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
20402, Stock NO. 004-000-00345-4.
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.
iii
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.

CHAPTER 1：TAINET MODEM INTRODUCTION
1.1 Description
•The TAINET Network Series Modem T-336Cx/Nx/NDx are high performance,
synchronous and asynchronous, full duplex multi-standard modems designed for
use on 2-wire dial circuits and 2/4 wire leased lines.
The MODEM series fully comply with ITU-T V.34、V.32bis/V.32、V.22bis、
V.22、V.23、V.21 and BELL 212A/103，speed: 115200 - 300bps Asynch，
33600 - 1200bps Synchronization。
In V.34 and V.32bis/ V.32 modes, echo concellation provides 2-wire full
duplex operation over all PSTN circuits including those with satellite sections.
Compatibility is also provided with Bell 212A and Bell 103 operating standard.
•V.34 mode provide full duplex operation at up to 33.6 kbps speed, with line
probing, symbol rate and carrier frequency selection technologies.
•V.34 mode also use other advance technologies such as Adaptive Precoding, Non-
Linear Encoding (Warping), Constellation Expansion, Multidimensional Trellis
coding and Shell Mapping ,Tx power back off(Power Reduction).
•There are 10 factory default profiles and 10 user's profiles for your easiest
configuration setting.
•Allow up to 16 modem cards (T-336Nx) with 16 port on a rack shelf (TRS-16).
•Allow up to 16 modem cards (T-336NDx), with 32 port on a rock shelf (TRS-32).
•A 2 by 16 characters LCD display on the front panel with back lighted control for
configuration set-up and monitoring conveniently.
•Line status monitoring including transmit/receive signal level, S/N ratio, EQM (eye
quality monitoring), signal quality, frequency shift, delay, echo, retrain count,
phase jitter, Tx/Rx baud rate, Tx/Rx carrier frequency, Tx/Rx DCE speed, TX
power back-off ..., etc.
•Front panel lock and password protect features prevents from the operation of
unauthorized person.
•Enable remote configuration through secondary channel.
•V.13& V.23 simulated carrier control for half duplex application.
•2 wires or 4wires automatic or manual dial back-up and restore.
