CallFinder Operation

The CallFinder brings analog DID services to a key telephone
system or PBX that is not DID-enabled.

Prerequisite: Ordering the DID Lines

To operate the CallFinder system, you will need one or two DID
(Direct Inward Dial) lines in your office. You must order the DID
lines from your local telephone operating company (telco). A
DID line allows one phone line to be associated with multiple
directory numbers. However, only one call can occur on this line
at any given time.

DID lines are sold in groups. For example, a telco in New York
City might offer a DID line with a set of 10 directory numbers in
the range of 212-555-4100 through 212-555-4109.

When ordering your DID line, ask the telco representative for
these details about the DID service. These details will be
important when setting up your CF220-DID unit.

Cabling Instructions

Summary: Place the CallFinder in a convenient location, and

then connect it to earth ground, to your AC power outlet, to your
Ethernet network, and to your telco DID service. You cannot
connect the CallFinder's Extension Ports (FXS/FXO) to your
PBX until after you have configured the CallFinder software. In
the CallFinder software, you will configure the Extension Ports
as either FXS or FXO, and this must be done before they can be
connected to your PBX.

Connect CallFinder to Earth Ground

Connect the CallFinder’s ground connector to a true earth
ground (the ground of your building’s electrical system).

Grounding connectors

must be secured

permanently to

product ground screw

and earth ground screw.

Connect CallFinder to Power

Insert the 9 Vdc power connector into the CallFinder’s power
receptacle and fasten it with the lock nut. Connect the female
end of the AC cord to the power block. Then plug the AC cord
into the power outlet.

Caution: Use only the 9 Vdc power transformer supplied with

the CallFinder. Use of any other transformer voids
the warranty and can damage the CallFinder.

Verify powering.

After power is applied, the PWR LED comes on immediately but
there is a 4-second delay before the

Status LED comes on. In

normal operation, the

Status LED will be flashing.

When you apply power, the CallFinder performs a diagnostic
self-test. The

Status indicator flashes when the embedded

processor is up and running. If the

Status indicator does not

flash, check that the power supply is solidly connected and that
the AC outlet is live.

Connect CallFinder to Ethernet Network

Plug one end of your RJ45 Ethernet cable into the CallFinder’s
Ethernet jack (labeled “10/100”) and the other end into your
network Ethernet hub. This Ethernet cable is not included with
your CallFinder unit.

Note: Before connecting to the Ethernet Network, make sure

that the network to which you are connecting the
CallFinder is not a 192.168.2.x subnet.

MultiTech Systems, Inc. 9

CallFinder Cabling Guide

If it is a 192.168.2.x subnet, it may clash with the

CallFinder because the CallFinder’s default IP address
is 192.168.2.1. To remedy such a situation, connect
directly from the Admin PC to the CallFinder using an
RJ45 cable until the CallFinder’s IP address has been
configured. Thereafter, connect the CallFinder into the
network.

Connect CallFinder to DID Lines

Plug one end of the phone cable into the CallFinder’s Channel 1
DID jack and the other end into an analog DID trunk line jack.
The DID Line cable is included with your CallFinder.

Caution: Never plug the DID connector into a standard POT S

Line. This may damage the CallFinder or the central
office equipment. Use only an analog DID Line.

Repeat for the CallFinder’s Channel 2 DID port.

Identify CallFinder’s Extension Ports (FXS/FXO) for Later
Hookup

Caution:

You must wait until after the CallFinder software has

been configured before connecting the cables
between the CallFinder’s Extension (FXS/FXO) Ports
and the PBX. Because the CallFinder and the PBX
can both supply battery power, the cable connections
must be done properly. Otherwise equipment
damage could occur.

Before making connections to the CallFinder Extension
(FXS/FXO) channels, you must know the type of PBX port to
which each CallFinder port will be connected and set the
“Extension Port” field in the CallFinder

Channel Configuration

screen appropriately.

When connecting to a PBX Station Port,
set the CallFinder channel to FXO.

When connecting to a PBX Trunk Port,
set the CallFinder channel to FXS.

When the Channel Configuration | Extension Port software
field has been set properly for both CallFinder channels, you can
proceed to connect the cable between each of the CallFinder’s
FXS/FXO ports and the corresponding PBX port.
