supported by ATM


444


. Links from the ATM switch


449


to the FMP


32


, the NSP


36


and the LSO


451


, have the signaling aspects of these connections supported in the physical layer by Q.2931.





FIG. 15

illustrates the protocol hierarchy for voice services (option 2) employing the TR-303 interface. The data link layer


454


in both the FMP


32


and the LSO


449


is supported by TR 303 across the local access network.





FIG. 16

illustrates the protocol hierarchy for data services employing point-to-point over ATM from the ISD


22


to the Internet backbone


50


. The ISD


22


is connected to the FMP


32


by a self adaptive DSL


30


in the host-to-network layer. The Internet layer at the ISD


22


is supported by IEEE 802.3 [


466


] and the transport layer is supported by IP


468


. At the FMP


32


, IEEE 802.3 [


466


] between the physical layer and the Internet layer for connections between the FMP


32


and the ISD


22


. For connections between the FMP


32


and the ATM switch


449


, Q.2931 signaling is used. Between the FMP


32


and the ISP access node


460


, a permanent virtual circuit (PVC)


470


can be established to save bandwidth associated with circuit establishment and tear down in those situations where certain virtual circuits must exist all the time. When these conditions do not exist, a switched virtual circuit (SVC)


472


can be established to dynamically establish a circuit on demand.





FIG. 17

illustrates the protocol hierarchy for data services using ATM signaling.

FIG. 17

is similar to

FIG. 16

in that both PVCs


470


and SVCs


472


can be established based on system requirements.





FIG. 18

illustrates the virtual private data network “Extranet” between the FMP


32


and an access node


490


using point-to-point tunneling protocol. Point-to-point tunneling protocol wraps point-to-point packets in an IP format and uses a layer three protocol. The flexibility of point-to-point tunneling protocol allows the implementation to be client initiated or client transparent, but does require IP support. From the access node


490


, users can connect to corporate private data networks


492


to create a secure connection between the customer services equipment and a private network.





FIG. 19

illustrates the protocol hierarchy for establishing a point-to-point tunneling protocol from the customer services equipment to the private data network. The ISD
