XE924M Base Access Point for Multiple Remote Machines

Description

Xecom combines proven embedded modem technology

and a 900 MHz transceiver in the XE924M, Base Access

Point. The Base Access Point is a simple scheme to

connect up to 128 remote systems to a single dial-up

telephone line. Each remote system communicates with

the Base Access Point using Xecom’s XE900M Smart

Transceiver. The XE924M eliminates hardware

redundancy, and therefore reduces both the initial

investment and operating costs.

Xecom’s Base Access Network significantly reduces

hardware costs in locations with multiple systems. For

example, credit card verification normally requires a

dedicated modem and telephone line for each sales

terminal. Each time a terminal is added another modem

and another telephone line also need to be added. The

Base Access Point connects all of the terminals through

one shared modem and telephone line. The only

hardware requirement is the addition of an XE900M

Smart Transceiver to the terminal equipment.

This scheme eliminates the installation requirements of

a wired network. Whether you add a system equipped

with a Smart Transceiver to the network or build a new

facility, the 900 MHz wireless link eliminates the need to

install cables and configure a server. By virtue of its

commonality with millions of cordless telephones the

XE924M also offers the most cost effective wireless

link available.

The XE924M reduces hardware costs in multiple

system environments. Systems which now require a

dedicated modem and telephone line for each unit

can be connected through the shared modem and

telephone line.
