SDTU-01 SDSL V.35 DSU

Overview
The SDTU-01 SDSL DSU with V.35 interface is a data access DSU
modem with the latest multi-rate SDSL (Symmetrical Digital Subscriber
Line) technology offering both long range and high speed data
transmission with rates from 144Kbps up to 2320Kbps. The
transmitting data rate may be adapted for the best "rate vs. range"
performance for efficient and stable data transmission.
The SDTU-01 uses the 2B1Q line code with echo cancellation to
transmit its high data rate over a single twisted pair of telephone wire
without being affected by bridge taps or mixed cable links. It also
provides high immunity to background noise and enables transmission
over multiple pair cables.

Important Safety Instructions
The following safety instructions apply to the SDTU-01:
1. Be sure to read and follow all warning notices and instructions.
2. The maximum recommended ambient temperature for SDTU-01 is
40(104) Care must be taken to allow sufficient air circulation or
space between units when the SDTU-01 is installed inside a closed
rack assembly. The operating ambient temperature of the rack
environment might be greater than room temperature.
3. Installation in a rack without sufficient air flow can be unsafe.
4. Racks should safely support the combined weight of all equipment.
5. The connections and equipment that supply power to the SDTU-01
should be capable of operating safely with the maximum power
requirements of the SDTU-01. In the event of a power overload, the
supply circuits and supply wiring should not become hazardous. The
input rating of the SDTU-01 is printed on the nameplate.
6. The AC adapter must plug in to the right supply voltage, i.e. 120VAC
adapter for North America and 230VAC adapter for Europe. Be sure
the supplied AC voltage is correct and stable. If the input AC voltage is
over 10% lower than the standard may cause to malfunction of the
SDTU-01 unit.
7. Installation in restricted access areas must comply with Articles 110-16,
110-17, and 110-18 of the national Electrical Code, ANSI/NFPA 70.
8. Do not allow anything to rest on the power cord of the AC adapter, and
do not locate the product where anyone will walk on the power cord.
9. Do not service the product by yourself. Opening or removing covers
can expose you to dangerous high voltage points or other risks. Refer
all servicing to qualified service personnel.
10. General when installed in the final configuration, the product must
comply with the applicable safety standards and regulatory
requirements of the country in which it is installed. If necessary,
consult the appropriate regulatory agencies and inspection authorities
to ensure compliance.

11. A rare condition can create a voltage potential between the earth
grounds of two or more buildings. If products installed in separate
building are interconnected, the voltage potential can cause a
hazardous condition. Consult a qualified electrical consultant to
determine whether or not this phenomenon exists and, if necessary,
implement corrective action before interconnecting the products. If the
equipment is to be used with telecommunications circuit, take the
following precautions:
4 Never install telephone wiring during a lightning storm.
4 Never install telephone jacks in wet location unless the jack is specially
designed for wet location.
4 Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
4 Use caution when installing or modifying telephone lines (other than a
cordless telephone) during an electrical storm. There is a remote risk of
electric shock from lightning.
4 Do not use a telephone or other equipment connected to telephone
lines to report a gas leak in the vicinity of the leak.

Installation
1.
Connect the local loop
(twisted copper pair
telephone wire) to the WAN
port (SDSL, RJ-11) by
using the RJ-11 cable
attached. Be sure this local
loop had been properly
connected to the Central
Office side SDSL
equipment.
2.
Connect the DB-25
connector marked "V.35"
with "DB-25 to V.35" cable
to the router. To correctly
connect with the router
cable. Please refer to the
section of "Cables" for
detail pin assignment. The
other end of router will
connect to LAN (Local Area
Network) or other data
equipment.
3.
Power connection --
• Warning : Do not apply
the AC power before all
the connections above
have been connected.
• Plug in the AC Adapter to
the wall AC socket
• Connect the DC jack to the
DC-IN of the unit

Terminal Connection --
• A data terminal can be
connected to the
TERMINAL port (RS-232)
of the unit for configuration
& monitoring purpose. Use
the RS-232 serial cable to
connect to a ASCII data
terminal. The TERMINAL is
VT-100 compatible.
• A PC with data terminal
emulation software
installed, can be connected
via serial COM port in data
terminal mode.

Hardware Setup
DSL rate and terminal type can be set up by adjusting the 4-pole DIP switch
on the rear panel. Sw. 1 to Sw. 3 are for adjusting the DSL rate while Sw. 4
is for termination type.

Point-to-point Operation
1. The SDTU-01 should be located on each side of the connection. One
side must be set to "CO" and the other side must be set to "RT". Refer
to the section on "Hardware Setup" for the CO & RT setup.
2. Insure that both CO & RT SDTU-01s are set to the same DSL rate. For
example, 784Kbps.
3. Make sure that both CO & RT SDTU-01s have been connected to the
Routers properly.
4. Check the WAN LED on the SDTU-01 -- it will remain lit when the Link
is successfully established. The DSL training process may take around
one minute and the WAN LED will flash during the training process.
5. After the DSL link is established, check the router setup. Both CO & RT
side routers must be set to use the same Link Protocol, i.e. PPP or
Frame Relay link. Both side routers must also set the same
parameters. Otherwise, they may fail to communicate with each other
even though the DSL link is ready.
6. Follow the Router manual to set the IP and other parameters. When
the router is properly set, you are ready to use the high-speed
connection between the two networks. You may test the data
transportation speed by using the "Ping" command or FTP file transfer.
