|
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.
|
||

|
||
|
|
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.
|
||
|

|
||
|
|

|
||
|
|

|
||
|
|

|
||
|
|
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
|
||
|
|

|
||
|

|
|
----------------------------
|
||
|
|

|
||
|
|

|
||
|
|
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
|
||
