`
`Getting
`The Message
`WithUMS
`
`introducing Unified Messag-
`AT&Tis
`ing Service (UMS), a messaging archi-
`tecture designed to integrate all of
`AT&T's message products and systems
`into one convenient
`service. UMS al-
`lows people to easily send messages and
`documents
`by making addressing
`transparent across the recipient's dif-
`ferent messaging systems.
`It permits
`trieval of a variety of message types
`from a single, user-chosen "mailbox"
`that's accessible from virtually any-
`where. This article describes the UMS
`concept,
`the UMS architecture, and the
`convenience of messaging in a UMS-
`equipped office.
`
`re-
`
`In today's typical modern office
`there may be an electronic mail ser-
`vice as well as Message Center Service
`whose attendants answer the phones
`and "write" electronic message slips.
`Employees also may have personal
`computers (PCs) with a local messag-
`ing capability. To get messages, a per-
`son must access the electronic mail
`service with a PC or terminal, call the
`Message Center Service agent or walk
`to a printer, or go to a secretarial mes-
`sage board for phone messages.
`Getting messages to or retrieving
`messages from all these places is diffi-
`cult enough when you're in the office.
`It can be almost impossible when
`you're away. Even worse, calls can be
`misdirected or go unanswered be-
`cause of poor staff coverage. Studies
`have shown that roughly 50 percent of
`all messages fail to reach their destina-
`tions on the first try. And because
`people use messaging improperly,
`
`some 75 percent of all messages are
`one-way communications that don't
`require a response.
`Office workers also need to ex-
`change information that is more elab-
`orate than simple text messages. Mul-
`tiple copies of draft documents, for
`instance, are typically distributed
`among various departments for re-
`view. This process can be streamlined
`when the document can be distribut-
`ed, revised, and returned electronical-
`ly. Spreadsheets, graphics, picture im-
`ages, and encoded voice messages also
`must be transmitted throughout of-
`fices. But when workers try to ex-
`change these documents across dis-
`similar messaging products or
`systems made by different manufac-
`turers, they often are not usable be-
`cause their document formatting
`methods are inconsistent or don't
`contain enough information.
`
`AT&rS SOLUTION: UMS
`AT&T's solution to these dilem-
`mas is Unified Messaging Service
`(UMS), a collection of AT&T messag-
`ing products and systems and a corpo-
`rate messaging architecture.
`The system shown in Figure 1is
`now operating at several AT&T loca-
`tions. Typically, the headquarters has
`an AT&T System 85 PBX with an ap-
`plications processor supporting
`AT&T's Message Center Service for
`external call coverage. Users also have
`AT&T's AUDIX voice-mail system
`for internal call coverage. The head-
`quarters location uses AT&T's OTS,
`an integrated voice and data system,

`
`UMS OBJECTIVES
`The objectives ofUMS are to:
`o Integrate all of AT&T's cur-
`rent messaging products and establish
`integration principles for future
`productso Further AT&T's commitment
`to open-systems architecture by sup-
`porting international messaging stan-
`dards and providing interfaces to se-
`lected vendor messaging systems
`o Establish a consistent method
`of presenting information to the user
`and o Incorporate new messaging
`technologies in a consistent manner.
`VMS meets these objectives by
`providing a single "alert" for all mes-
`sages, a single voice or text "mailbox"
`for each user, a common interface for
`message preparation and retrieval,
`and a standard format for exchanging
`information with other messaging
`products.
`A typical modern officewon't be
`
`for officecommunications. The
`branch offices use AT&T mail-a
`network-based electronic mail ser-
`vice. These offices also are served by
`the System 85 PBX. All Message Cen-
`ter Service users have their telephone
`messages forwarded to OTS or AT&T
`Mail. In addition, both OTS and
`AT&T Mail control the message-
`waiting lamps on phones.
`For people served by this system,
`the UMS mailbox-the
`single access
`point for all messages-is
`in OTS or
`AT&T Mail. Since OTS and AT&T
`Mail both use the same UMS underly-
`ing architecture,
`these two groups of
`users can exchange mail and docu-
`ments to keep the branches up to date
`on headquarters activities, and vice
`versa. Finally, AUDIX sends notifi-
`cations to OTS and AT&T Mail.
`From the perspectives of users, the
`UMS mailbox provides universal ac-
`cess to all their messages from all their
`messaging systems. When people are
`out of the office,they can use AT&T
`Mailtalk or Speak-To-Me" Messag-

`"typical" when equipped with
`AT&T's UMS products and services.
`For example, an employee may
`choose to use either a voice or a text
`service as the mailbox to retrieve and
`respond to all messages. If a PC is
`chosen, it could be used manually or
`be set up to automatically retrieve
`electronic mail from public, corporate
`and departmental mailservices, and
`to retrieve "pink slip" telephone mes-
`sages from the message coverage ser-
`vice. When people are out of the of-
`fice, they can call in from any
`Touch-Tone phone and hear all their
`pink-slip and PC messages by means
`of a text-to-speech converter. (See
`panel on page 31.) In addition, people
`can receive, edit and return docu-
`ments, spreadsheets and graphs from
`dissimilar systems without losing in-
`formation, such as formatting codes.
`
`UMS INTEGRATION PRINCIPLES
`Individual AT&T messaging ser-
`vices and products within the UMS
`
`family each share a set of five integra-
`tion principles. They are: unified
`message mailbox, unified message
`retrieval, unified message prepara-
`tion, universal connectivity, and uni-
`versal alerting and notification.
`
`Unified Message Mailbox
`The UMS mailbox is the one ac-
`cess point for all messages regardless
`of their type or the sender's system.
`(See Figure 2.) This capability stems
`from the underlying application ar-
`chitecture which forwards messages
`and message notifications from one
`service to another.
`
`Unified Message Retrieval
`People can retrieve messages
`from their chosen UMS mailboxes us-
`ing any of several terminal types from
`any location. This gives them access
`to any of their messaging services
`(Message Center Service coverage,
`electronic mail, and voice mail); from
`the office,home, and while traveling;
`
`and from a telephone, data terminal,
`PC, or public phone.
`Due to today's technology limi-
`tations (e.g., converting voice to text),
`some retrieval devices may be able to
`retrieve only parts of a message (or
`messages) in certain forms across re-
`trieval devices. For example, from a
`data terminal a person will be able to
`retrieve only the voice-mail header
`(scanline) identifying the sender, date,
`and time. Using this information,
`the
`person will be able to select the de-
`sired message and hear it spoken in its
`entirety on a phone. A limited-display
`digital phone, such as the AT&T
`Model 7405D (see Photo 2), can re-
`trieve only a scanline and a short. mes-
`sage. Conversely with today's text-to-
`speech conversion technology, users
`can retrieve text messages in voice
`form.
`A consistent set of message re-
`trieval commands is available for ev-
`ery device. Photo 1shows the layout
`of the Universal Message Retrieval

`
`Commands available on a Touch-
`Tone phone. This phone is used for
`AT&T voice store-and-forward ser-
`vices (AVDIX) and for text-to-speech
`retrieval of text messages-AT&T
`Mailtalk and Message Center Service
`Speak-To-Me services. (Seebelow.)
`These same message retrieval com-
`mands will be available on limited-
`character display phones' used with
`AT&T PBXs (see Photo 2) and on full-
`screen terminals and PCs (seePhoto 3).
`
`Unified Message Preparation
`Through this principle, VMS en-
`ables users to create and send a mes-
`sage with the system providing ad-
`dress resolution; consequently,
`they
`don't have to know the recipient's
`messaging system or retrieval device.
`A person with AT&T Mail, for exam-
`ple, can write a meeting notice and
`send it to several people who mayor
`may not be AT&T Mail users. One re-
`cipient may get the meeting notice
`from the u.s. Postal system via
`AT&T Mail's paper gateway feature.
`Another recipient may have only
`AT&T's Message Center Service, so
`that he or she may hear the meeting
`notice through text-to-speech conver-
`sion or by calling the Message Center
`Service attendant. Yet another recipi-
`ent may receive the meeting notice on
`a VNIX® Pc. In each case, the sender
`simply creates the meeting notice, en-
`ters the names and addresses of the re-
`cipients, and sends the message.
`
`Universal Connectivity
`This fourth principle provides
`the ability to move messages, docu-
`ments, and other information through
`the system (or network) among mes-
`saging products and users. Since both
`the sending and receiving systems are
`based on the same application archi-
`tecture and share a common messag-
`ing protocol (see panel on page 32),
`they can interpret
`the messages and
`process their contents. In some in-
`stances, message conversions (text-to-
`
`speech) and object conversions (be-
`tween document coding standards
`such as Wang' and IBM2's DISOSS)
`are performed.
`
`Universal Alerting and Notification
`When VMS users receive text or
`voice messages, they're alerted by the
`phone's message-waiting lamp or by a
`short statement or icon on the termi-
`nal screen. They then go to their mail-
`boxes to retrieve their messages.
`When messages can't be forwarded,
`these users are notified of new mes-
`sages on other services -"You Have
`AVDIX Messages." (See below.)
`
`SYSTEM VIEW
`AT&T messaging products fit
`into three broad messaging categories:
`electronic mail, message coverage,
`and voice mail. Messaging applica-
`tions on systems in each category are
`
`integrated through adherence to the
`VMS principles; the systems can ex-
`change information because they
`share a common underlying VMS
`architecture.
`
`Electronic Mail
`Office Telesystem (OTS). OTS is
`an integrated voice and data office
`communications and executive man-
`agement system for managers and
`their secretaries. OTS is a shared sys-
`tem that includes data terminals,
`desktop workstations (PC 6300, PT
`505, PT 510) and peripherals connect-
`ed to AT&T's 3B computers. OTS
`can be configured for as few as four or
`as many as 100 users and currently
`supports a variety of office applica-
`tions including:

`AT&T Mail. AT&T Mail is a
`network-based electronic mail service
`that enables subscribers to send mail
`to anyone in the United States, wheth-
`er they subscribe to the service or not.
`The service can be accessed via a PC
`(PC 6300 or compatibles, MacIn-
`tosh', or UNIX PC), a data terminal,
`a word processor, or a Touch-Tone
`phone. For added flexibility, AT&T
`Mail provides gateways to telex and
`postal services. The telex gateway al-
`lows mail to be sent to and received
`from a telex endpoint and the "paper"
`gateway provides a link to a courier
`service or the U.S. Postal Service. In
`addition, AT&T Mailtalk service con-
`verts text to speech for retrieving mes-
`sages from a Touch-Tone phone.
`Private Message Exchange
`(PMX). PMX is a premises-based ver-
`sion of AT&T Mail's Network Ser-
`vice and is intended for in-house ap-
`plications. It provides AT&T Mail's
`Network Service features for single-
`location businesses, enabling them to
`manage their intra-building traffic.
`This is similar to a PBX. To expand
`communications to people who are
`n?t electronic mail subscribers, PMX
`gives access to the paper and telex
`gateway features of AT&T Mail Net-
`work Service. PMX also provides a
`consistent user interface for data ter-
`minals, PCs, and LANs (STARLAN
`and 3BNet) that access PMX or
`AT&T Mail Network Service.

`The initi~l AT&T messagiIlg protocol, Message Transfer Architec-
`ture (MTA),
`IS ,the fir~t phase of AT&T's support for MHS, and it sup-
`ports the MHS s m::chltectural layered model and its message service ele-
`ments. MTA contains two subarchitectures: message service architecture
`r (MSA) and content
`t
`.description architecture (CDA).
`Th~ M~A provides the structure ~nd fun~tions required for
`f exe~anglllg iaformation: amongsmessagingeservieessdt, contains the .
`Universal Message Transport Header,
`the Universal Message Report
`Header, and the m.essage services protocols. The Universal Message
`Transport Header IS the message envelope. It contains information about
`the messag~ transmission such as, the origination and destination ad-
`d~esses, a ..tlm.e-stamp, and various transport options such as grade-of-ser-
`'Vlce~~he tJlllv~rsal Message Report Header retu:rns'transIi1issi6i1~retated
`status mforma~iOn. The message services protocols contain functions re-
`quired .by specific B?-essa~ingap~lications. such as electronic mail (copy"
`to, subject) and notification services, such as message-waiting indicator
`and message forwarding.
`.
`The CD~ describes the contents of themessage, This may be as
`SImple as a bne~ user-entered text. message or as complex as a voice mes-
`sage embedded m a word-processing document containing a graph and
`spreadsheet.
`.Tlie CD.A consists of the Universal Content Description
`He~der, content services protocols, and the described contents. The
`Universal ~ontent Desc~p~i<;lnHeader contains fields describing the
`type; encoding characteristics, and length of the. contents. The content
`services protocol describes the attributes and structures of non-standard
`content structures such as simple contents-e-graphs and spreadsheets-as
`well as complex contents-voIce-annotated
`text.
`'
`The modular structure of MTA allows it to be extended easily.
`MSA andCDA can be enhanced by adding new services with included
`protocols, by appending a new. proto~ol to anexistirig service, or by add-
`mg a new ?ont~nt
`type to the universal content description header.
`A major difference between the MHS and MTA protocols is that
`t~eMTA has a completely readable syntax in ASCII,while
`the MHS is
`bm~ry encoded. T~e readable feature of MTA allows messages to be
`dehve;ed to anddlspl~ye~ on systems evert when Jhe receiving' system
`doesn t kll~w theapphca.tl0~ protocol.

`layers
`are compatible; communication between MTA andMHS

`quires ~.s~raightfo;('.yardconyersion at the presentation layer. AT&T will

`
`Message Coverage
`Message Center Service. This is
`an attendant-staffed, call-coverage
`service whose software runs on an
`AT&T applications processor that's
`connected to an AT&T System 75
`PBX, System 85 PBX, or a Dimen-
`sion" PBX. The service sends unan-
`swered calls to the Center's atten-
`dants who take and relay the
`messages. The service permits users to
`give the attendant a general message
`for all callers or a specific message for
`a particular caller.
`When an attendant
`
`takes a mes--

`
`

`
`sage, the message-waiting lamp on the
`called person's phone comes on. The
`called person can retrieve messages ei-
`ther by calling the attendant, by read-
`ing messages on a digital telephone's
`display, by using a printer, by using a
`data terminal to log into the Message
`Center Service, or by calling Speak-
`To-Me messaging service. The latter
`synthesizes speech from text, deliver-
`ing it via a Touch-Tone phone. Ifpeo-
`ple using Message Center Service also
`have electronic mail, they can have
`messages forwarded to their electron-
`ic mailboxes. This capability stems
`from the Unified Messaging Manager
`(UM Manager), software running on
`an AT&T applications processor
`that's linked to an AT&T PBX.
`Leave Word Calling. This ser-
`vice allows people served by an
`AT&T System 75 PBX, System 85
`PBX or a Dimension PBX to leave
`short, "please call" messages for oth-
`ers on the same phone system or net-
`work without having to go through
`Message Center Service or a secre-
`
`tary. When a person being called
`doesn't answer, the caller hears a spe-
`cial tone. By pressing a button on the
`telephone or dialing an access code,
`the caller can leave a short message
`like: "Call John, extension 2336."
`When the called person returns to the
`office, the message waiting lamp on
`the phone will be lit, indicating there's
`a new message. Leave Word Calling
`messages for Message Center Service
`users can be stored in the Message
`Center Service database and retrieved
`like any Message Center Service mes-
`sage. Users also can forward the
`Leave Word Calling messages to their
`electronic mailboxes.
`UM Manager. UM manager
`software permits message exchanges
`among call-coverage services such as
`Message Center Service and Leave
`Word Calling, and electronic-mail
`services such as OTS or AT&T Mail.
`The UM Manager also enables elec-
`tronic mail services to light user's
`message-waiting lamps when there
`are new messages.

`AUDIX. AUDIX gives people
`call coverage for calls that would oth-
`erwise go unanswered, and the capa-
`bility to send and receive voice-mail
`messages from any Touch-Tone
`phone. AUDIX also lets a user create
`a personal greeting for responding to
`unanswered calls. Because of the un-
`derlying UMS architecture and a
`common AT&T voice encoding
`scheme, these users will be able to ex-
`change stored voice messages among
`separate processors. A future network
`of AT&T's voice products (AUDIX,
`and the UNIX PC and 3B voice store-
`and-forward circuit boards) could ex-
`change stored voice messages. This
`would allow UNIX PC users to have
`their AUDIX messages forwarded to
`the PC for retrieval via its built-in
`phone.
`
`ARCHITECTURAL MODEL
`UMS's underlying architec-
`ture-implemented
`in all of the above
`AT&T products, systems, and ser-
`vices-is based on international stan-
`dards for systems communication,
`the
`Open Systems Interconnection (OSI).
`AT&T has taken the OSI structure as
`the foundation for AT&T Systems
`Architecture.
`(See Figure 3.) Further-
`more, AT&T has taken the interna-
`tional standard for messaging-the
`Message Handling System (MHS)
`X.400 series-included
`several addi-
`tional capabilities and used it as the
`basis for UMS architecture.
`(See pan-
`el on page 32.)
`OSI is evolving as a family of in-
`ternational standards for information
`movement and management. OSI
`consists of a seven-layer reference
`model that has service and protocol
`standards developed-or
`in the pro-
`cess of being developed-for
`each lay-
`er. OSI is being supported inter-
`nationally by standards bodies,
`governments,
`telecommunications
`companies, computer vendors, manu-
`facturers, and end-users.
`
`Google Ex. 1103, pg. 10
`
`

`
`The AT&T Systems Architec-
`ture specifies the objectives, concepts,
`structure and plan for AT&T infor-
`mation movement and management.
`This architecture is an expansion of
`the OSI reference model and has three
`subarchitectures:
`o Application architecture de-
`scribes the interfaces to both the users
`and services and the protocols re-
`quired to support the services; UMS is
`one of the first application
`architectures.
`o Transport architecture de-
`scribes the protocols for an overall
`transport service that accesses the va-
`riety of AT&T network capabilities.
`o Network architecture de-
`scribes the protocols for the various
`network services and their media.
`
`UMS IN THE OFFICE
`In an officewithout UMS, a per-
`son goes to a secretary for telephone
`messages, to an inbox for paper mes-
`sages and documents,
`logs into an
`electronic-mail service for electronic
`mail and documents and, if necessary,
`also calls into the voice-mail service
`for voice mail. WithUMS, a single re-
`trieval action can give access to all
`these messages through the UMS
`"mailbox." Let's look at three typical
`officemessaging situations, with dif-
`ferent services providing the "mail-
`box," to see how the UMS architec-
`ture integrates them.
`
`Voice-mail Mailbox
`This officehas Message Center
`Service coverage for external tele-
`phone calls and an AUDIX voice-
`mail system for internal call coverage.
`In addition, the office has AT&T Mail
`Network service. The user has select-
`ed AUDIX as the UMS mailbox;
`therefore, to retrieve messages, users
`call into AUDIX, hear their messages
`and are told that they have new text
`messages. Then they access AT&T
`Mail, and through the Mailtalk text-
`to-speech converter, hear all their text
`
`messages including telephone mes-
`sages receivedat
`the message center.
`AT&T Mail sends message alerts to
`the user's PBX so that message-wait-
`ing lamps go on when new mail ar-
`rives-voice
`or text-and
`go off when
`the mail is retrieved.
`
`Text-Mail Mailbox
`This officehas secretarial cover-
`age for external phone calls, AUDIX
`for internal calls, and OTS for elec-
`tronic mail. For people who are in the
`officemost of the time, OTS has been
`designated as the UMS mailbox. The
`secretary enters all telephone mes-
`sages into OTS. AUDIX forwards no-
`tifications of new voice mail messages.
`Since OTS can communicate with the
`PBX system, message-waiting lamps
`come on whenever new mail arrives.
`Then users check OTS and see a list of
`scanlines for each new message. These
`now include telephone messages,
`voice-mail notification, and electron-
`ic-mail messages. Users can read all
`the messages from this access point.
`To retrieve AUDIX messages, users
`push a special AUDIX retrieval but-
`ton on the OTS terminal and OTS
`automatically connects to AUDIX.
`From the user's perspective, logging
`into OTS provided access to all mes-
`sages, both voice and text, in one re-
`trieval action.
`
`Integrated Voice/Text Service
`Mailbox
`In this example, an officeis
`served by the same messaging services
`as before: a secretary for telephone
`coverage, AUDIX for internal call
`coverage, and OTS or AT&T Mail.
`However, this officeprovides some
`users with a more sophisticated re-
`trieval device, a voice/data integrated
`terminal or PC (with an internal voice
`board for voice storage). The differ-
`ence between these users and the pre-
`vious ones is that while both have uni-
`versal access to their messages
`through their UMS mailbox, these us-
`
`ers will also be able to receive actual
`voice mail.notjust

`having AUDIX forward voice-mail
`messages to them. When this new fea-
`ture becomes generally available,
`these users will be able to have their
`voice mail messages forwarded to the
`same place as electronic messages.
`This will eliminate the need to call
`AUDIX to retrieve voice-mail mes-
`sages. When users want to hear a mes-
`sage, they simply pick up the phone
`and listen.
`
`SUMMARY
`UMS provides a common archi-
`tectural base for unifying office mes-
`saging systems. UMS integrates a
`broad range of AT&T's voice and
`data products with selected vendor's
`messaging products and with MHS,
`the international messaging system.
`This integration stems from the abili-
`ty to exchange complex information
`between these systems, through a con-
`sistent user interface across AT&T
`products, and through universal ac-
`cessibility from the home, the office,
`or on the road .•
