SL-4560 ADSL Modem 1 ADSL External Modem (SL-4560) SL-4560 ADSL Modem 2 FCC NOTE :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 measures: -- Reorient or relocate 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. THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER'S AUTHORITY TO OPERATE THE EQUIPMENT. SL-4560 ADSL Modem 3 Table of contents 1.

Introduction of SL-4560 ADSL Modem SL-4560 ADSL Modem 5 1.1 Introduction of ADSL ADSL means ‘Asymmetric Digital Subscriber Line’. Using word of ‘Asymmetric’, because there are difference between upstream speed and down stream speed. As you could see in the diagram below, downstream use more wide bandwidth than upstream. Technology that allows more data to be sent over existing copper telephone lines (POTS). ADSL supports data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate). ADSL requires a special ADSL modem. ADSL is growing in popularity as more areas around the world gain access. <Picture 1-1> ADSL Service Diagram SL-4560 ADSL Modem 6 1.2 SL-4560 ADSL Modem /Frontside z The Front of SL 4560 <Picture 1-2> the front of SL-4560 ADSL z LED Explanation.

The factors contributing to uncertainties are test receiver, Cable loss, antenna factor calibration, Antenna directivity, antenna factor variation with height, antenna phase center variation, antenna frequency interpolation, measurement distance variation, ite imperfection, mismatch, and system repeatability. Based on NIS 80,81, The measurement uncertainty level with a 95% confidence level were applied. sample calculation Conducted emission The field strength is calculated by adding the LISN factor, cable loss from the measured reading. The sample calculation is as follows: FS = MR + LF + CL MR = Meter Reading LF = LISN Factor CL = Cable Loss If MR is 30dB, LISN Factor 1dB, CL 1dB The result (MR) is 30 + 1 + 1 = 32dBuV E E M M C C T T E E S S T T R R E E P P O O R R T T Report reference No: KST-FCC0418 KOSTEC Co.,Ltd. 180-254,Annyung-Ri, Taean-Yup, Hwasung-shi, Kyunggi-do, Korea Tel : +82-31-222-4251 Fax: +82-31-222-4252 http://www.kosteclab.com Page : 7 of 17 June 3, 2004 5.
