FCC REQUIREMENTS
This equipment complies with Part 68 of the FCC Rules. On the base unit of this
equipment is a label that contains, among other information, the FCC Registration
Number and Ringer Equivalence Number (REN) for this equipment. IF REQUESTED,
THIS INFORMATION MUST BE GIVEN TO THE TELEPHONE COMPANY.
The REN is useful to determine the quantity of devices you may connect to your
telephone line and still have all of those devices ring when your telephone number is
called. In most, but not all areas, the sum of the REN's of all devices connected to one
line should not exceed five (5.0). To be certain of the number of devices you may
connect to your line, as determined by the REN you should contact your local
telephone company to determine the maximum REN to your calling area.
If your equipment causes harm to the telephone network, the telephone company may
discontinue your service temporarily. If possible, they will notify you in advance. But
the advance notice isn't practical, you will be notified as soon as possible. You will be
informed of your right to file a complaint with the FCC. Your telephone company
may make changes in its facilities, equipment, operations or procedures that could
affect the proper functioning of your equipment. If they do, you will be notified in
advance to give you an opportunity to maintain uninterrupted telephone service.
If you experience trouble with this telephone equipment, please contact the following
address and phone number for information on obtaining service or repairs.
The telephone company may ask that you disconnect this equipment from the network
until the problem has been corrected or until you are sure that the equipment is not
malfunctioning.
This equipment may not be used on coin service provided by the telephone company.
Connection to party lines is subject to state tariffs.

INFORMATION TO THE USER
NOTE: This equipment has been tested and found to comply with the limits for a
Class A digital device. Pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and if not installed and used in
accordance with the instructions may cause harmful interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on.
The user is encouraged to try to correct the interference by one or more of the
following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This booklet is available from the US government Printing Office, Washington, DC

The shielded RS-232 cable is to be used in order to ensure compliance with FCC Part
15, and it is the responsibility of the user to provide and use shielded RS-232 cable
from MODEM to personal computer.
CAUTION: Any changes of modifications not expressly approved by the grantee of
this device could void the user's authority to operate the equipment.

CHAPTER 2 INSTALLATION
2.1 Description
This chapter provides the information needed to install the TAINET Network Series
Modem and to ensure that it is working properly. You may obtain more information
about this subject for rack-mount modem shelf from the User's Manual of TAINET
rack-mount modem shelf.
2.2 Unpacking
Save the carton and protective packing material in which your TAINET Network
Series Modem was shipped; you might need them for repackaging if you have to store
or ship the modem in the future. The following items are shipped with your TAINET
Network Series Modem:
 One User's Manual for TAINET Netwok Series Modem.
 One 7-feet (2.13m) modular telephone cable for connection to an RJ45 8-pin jack.
 One 7-feet (2.13m) modular telephone cable for connection to an RJ11 4-pin jack.
 One 8-pin box for leased line application.
Rough handling during shipping causes most early modem failure; after you unpack
the modem, check carefully for shipping damage. Contact the shipper if you notice
any damage.
Direct any additional questions about damaged or missing parts to the nearest sales
representative, or contact:

2-2 INSTALLATION
2.3 Site Requirements
The FCC requires telecommunications equipment to withstand electrical surges
which may result from lightning strikes; the TAINET Network Series Modem meet
the requirements set forth by the FCC. The following procedure outlines some
common practices which can minimize the risk of damage to computer equipment
from electrical surges.
1) Make sure the electrical service in your building is properly grounded as described
in article 250 of the National Electrical Code (NEC) handbook.
2) Verify that a good copper wire of the appropriate gauge, as described in Tables
250-94/95 of the NEC Handbook, is permanently connected between the
electrical service panel in the building and a proper grounding device such as:
A ground rod buried outside the building at least 8 feet (2.44 meters) deep in
the earth.
Several ground rods, connected together, buried outside the building at least 8
feet (2.44 meters) deep in the earth.
A wire (see tables 250-94/95 of the NEC handbook for gauge) that surrounds
the outside of the building and is buried at least 2.5 feet (.76 meters) deep in
the earth. Note: The three grounding devices described above should be
firmly placed in the earth. Soil conditions should not be dry where the device
is buried.
A metal water-supply pipe connected to the water main in the street or a
metal cased well. The water pipe used must not have plastic piping between
the ground connection and the water main (or the well). The connection should
be made where the pipe enters the building. The water meter must be shunted
by a copper strap.
3) If you are unsure whether the electrical service in your building is properly
grounded, have it examined by your municipal electrical inspector.
4) Install a surge protector between the modem and AC power outlet. Any
additional computer equipment you have connected to the modem (directly or
through another device), such as a terminal or printer, should also be plugged
into the same surge protector. Make sure that the surge protector is properly rated
for the devices you have connected to it.
5) Call your telephone company and ask them if your telephone line is equipped
with a circuit surge protector.
6) If you are operating the modem in an area where the risk of electrical surges form
lightning is high, disconnect the modem form the telephone line at the modem's
rear panel when it is not in use.

INSTALLATION 2-3
2.4 Site Selection
Locate the TAINET Network Series Modem no farther than 50 feet (15.24 meters)
from your data terminal equipment (DTE) and within 6 feet (1.83 meters) of a
grounded AC outlet furnishing the required power.
Install the modem in a clean area that is free from environmental extremes. Allow at
least 6 inch (15.24 cm) in front of the modem for access to the front panel, and at
least 4 inch (10.2 cm) in back for cable clearance. Position the modem so you can
easily see the front panel. Do not stack the TAINET Network Series Modem on top of
another modem.
*CAUTION: To avoid overheating the TAINET Network Series Modem, do not place
anything within 1 inch (2.54 cm) of either side of the modem, and do not place the
modem on its side.
2.5 AC Electrical Outlet Connection
Check the label on the bottom of the modem for the unit's power requirements. Once
you are certain the power requirements specified on the label match those of your
electrical outlet, plug the power cable into the outlet.
Once the TAINET Network Series Modem is installed as described in the previous
sections, you may turn the power on. The modem performs a self-test before the
TAINET Network Series Modem greeting message appears on the liquid crystal
display (LCD) on the modem front panel.
