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 f or configuring many common application situations. A complete set of AT command definitions can be found in the CDMA AT Commands Reference Guide. This manual is 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.

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.

• For point to point data, 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 CDMA 1x data, 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.
