------------------------------------------------------------------------------- BT TYMNET RESTRUCTURES Washington, D.C., February 6, 1990 -- BT Tymnet, suppliers of the international value-added network, TYMNET (r), announced today a company-wide restructuring program at Communications Networks '90. This progam is a direct result of the integration of the British Telecom subsidiary, BT Dialcom, Rockville, MD, and the operating divisions acquired from McDonnell Douglas - Network Systems Company, Network Application Systems, Applied Communication Systems (ACS), and Payment Systems Company. The new entity, BT Tymnet Inc., will be closely focused on providing high-quality, high-value, business solutions to the world-wide market for telecommunications applications systems, products and services. INTEGRATION OF SALES AND MARKETING All of the systems, products and services marketed under the various companies will now be available from the new company, BT Tymnet Inc. This includes the products and services associated with the TYMNET Network, as well as the electronic messaging programs DIALCOM and OnTyme, the electronic data interchange program, EDI*Net, and the point-of-sale services, Electronic Draft Capture, and Credit Authorization. Sales operations have also been aligned to reflect the business solution focus of the new product portfolio. BT Tymnet Corporate Headquarters are located in San Jose, California, USA, with regional offices located in the United States, Canada, Europe, and the Pacific Rim. KEY ELEMENTS TO SUCCESS "Winners in the world-wide race to supply global networking solutions will share one fundamental quality - a committment to serving the business of their customers. Suppliers of high-quality, reliable, and timely solutions to the business of daily communications, based on superior technology, will take the lead. This restructuring represents our continuing commitment to our customers that THEIR business comes first," stated Art Parsons, Senior Vice-President Sales and Marketing, BT Tymnet. BT TYMNET INC. BT Tymnet Inc., an international value-added network supplier, is one of the world's largest providers of shared, dedicated and hybrid network solutions. The company owns and operates the TYMNET Network, which offers protocol conversion, error-protection, enhanced security features, electronic data interchange (EDI), card services and electronic messaging. The TYMNET Network is accesssible from most countries throughout the world. _________________________________ BT TYMNET TO PROVIDE ACCESS FOR DIGITAL'S INDEPENDENT SOFTWARE VENDORS SAN JOSE, California, February 6, 1990 -- BT Tymnet Inc. and Digital Equipment Corporation announced today that the international value-added network TYMNET(r) has been chosen as the access provider for the Digital Independent Software Vendor (ISV) Program, ISVNet. Digital, a long time customer of BT Tymnet, established the ISVNet to identify and work with third-party software developers -- worldwide -- interested in writing applications for all of Digital's strategic platforms. ISVNet is used to link Digital's ISVs and CSOs (Complimentary Solutions Organizations) with Digital personnel, and is becoming a primary way these third parties communicate with Digital. BENEFITS OF THE ISV PROGRAM By utilizing the TYMNET Network, ISVs and CSOs gain easy, low-cost access and dependability via a local call in over 850 cities nationwide, as well as over 80 countries worldwide. "We estimate the cost for an hour of connect time will decrease to an average of $5 versus $30 an hour previous to this agreement," said Mike Mancuso, group marketing manager for Digital's Corporate Independent Software Vendors Group. "Our experience with ISVs leads us to believe that a cost-effective, secure data network is a more efficient means of communicating with CSOs and ISVs than a traditional telephone support program," said Mancuso. The ISVNet is currently used by software developers as an electronic-mail system to Digital engineers and for access to on-line Notes Conferences, which focus on common development issues. Digital also uses the ISVNet to announce training classes, which it provides free to its ISVs and CSOs, and as an electronic bulletin board. Digital's CSO and ISV programs are open to all companies, regardless of size or number of employees. In a research report compiled by the AberdeenGroup, they concluded that "Digital's ISV Program is far and away the most comprehensive hardware manufacturer-sponsored technical-support program available for ISMs (Independent Software Manufacturers) today." Aberdeen recommends that ISMs who want their applications to run on larger-than-PC, state-of-the-industry systems join the other ISMs who are already in Digitals's ISV Program. BT TYMNET INC.

Known as CONCERT (TM), British Telecom's open network management capability will be built on internationally-agreed open standards, allowing it to interface with systems from other suppliers. It will allow customers end-to-end management capability of their public, private, and hybrid networks, and will automate many routine tasks while optimizing network performance. David Dey, Managing Director of British Telecom's Communication Systems Division, revealed the company's strategy for this new fast-emerging area of communications which he said was "fundamental to achieving our goal of becoming the world's most successful telecommunications company." Mr. Dey continued: "Companies' networks have become the very lifeblood of their businesses. Investment in such networks runs into millions of dollars. With increasing deregulation, these networks are often patchworks of equipment from many different suppliers." "Integrated management and control is fast becoming the most important communications activity in major customer networks around the globe. We are totally committed to providing advanced solutions for our customers as a major part of our strategy to become the world's leading telecommunications network supplier. This strategy is based on close, cooperative alliances with other suppliers, using open standards to achieve full end-to-end systems management." Mr. Dey said that, "in consequence, British Telecom had established a Network Management Liaison Group with many other suppliers. This supplemented its collaboration with other vendors through its membership in the OSI/Network Management Forum." He added: "CONCERT is designed to cross the boundaries of public, private and hybrid networking in both voice and data. Because networks are part of an overall information system, close cooperation with computer system suppliers is essential." "In particular, British Telecom is working with IBM and other major computer companies to look at ways of establishing direct interworking between our respective network management systems, through open interfaces." CONCERT significantly builds on British Telecom's global activities including those of its new subsidiary BT Tymnet, the worldwide value-added data services and private networking supplier based in California, and its relationship with Northern Telecom for distributing the MERIDIAN range of PBXs. Both BT Tymnet and Northern Telecom's products are intended to interface to CONCERT. Mark Baker, President of BT Tymnet, said: "BT Tymnet's own UNIX-based network management capability will be upgraded to provide interfaces to the CONCERT integration system. It will be repositioned to form a strong component of the CONCERT initiative." British Telecom's ability to exploit CONCERT for its major customers has grown out of its expertise in this area. During the last few years, the company has built up a team of systems architects, designers and software engineers - now over 1,000 strong - to support development of its network management products and services. It is deploying the latest technology, including expert systems, and has recently concluded one of the worldUs largest contracts in this area with Telefonica of Spain. As another indication of its commitment in this area, British Telecom was a key founder of the OSI Network Management Forum. Established in 1988, it now comprises nearly 100 leading communications and computer companies from 13 countries. The Forum is working rapidly to agree on specifications to make multi-vendor network management a reality. Keith Willetts, one of the British Telecom executives responsible for the CONCERT program, is currently President of the Forum. Mr. Willetts said: "As President of the Forum and closely involved in British Telecom's plans, I have been able to ensure that CONCERT is harmonized with the Forum's activities." CONCERT is being implemented in the key networking products and services which make up British Telecom's Customer Managed Communications portfolio. It will be focused initially on value-added data networking, both in the UK and worldwide. Local area networks, data communications and packet-switching products are included. British Telecom is conducting internal trials to add management capabilities to its private circuit services portfolio in the UK. CONCERT technology and interfaces will be used to give major customers on-line access to British Telecom's business Service Centers for service requests and service resolution. It will also be applied to voice networking involving the company's relationship with Northern Telecom. Trials of products implementing CONCERT begin as early as fourth quarter 1990, with customer availability in progressive releases during 1991. ### CONCERT is a registered trademark of British Telecom. ------------------------------------------------------------------------------- BT TYMNET AWARDED MOTOROLA CONTRACT TO PROVIDE NETWORK FOR CoveragePLUS SYTEM Will Link Nationwide Vehicle Communication and Location System SAN JOSE, California, May 9, 1990 -- BT Tymnet Inc., provider of the international value-added network TYMNET(R), announced today that they have been chosen by Motorola, Inc., Communications Sector to support the CoveragePLUS(TM) system. The three year contract is worth over $15 million. CoveragePLUS is the first long-haul vehicle communications system to feature nationwide vehicle tracking with both a voice and data link. BT Tymnet will support the nationwide data requirements. CoveragePLUS SYSTEM CoveragePLUS is designed for a broad base of users that need to communicate with their vehicles on a regional or nationwide basis. Subscribers to the service may include firms such as private trucking fleets, common carriers, construction fleets, field service fleets, hazardous waste handlers and government agencies. Due to Motorola's expansive nationwide coverage, combined with BT Tymnet's leadership position in providing network access, CoveragePLUS subscribers can access their drivers in locations across the United States. Users equip their vehicles with a CoveragePLUS radio and data terminal. When turned on, software in the mobile unit logs on to the nearest CoveragePLUS node site which notifies the dispatcher of the vehicle's location. These node sites, and subscriber company dispatch locations, have dedicated connections to the TYMNET Network which links them to the Motorola hub. When a mobile unit moves into a new coverage area, it automatically logs on to that system, and the process repeats itself. Providing nearly seamless coverage for communications, CoveragePLUS is the first system to offer 'real-time' position information as well as an instant two-way link. Tracking, load status, and estimated time of arrival of every vehicle are also features of the system allowing users to better manage their fleet, improve customer service, and increase driver efficiency. BT TYMNET SELECTION Motorola evaluated several networks through an extensive analysis. According to Motorola, the CoveragePLUS contract was ultimately awarded to BT Tymnet because of the ability to deliver a highly reliable and proven network solution at competitive rates. BT Tymnet also has experience installing large networks and could best meet Motorola's accelerated implementation plan. "BT Tymnet understood our needs and provided the best network solution to satisfy them," said Dick Kampa, CoveragePLUS Business Manager. "They were extremely flexible in addressing our unique requirements and played a major consulting role. The TYMNET Network also has many physical points of presence to help meet our budget." ROLLOUT The pilot program has been successful and the contract now calls for BT Tymnet to begin a geographic rollout of supported node sites that will expand to encompass the country. By late 1990, CoveragePLUS is scheduled to blanket all of the major interstate highways in the U.S. and the full implementation of the system will link hundreds of sites. CoveragePLUS is currently being marketed in the trucking industry. BT TYMNET INC. BT Tymnet Inc., an international value-added network supplier, is one of the world's largest providers of public, private, and hybrid network solutions.

XLINKs XLINKs are leased line private access port services for X.25 interfaces at speeds up to 19.2 Kbps (bits per second) and supporting up to 64 virtual circuits. Currently available in over 175 U.S. cities, XLINK Express includes port access, leased line, modems, software, and free data transmission on traffic originating from the XLINK interface. As a basic service, XLINK ports utilize standard X..25 default parameters (i.e. a 128 packet size, packet window equal to 2, LAPB, etc.). BT Tymnet also offers other value-added X.25 services that operate non-default service settings for those users needing to customize their communication lines. "XLINK Express demonstrates BT Tymnet's receptiveness to the marketplace and those customers who desire a bundled service," said Art Parsons, Senior Vice President, Sales and Marketing for BT Tymnet. "XLINKs are best configured in a host-to-host environment where users can take advantage of the traffic insensitive pricing," states Joan Carmichael, X.25 services product manager for BT Tymnet. "Customers are now able to choose from a number of X.25 services ranging from full-featured X.25 host interfaces to all-inclusive standard X.25 ports." Prior to XLINK Express, customers requiring a 9.6 Kbps leased line for standard X.25 host connectivity would typically pay an average monthly rate of $1500 for their leased line, modems, and interface. With XLINK, customers can now be charged a flat monthly rate of $900 which includes all the elements they need to successfully connect their X.25 host to the TYMNET network. Depending on communication requirements and the application needs, BT Tymnet customers can save hundreds per month on each XLINK connection. In addition to the new XLINK Express service, for dial-up X.25 users, BT Tymnet has reduced and bundled service pricing on TymDial X.25 private access ports (PAPs). The new pricing includes the X.32/X.25 port access, modem, and kilocharacter transmission originating from the PAPs. TYMDIAL(TM) X.25 TymDial X.25 is an error-free synchronous transmission protocol that provides dial-up X.25 access via the CCITT X.32 and X.25 recommendations. TymDial X.25 allows users to access X.25, asynchronous, QLLC, and DSP applications through dial-up lines rather than more expensive leased lines. TymDial is especially suited for customers needing occasional data communications to remote U.S. and foreign locations where dedicated leased line services become too cost-prohibitive. BT TYMNET INC. BT Tymnet Inc., a wholly owned subsidiary of British Telecom plc, is an international value-added network supplier and one of the world's largest providers of public, private and hybrid network solutions. The company owns and operates the TYMNET network, which offers protocol conversion, error-protection, enhanced security features, electronic data interchange (EDI), card services and electronic messaging.

The agreement is the first step toward international co-operation between BT Tymnet and Radio Austria Communications. Under the agreement, BT Tymnet will operate a node in Austria through Radio Austria Communications under a "one-stop shopping" principle. This local node in Vienna will be directly connected to nodes in Frankfurt and Geneva and will provide BT Tymnet the ability to offer the full range of BT's End-to-End GNS in Austria by January, 1991. This includes dial-up and leased-line access and value-added network services identical to those currently provided in the United States. Radio Austria Communications will also act as a local support center for BT's GNS. SIGNIFICANCE OF THE AGREEMENT "The arrangement with Radio Austria Communications has tremendous significance for both parties," states Mark Baker, President and CEO of BT Tymnet and British Telecom Inc. "The agreement not only provides us the ability to deliver BT's GNS to multinational customers in Austria, but more important, it allows us direct access to expanding BT's GNS to Eastern Bloc countries as well." FURTHER COOPERATION The agreement is the first in a number of possible steps toward international cooperation between BT Tymnet and Radio Austria Communications and the provision of managed data network services. Other steps include: expansion of GNS services to Eastern Bloc countries, the establishment of a direct local sales and support staff for BT's GNS to local multi-national corporations, and the operation, by Radio Austria Communications, of a domestcmanaged data network service. In addition, Radio Austria Communications is in the process of establishing a high-capacity, private, leased-line domestic network to resell bandwidth to customers. Potential synergies between this network and BT's TYMNET Global Network could mean sharing capacity of Radio Austria Communications' private network to provide long distance, leased-line access services to BT and BT Tymnet customers who require increased bandwidth for specific applications and services. RADIO AUSTRIA COMMUNICATIONS Radio Austria Communications is a government-owned telecommunications company providing public telecommunications services such as telegram, telex, packet switched data, leased circuits as well as valued-added services like MHS (electronic mail, X.400), gateways between different telematic services, and EDI/EDIFACT. The company serves customers worldwide, particularly in Austria, China, Eastern Europe and the United States. In early 1991, Radio Austria Communications is to operate and market a nationwide redundant digital value-added network offering bit rates from 2.4 Kbps to 1,544 Mbps. # # # ------------------------------------------------------------------------------- BRITISH TELECOM ANNOUNCES FRAME RELAY FOR TYMNET GLOBAL NETWORK Reveals Broadband Migration Strategy WASHINGTON, D.C., January 29, 1990 -- British Telecom detailed its course today for providing global, broadband data networks. The initial phases of the high speed network will incorporate frame relay software interfaces into the TYMNET Global Network (TGN). First customer services will be available in the second quarter of 1991 and offered initially in the United States, followed by the UK, Europe and the Pacific Rim. Broadband Migration Strategy British Telecom's frame relay strategy for the TYMNET Global Network is to provide a consistent migration path to the Broadband ISDN (B-ISDN)/ATM (Asynchronous Transfer Mode) networks of the future. As the first step toward the new technologies, BT will deploy frame relay as an access interface. With further enhancements to backbone network sites utilizing the Turbo Engine, BT's high-end packet switch, British Telecom will meet the growing customer need for higher speed and bandwidth connectivity for remote LAN interconnections, FAX, electronic image transmission and conference video. The complete migration strategy will be implemented in the TYMNET Global Network over the next three years. British Telecom's Commitment "The future of networking is digital and our migration plans support the easiest, most cost-effective transition to that world as possible. We're committed to providing a global, standards-based, value added network solution to our customers. British Telecom is one of the leading companies in the industry and has demonstrated the experience and presence to deliver the network of the future to the desktops of the world," said Mark Baker, President and CEO of BT Tymnet. Development Offers New Features The first stage of BT's network development will create a "hybrid" frame relay backbone to transport both current TYMNET-II internodal protocol and frame relay traffic. This frame relay software interface will statistically multiplex user data and provide the basis for a frame relay-based LAN interconnect service. Available in the United States during second quarter of 1991, features of this service include Permanent Virtual Circuit (PVC)-based frame relay connections, static frame relay routing and is supported on both current Engine and Turbo technology. Stage two of the development will launch a wideband frame relay backbone capable of transporting node code traffic over frame relay. Available in 1992 and operating exclusively on Turbo Engines at T1/E1 speeds, the features of the service include Switched Virtual Circuit (SVC)- based frame relay connections, dynamic routing, and TCP/IP TELNET gateways. LAN interconnect service allows communication among routers connected via X.25 and routers connected via frame relay. The third stage will be a broadband backbone for the TYMNET Global Network, operating at speeds of T3/E3 and featuring higher throughput and lower delay with the ability to transport isochronous traffic. This broadband backbone, anticipated in the second half of 1994, allows flexible capacity upgrades of both access interfaces and the backbone as needed. _______ ------------------------------------------------------------------------------- BRITISH TELECOM'S CONCERT DEMONSTRATES FIRST EVER FORUM-DEFINED INTEROPERABILITY INTERFACE WITH UNGERMANN-BASS Additional Demonstration of Interoperability Between Concert and Timeplex And Announcement of Intention to Support SNMP Within Concert January 29, 1991 -- Washington D.C. -- Concert, British Telecom's platform for advanced network management, demonstrates support for both OSI interfaces and proprietary protocols in live interoperability demonstrations at the Communication Networks '91 exhibition in Washington D.C. (January 29-31, 1991). In addition, British Telecom announces its intention to provide support for SNMP within Concert to offer customers a migration path from existing protocols. The demonstrations are based on a live network which is managed by the cornerstone of British Telecom's Concert program* - the Concert Integrated Management System (IMS). The Concert IMS is linked to an Ungermann-Bass Access/One wiring enclosure via the recently announced NetDirector LAN management system. The Concert IMS is also linked to Timeplex multiplexers. For the Ungermann-Bass demonstration, the Concert IMS receives information from NetDirector. Live alarms from an Access/One wiring enclosure are relayed to NetDirector, which then passes a Network Management Forum-defined message over an X.25 link to the Concert IMS. This is the first ever demonstration of multivendor interoperability utilizing Network Management Forum Release 1 specifications. Roger Bertman, vice-president of marketing at Ungermann-Bass, said: "Ungermann-Bass is pleased to participate with our OSI partner British Telecom in this powerful demonstration of network management capability for the future." Martin Cassidy, British Telecom LAN business manager commented: "The demonstration shows British Telecom's clear intent to work with its partners to provide customers with the benefits of end-to-end management solutions based on open principles. The Communication Networks demonstration is the first fruit of the OSI development agreement between British Telecom and Ungermann-Bass announced in April 1990." The Concert/NetDirector demonstration illustrates the ability of Concert to share information with element management systems from other vendors using OSI management interfaces, although these systems may themselves be proprietary or SNMP-based. Plans to extend SNMP access direct to the Concert IMS will be detailed later this year. The Timeplex interoperability demonstration shows live management of Timeplex multiplexers. The n twork management protocols used are currently proprietary and are translated into the OSI - based protocols and definitions used internally by CONCERT via specially designed Access software on the CONCERT IMS. This software can also enable interfaces to other proprietary protocols. Keith Willetts, the British Telecom executive behind Concert and also chairman of the Network Management Forum, commented on the developments: "Today's demonstrations are a significant first for customers looksng fo products delivering the open solutions of the 1990s. British Telecom is committed to a major program of Cooperative Networking in its global portfolio. The demonstrations of multivendor network management are good examples of this approach in practice. CONCERT is utilizing not only open systems interfaces, but is also supporting other industry interfaces through a series of cooperative alliances with major vendors." Management of British Telecom's Tymnet Global Network and UK digital circuits complete the CONCERT demonstration at Communications Networks '91. The Concert IMS is undergoing conformance testing in line with Network Management Forum 1.1 specifications. It was the first product to undergo Network Management Forum beta testing. Customer trials for the CONCERT IMS are currently taking place. * CONCERT is British Telecom's name for the network management capability it is building to internationally agreed open standards. It implements Release 1 of the Network Management Forum specifications announced in June 1990. The Concert IMS heads a broad portfolio of British Telecom products and services that will offer open network management through the Concert capability. The Concert IMS is built on an open computer platform using a Posix - conformant operating system. It utilizes the powerful Oracle database to store management information, and X. 11 windows interface to give high definition graphical user interface. The Communication Networks '91 demonstration uses a SunSparc workstation, but the software can be transferred to other compatible hardware platforms. The system can form part of an in-house solution to network management or be used by service providers to manage a client's network. ------------------------------------------------------------------------------- BT NORTH AMERICA TO BUILD PRIVATE NETWORK FOR CANADIAN EMPLOYMENT AND IMMIGRATION COMMISSION ANAHEIM, California, June 4, 1991 -- BT North America Inc. today announced that it will build a private network for the Canadian Employment and Immigration Commission (CEIC). The contract is worth $7.1 million ($8.3 million Canadian) over five years. The network, called CEINET, represents a number of firsts for BT North America. It will be the first TYMNET(r) private network wholly within Canada. CEINET will be one of the first to implement the new generation of TYMNET hardware- the Turbo and PXL Engines. CEIC will be the first in Canada to use BT North America's Concert Data Manager(tm)1000 for open network management capability. Also, BT North America has developed a Burroughs Poll Select (BPS) interface specifically for CEIC. CEIC CEIC is the branch of the Canadian government responsible for unemployment insurance, employment and management of immigration. The current proprietary CEIC network connects remote terminals via multi-drop leased lines to Unisys hosts. The primary applications are; on-line insurance supporting unemployed workers; NESS, an information system designed to provide faster service and more accurate information to CEIC's worker and employer clients; and FOSS, a system that streamlines the management of immigration information and makes the data readily available. Within CEIC there are several distinct networks including on-line Insurance and Employment, which have four regional networks, and Immigration, which employs a national network. Having these independent networks resulted in a high demand for hardware resources and presented a considerable opportunity for consolidation. CEIC also recognized the fact that they needed to improve their telecommunications back-up capability. "The new network will allow CEIC to establish the technical infrastructure necessary to advance our telecommunications capabilities while simultaneously improving our unit costs." said Steve Connolly, Director General of the Information Systems Branch at CEIC. "BT North America was chosen via a competitive process because they were able to provide the best technical solution at the lowest cost," added Connolly. According to CEIC, the primary reasons for selecting BT North America were: - TYMNET's open architecture allows independence from a mainframe vendor. - Ability to support non-standard protocols (BPS). - Integrated network management- available on a regional basis. - Ability to switch hosts (telecommunications backup). - Ability to support newer technologies (LANs). - Cost-effectiveness. "For BT, whose mission is to become the most successful worldwide telecommunications group, this contract marks a significant milestone," said Mark Baker, president and CEO of BT North America. "CEINET represents the most up-to-date TYMNET private network utilizing some of our newest technology, from protocol support and hardware to network management," added Baker. DEPLOYMENT OF THE PRIVATE NETWORK The CEIC private network will be deployed in two phases. Phase One will encompass Ontario and Quebec and will provide access for over 5,000 terminals. Based on the requirements of each site, CEINET will utilize nodes from the complete range of TYMNET Engine family hardware. The Turbo Engine 4800, BT North America's high-end, open system architecture communications processor, will be installed at CEIC hub sites in Montreal, Hull, Belleville and Toronto. These hubs, which have Unisys host computers (except for Toronto), will be connected via 56 Kbps links. Another eleven cities will be equipped with PXL Engines, a high-performance desktop node, and linked to the nearest hub site with two or more 19.2 Kbps or 9.6 Kbps lines. There will be a total of 119 PXLs in CEINET (PXLs will also be co-located with the Turbo Engines at the hub sites). For redundancy, London, Ontario, will have two Compact XL Engines, an intermediate size node in a TYMNET network. Management of the network will be handled from CEIC headquarters as well as the regional computing centers in Belleville and Montreal. It will be provided through BT North America's Concert Data Manager 1000, an open network management capability built on internationally-agreed standards. Additionally, CEIC will run their own in-house trouble ticket system by integrating the BT Service Desk into the Concert Data Manager. "We welcome the opportunity to work with the Canadian government to enable them to provide better and more cost-effective services to their clients," said David Kingsland, General Manager of BT Canada. The Phase Two national expansion will bring the benefits of open systems architecture to CEIC. Where Phase One will be native mode, the second phase will use the PXLs at the terminal interface for BPS protocol conversion. This expansion phase will add approximately another 7,000 terminals to the network. BT NORTH AMERICA INC.
