1. FCC Statement
This equipment has been tested and found to comply with the limits for a Class B 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 can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
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 measure:
- Reorient or relocated 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.
- Shielded cables must be used to comply with FCC regulations.
WARNING (Part 15, Section 15.21)
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.

2. Overview
Asymmetric Digital Subscriber Line (ADSL) technology is the latest line coding technology
enabling subscribers to access the network at a high speed through the existing telephone lines. It
provides subscribers with network access services from several tens Kbps up to several Mbps for
the downstream data from the ISP to the subscriber and from several tens Kbps up to 1 Mbps for
the upstream data from the subscriber to the ISP, depending on the physical length of the
subscriber line and the network service contract level with the ISP.
Furthermore, along with new data transferring capabilities, subscribers are also provided with
usual telephone services, as well.
ADSL allows very cost-efficient application services with asymmetric traffic characteristics such
as high-speed Internet access and Video-On-Demand (VOD), by providing services where
downstream data is about 10 times faster than upstream data.
RECSPEED-8000E, RECSOL I&C ADSL modem, is located in the customer premises of the
ADSL-based subscriber network, and allows the subscriber to use actual ADSL services. The
following section describes how to use ADSL services through RECSPEED-8000E.
For the said purpose, it is necessary to understand the entire network architecture. The entire
network configuration diagram is shown in the Figure-1.
Figure-1 ADSL Service Network Configuration Diagram
As shown in Figure-1, RECSPEED-8000E is connected to the ATM backbone network adopted
from B-ISDN by base transmission method through the ADSL, and to the subscriber via
Ethernet. Therefore, it basically requires the function to convert between ATM traffic of the
network and Ethernet traffic of the subscriber.
For the said purpose, RECSPEED-8000E is designed to support the inter working structure for
end-to-end services at Layer 2, for which it executes Ethernet Bridging Function.
For a more specific description of the above, the diagram of entire network configuration in terms
of end-to-end protocol structure is shown in the Figure-2.

3. Introduction
3.1 RECSPEED-8000E overview
RECSPEED-8000E is installed and connect to the customer premises, and enables the users to
access ADSL services, through a convenient menu-driven interface:
1) Access to system status and configuration information,
2) Online software upgrade,
3) Access to and setting of ATM VCC status information,
4) Access to ADSL interface status information,
5) Access to Ethernet interface status information,
6) Bridging function, spanning tree setup and access to status information.
RECSPEED-8000E features two methods of implementing user's interface. A user can connect a
terminal directly to RS-232 serial port of RECSPEED-8000E, or use Telnet through the network
interface.
Upon initial installation of RECSPEED-8000E, however, it is possible only to access the serial
port, since the IP address of RECSPEED-8000E is not assigned yet.
Access to RECSPEED-8000E through the serial port is available with any standard terminal
equipment at the speed of 9,600 baud rate.
3.2 Components
Unpack the package of RECSPEED-8000E and verify that the following components are
included. There should be following components (Refer to Figure-3).
1) RECSPEED-8000E main body 1 set
2) Ethernet cable (cross-connect) 1 ea
3) Telephone cable 1 ea
4) DC power Adapter 1 ea
5) Cable for DC power Adapter 1 ea
6) Micro filter 2 ea

3.3.1 Front panel
Figure-4 shows LEDs that are equipped on the front panel of RECSPEED-8000E.
Figure-4 Front panel of RECSPEED-8000E
RECSPEED-8000E has four LEDs as shown in the figure above, which instantaneously indicate
the modem status as described below:
ON
(Green) Indicates the connection to the power supply. This LED is on when power is
provided.
LINK
(Green) The LED indicates that the link status of ADSL. It blinks while the link is
attempted, and remains on once the link is established.
DATA
(Green) The LED indicates data is transmitted over ADSL. That is, it blinks whenever
data is received or transmitted over the ADSL.
LAN
(Green) The LED indicates the connection status of Ethernet. It remains on as long as the
physical connection is established normally.
3.3.2 Rear panel

Figure-6 Cabling
4.2 Installation and operation preference
If the cable installation is completed, supply the power for the PC and RECSPEED-8000E. If the
terminal emulation program such as hyper-terminal is executed, the prompt that requests the
password input is displayed on the screen.
When the RECSPEED-8000E is produced, the password is set up as “8000E” for delivery.
Therefore, if this password is entered, RECSPEED-8000E can be logged on. This password
should be changed for the future system security. If you forgot the password, you should receive
the technical support of the company.
If the log on is successful, the main menu is displayed on the screen. After this, set up ATM PVC
by using the functions provided from the main menu and then, if necessary, set up the IP address
of RECSPEED-8000E, the subnet mask, and the IP address of basic gateway.

5.4.2 Main Menu – ATM Interface – Create ATM PVC
This menu is used to set the ATM PVC. Up to four ATM PVCs can be set. One ATM PVC
operates as one bridge port. At this time, such parameters as the port number of the
corresponding PVC, VPI/VCI value and PCR value must be specified.
Values available for these parameters: 2 – 5 for port number, 0 – 255 for VPI value, 0 – 65535 for
VCI value, and 0 – 1000 for PCR value.
However, if the VPI value is set as 0, the VCI value is 32-65535. This is because VPI of 0/0- 0/31
and VCI values are defined in advance by the related standards for the special use.
In addition, the PCR value should not exceed 1000 by summing up the PCR values that are set in
up to four set ATM VCCs. For example, if the PCR values of port number 2, 3, and 4 are 200,
300, and 300 respectively, the PCR value of port number 5 available for the ATM VCC setup
should not exceed 200.
The following screen is displayed.

If you do not know the port number to be deleted, first display the current PVC setup status and
then, enter the port number.
The port number ranges from 2 to 5.
The following example shows that the ATM VCC assigned for port number 2 is deleted.

The example above shows that the current setup mode is “G. Lite” and that to change the mode
into “Full Rate”, “F” is entered. Since this setup mode is stored even though the system power is
blocked, it is not necessary to reset the mode after setting it once.
