Accessory Kit
A Wireless MultiModem Accessory Kit is
available. Generally speaking, it is useful to
have one or two kits to configure a group or
fleet of Wireless MultiModem units
(generally, you will not need one kit for every
modem). The kit includes an antenna, a
power supply and a product CD. The product
CD contains an AT Command manuals, other
documentation, and modem software.

Product Description
AT Command Info
This manual describes a minimal set of AT
commands that are adequate for configuring
many common application situations. A
complete set of AT command definitions can
be found in the AT Command manuals (one
for GSM/GPRS and one for CDMA). These
manuals are available on the MultiTech web
site or on the Accessory Kit CD.
Phone Number for the Wireless Modem
· Every wireless modem will have its own
unique phone number.
· The wireless modem’s phone number may
simply be told to the subscriber or be on the
SIM or both. Wireless provider
implementations may vary.
Network Access
The network access arrangements to be
specified in Windows Dial-Up Networking (of
the computer that the wireless modem is
serving) will vary according to the type of
wireless service used.
10
Product Description
· For GSM-without-GPRS, a circuit-
switched data connection is used. The
user can set up DUN to make a
conventional V.32 modem connection to
any terminating modem at the other end.
The phone number specified in DUN can
be one supplied by the wireless service
provider or another phone number
related to a different dialup modem
service (e.g, a dialup modem service
phone number from any commercial or
private dialup network).
· For GSM-with-GPRS, a single DUN
number is generally used by all of a
wireless provider’s subscribers
throughout its area of coverage (regional,
nationwide, continental, etc.). Rather than
being a literal phone directory number, as
in conventional DUN, this is a code that
gives the modem Internet access.
