Chapter 1 – Introduction and Product

Description

Introduction

This User Guide describes the CallFinder ® Cellular Gateway: the CF100FX2-G; a GSM model with connectors

for both the FXS and FXO telephony interfaces.

The CallFinder cellular gateway connects to a PBX trunk line, a PBX extension line, or to a single PSTN (POTS)

line. It routes incoming and outgoing calls through the wireless network. Users can take advantage of the lower

costs that cellular networks offer under certain circumstances (like free calling between cellular phones from the

same provider, and free/reduced costs for weekend and night-time calls initiated on cellular phones). The

CallFinder can also be used to bring phone service to an area where land lines are not available or for

emergency access to the cellular network from a PBX.

Interfaces, Activation, & Configuration

The CF100FX2-G will connect to either an FXS or FXO interface; FXS is the default factory setting. The

CF100FX2-G is activated by inserting a SIM from a cellular provider; no AT commands are required for this.

Configuration is done through Multi-Tech specific AT commands.

Safety Warnings

Handling Precautions

All devices must be handled with certain precautions to avoid damage due to the accumulation of static

charge. Although input protection circuitry has been incorporated into the devices to minimize the effect of

this static build up, proper precautions should be taken to avoid exposure to electrostatic discharge during

handling and mounting.

Caution: Maintain a separation distance of at least 20 cm (8 inches) between the

transmitter’s antenna and the body of the user or nearby persons. The modem is not

designed for, nor intended to be, used in applications within 20 cm (8 inches) of the body

of the user.

Safety Recommendations for Rack Installations

•Ensure proper installation in a closed or multi-unit enclosure by following the recommended installation as

defined by the enclosure manufacturer.

Chapter 2 – Getting Started

Step 1. Obtain a Wireless Account

Obtain a GSM Network Accoun

1. Contact your GSM network agent to obtain an account and/or SIM card. Be sure to specify if you

want a data only, voice only or voice and data account.

2. Provide the agent with the CallFinder’s model number and IMEI number. Both are located on the

label on the bottom of the product. You will also need to provide information about billing and about

the wireless services/features you need.

3. After Activation, your agent or wireless provider will give you the following:

∗a SIM card, and

∗a phone number.

4. Install the SIM Card.

Note: The wireless CallFinder requires a SIM card (Subscriber Identity Module) to operate on a GSM

network. The GSM CallFinder will not operate without a SIM.

To install the SIM card:

∗Use a small screwdriver to remove the screw closest to the outside edge of the modem. Then

swing the loosened SIM slot cover up and over to the left.

∗Insert the SIM card into the SIM card slot. A small, needle-nosed plier may be useful for this.

The following graphic illustrates the correct SIM card orientation.

∗Verify that the SIM card fits properly; then replace the cover.

Chapter 2: Getting Started
