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.

SDTU-01 SDSL V.35 DSU

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

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.

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.

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.
