Before Using Data Communication
About the Operating Environment
Operating environment of a PC to be used for data
communication is as follows.
Item Required environment

※ 2
5MB or more free space
Display High color (65,536 colors) and high resolution
(800
× 600 dots) or over (recommended)
※ 1 Operation on a PC running upgraded OS is not guaranteed.
※ 2 The required memory and hard drive capacity may vary
depending on the PC system configuration.
Other Necessary Items
Other than the FOMA terminal and a PC, the following
hardware and software are necessary.
 FOMA USB Cable (optional) or FOMA USB Cable with Charge
Function 01 (optional)

Supplied CD-ROM “FOMA SO703i CD-ROM”
● This manual assumes that you use the FOMA USB Cable
(optional).
● Purchase the exclusive “FOMA USB Cable” or “FOMA
USB Cable with Charge Function 01”. A generic USB
cable for a PC connection cannot be used because it has
a different connector shape.
■ Definition of terms
● Administrator
An administrator is authorized access to all Windows
XP and Windows 2000 Professional systems. At least
one user with Administrator privilege is set for each PC.
Normally, a user without Administrator privilege cannot
install the communication configuration files (drivers). For
more information on Administrator privilege, contact the
manufacturer of your PC or a representative of Microsoft
Corporation.
● APN (Access Point Name)
A character string used for identifying the Internet service
provider host or in-house LAN for packet communication. For
example, the APN of “mopera U” is “mopera.net”.
● cid (Context Identifier)
A registration number available when you save a packet
communication host (APN) in the FOMA terminal. You can
save up to 10 numbers from one to 10 for the FOMA terminal.
Default cid of the FOMA terminal
Registration number (cid) Host (APN)
1 mopera.ne.jp (mopera)
2 Undefined
3 mopera.net (mopera U)
4-10 Undefined
● DNS (Domain Name System)
DNS is a system that converts a domain name (example:
nttdocomo.co.jp) into an IP address, which is used by a PC.
● IrDA (Infrared Data Association)
I r D A i s a n o r g a n i z a t i o n t h a t e s t a b l i s h e s i n f r a r e d
communication-related standards.
● IrMC (Ir Mobile Communication)
Standards established for the purpose of data transfer
between mobile phones and between PDAs (personal digital
assistant). You can exchange phone numbers and schedule
data between mobile phones or PDAs equipped with an
IrMC-compliant infrared jack.
●
OBEX (Object Exchange)
OBEX is one of the global standards for data communication.
You can exchange data between OBEX-compliant mobile
phones, PCs, digital cameras, and printers.
● QoS (Quality of Service)
Service quality technology that enables the user to use a
communication line in accordance with requirements. If you
are using the FOMA terminal, you can set the communication
speed for connection.
● W-TCP
TCP parameter that makes optimal use of TCP/IP transmission
capabilities for packet communication on the FOMA network.
To take full advantage of the communication performance of
the FOMA terminal, you must perform this communication
settings.
