CAUTION:Any changes of modifications not expressly approved by the grantee of this
device could void the user's authority to operate the equipment.

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: INTRODUCTION
1.1 General Description
lThe TAINET DT-2000 series are High-bit-rate Digital Subscriber Line (HDSL)
systems which deliver 2.048Mbps E1 service to the customer up to 4.5 Km (2.8 miles)
length over four 24 AWG (0.5 mm) lines.
lDT-2000 series, use 2B1Q modulation and support Wetting Current, Power Feeding
fully complies with the ETSI standard ETR 152 provide full and fractional E1, switched
E1 or Nx64K E1 service over two pairs of wires.
lSwitched E1 or N×64K E1 service which is used in Point-to-Point, add-drop
applications such as dial-up video conference, distant learning, and home entertainment,
it also delivers new service such as Switched Multi-Megabit Data Services (SMDS) and
frame relay with speed and economy.
lThe 2B1Q line code is a four-level pulse-amplitude modulation code as shown as Table
1-1. Its power average on a sequence of symbols consist with a frame word in all other
positions is between 13.0 dBm and 14.0 dBm, which over the frequency band from 0
Hz to 1168KHz into a 135 ohms termination.
Binary Digits Quaternary Symbol
First Bit (Sign) Second Bit (Magnitude)
1 0 +3
1 1 +1
0 1 -1
0 0 -3
Table 1-1 The 2B1Q Line Coding
lThe HDSL system consist of Line Termination Unit(LTU) for Central Office (CO) in the
network side, and Network Termination Unit (NTU) for Remote Terminal (RT) in the
user side. It will provide an alternation to repeat E1 lines for buyer to support
repeaterless 2048Kbps rate access over non-loading copper loop.
lSupport either 120 ohms balanced (terminal block) or 75 ohms unbalanced (BNC).
Fractional E1 use one or two loops for data transmission from 64Kbps to 2048Kbps
(N x 64K) of V.35, RS-530, V.36(RS-449) or X.21/V.11 interfaces.
lRack mounted model may apply 16 cards to one shelf. TAINET Network Management
System work over TCP/IP for Windows 9x/NT platform is available.
lRemote configuration will be matched with central site: for general application, users just
need to setup CO and RT to be connected. Once it is connected, the parameters of RT
will follow CO automatically. For example, when CO site setup from Full E1 to
Fractional E1, the RT site will follow up to Fractional E1 too.
