(202) 429-9660 MCI INTERNATIONAL ----------------- MCI International provides private-line voice service to several overseas countries, and data and message services, including telex, cablegram, leased channel, and packet switching communications, to more than 200 overseas points. MCI has moved into two new areas of service: International direct-dial telephone service and international electronic mail and hard-copy delivery services. International Record Services ----------------------------- TELEX SERVICE (domestic and international) permits instantaneous, two-way, written communications with other subscribers worldwide. Customers can send messages at any time, even though the receiving terminal may be unattended. MCI International offers access to its telex service from a variety of terminals and networks; not only subscribers with telex terminals but also those with communicating word processors, data terminals or computers that communicate over telephone lines can take advantage of MCI International telex service. To subscribers connected to its own telex network, MCI International offers World Message Services--a package of communications offerings including telex, cablegram and MCI Mail services. Various service enhancements are available to save time, improve operating efficiency and simplify records keeping for telex users. CABLEGRAM SERVICE, the traditional means of international written communications, offers flexibility in delivery and economical rates for shorter messages. Cablegrams can be delivered to virtually any overseas point. Subscribers with telex terminals or various other types of equipment can access and TELUS cablegram switch and take advantage of such service enhancements as abbreviated addressing and departmental billing. LEASED CHANNEL SERVICE provides an exclusive line between a U.S. firm and it's overseas office for private communications 24 hours a day. Each MCI International leased channel is tailored to meet the needs of a specific customer for teleprinter, facsimile, voice and/or data traffic. For subscribers with several offices requiring private communications with each other, MCI International offers a versatile message-switching service. Voice/data leases can be configured to meet a whole array of communicating needs; for example, one channel might carry data traffic from a computer at night, voice communications during office hours, and simultaneous teleprinter messages at any time. Data channels can handle requirements for traffic at any speed from 1200 bits per second to 1.544 megabits per second. IMPACS SERVICE uses packet-switching technology to provide international communications service between data terminals and computers. Impacs offers on-line, real-time connections and enables many types of incompatible systems to communicate. Impacs service offers virtually error-free transmission because of the error-detection and retransmission capability of the network. INSTALINK SERVICE allows businesses overseas to use regular telex equipment to access remote computing systems and databases in the U.S. Subscribers can retrieve data from a computer-based information service or use a computing system connecting to a packet-switching network in the U.S. INTERNATIONAL FACSIMILE SERVICE enables subscribers to send duplicates of original documents overseas quickly and efficiently, even when neither the sender nor the receiver has facsimile transmission equipment, or when the sender and receiver have incompatible equipment. DATEL SERVICE provides automatic or voice-coordinated data transmission at speeds up to 2400 bits per second. Either digital or analog facsimile traffic can be transmitted via Datel. Datel facilities are conditioned to ensure high-quality transmission. The MCI International switching center allows communications between incompatible terminals. MARITIME SERVICES provide instant, high--quality contact between ships at sea or offshore rigs, and between these vessels and land-based subscribers worldwide. International Voice Services ---------------------------- PRIVATE LINE SERVICE provides, fast, easy access to a single overseas location at an economical monthly rate. This technically efficient system maximizes the use of line capacity by recognizing idle time and assigning a speaker to a transmission path only when the path is needed. Users can dial a four-digit extension from a regular business phone to reach a key overseas location. International Mail Services --------------------------- WORLD MESSAGE SERVICE subscribers can access the domestic electronic mail and hard-copy delivery offerings of MCI Mail. In addition, MCI International is developing fast, low-cost services that will deliver electronic messages and high-quality printed documents worldwide.
