RECSPEED-8050E ADSL Ethernet Bridge Modem Installation Guide January of 2001 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.
! Connect the equipment into an outlet on a circuit different from that to Increase the separation between the equipment and receiver. 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 users authority to operate the equipment. CHAPTER 1.

Definition 1. What is ADSL?
ADSL (asymmetric digital subscriber line) is called "asymmetric"
because most of its two-way or duplex bandwidth is devoted to the downstream direction, sending data to the user. Only a small portion of bandwidth is available for upstream or user-interaction messages. Using ADSL, up to 6.1 Mbps of data can be sent downstream and up to 640 Kbps upstream. 2. ADSL Features.
" High Speed Access
" Always On Connection
" Voice and Internet At The Same Time
" Security
( Figure1. ADSL Service Process ) CHAPTER 2. Preliminary Application Notes 1. Power Adaptor The RECSPEED-8050E using 9V/1A DC power adaptor. And inside of the plug is positive polarity and outside of the plug is negative polarity. If you didnt get a power adaptor with the modem, please find a power adaptor meet above spec. 4 2. LED definition The RECSPEED-8050E, ADSL Bridge/Router has five status LEDs for diagnostics. You can monitor the LEDs during operation. Following table shows RECSPEED-8050E ADSL Bridge/Router status LEDs and identifies what each LED light means. There are 5 LEDs in front panel of ADSL modem. PWR ADSL PC RX TX Dark for power off Light for power on Flashing slowly for ADSL training in progress Light for the ADSL link is establish and ready to Transfer data Dark for no Ethernet link present of Power off Light for Ethernet link present Dark for no user data received through the Bridge/Router Flashing for user data received through the Bridge/Router Dark for no user data transmitted through the Bridge/Router Flashing for user data transmitted through the Bridge/Router 3. Real Panel The rear panel of RECSPEED-8050E ADSL Bridge/Router consist of power jack, Console Port connector, Ethernet connect and ADSL like jack as shown below:
DC 9V Console 10Base-T ADSL 4. Right side of cabinet The power switch is located in the right side of RECSPEED-8050E as shown below:
0 1 5. Serial Console Port Setup The ADSL modem support a console port for setup the configuration of ADSL modem. You can use any terminal software to communicate 5 the ADSL modem with following parameter :
6. TELNET Console Port Setup The ADSL modem also allows be configured through the TELNET session. The default IP of the Ethernet port in ADSL modem is pre-
configured to 192.168.7.1. And it required a password to login the TELNET session. The default password is EA-700 and case sensitive. 7.
