FCC ID : RZEDV-201DM 2.1 INTRODUCTION The measurement procedure described in American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9kHz to 40GHz (ANSIC63.4-2001) was used in determining radiated and conducted emissions emanating from DAVOLINK INC. VoIP Gateway FCC ID: RZEDV-201DM The open area test site and conducted measurement facility used to collect the radiateddata are located at the 254-1, MAEKOK-RI,HOBUP-MYUN,ICHON-SI,KYOUNGKI-DO, 467-701,KOREA. The site is constructed in conformance with the requirements of ANSI C63.4and CISPR Publication 22. Detailed description of test facility was submitted to the Commissionand accepted dated July 23,2003 (Confirmation Number: EA90661) REPORT NO. : HCT-F04-1314 HYUNDAI C–TECH 4/18

FCC ID : RZEDV-201DM 3.1 PRODUCT INFORMATION 3.2 Equipment Description Equipment Under Test (EUT) is DAVOLINK Inc. ( Model : DV-201DM ) VoIP Gateway FCC ID: RZEDV-201DM Power: External Adaptor (Input:110~220VAC/Output:VDC) Input Power source : AC 110~240V (50/60Hz) Voltage Fluctuation Range : ±10% Dimensions: 189mm(W) x 173mm(H) x 38mm(D) Connectivity: DC IN, LAN, TEL, LINE Weight (Net):1.5Kg REPORT NO. : HCT-F04-1314 HYUNDAI C–TECH 5/18

FCC ID : RZEDV-201DM 4.1 Description of Tests(Conducted & Radiated) 4.2 Powerline Conducted Emission (150kHz- 30MHz) The power line conducted RFI measurements were performed according to CISPR 22. The EUT was placed on a non-conducting 1.0 by 1.5 meter table which is 0.8 meters in height and 0.40 meters away from the vertical wall of the shielded enclosure. Power to the EUT is provided through a Rohde & Schwarz 50 Ω / 50 uH Line Impedance Stabilization Network (LISN) and the support equipment through a separate Solar 50 Ω / 50 uH Line- Conducted Test Facility LISN. Sufficient time for the EUT, support equipment, and test equipment were allowed in order for them to warm up to their normal operating condition. The RF output of the LISN was connected to the spectrum analyzer to determine the frequency producing the maximum EME. The spectrum was scanned from 150kHz to 30 MHz. Each maximum EME was measured using an EMI receiver. The detector function of the receiver was set to CISPR quasi- peak and average mode with the bandwidth set to 9 kHz. Each emission was maximized consistent with the typical applications by varying the configuration of the test sample. Interface cables were connected to the available interface ports of the test unit. The effect of varying the position of cables was investigated to find the configuration that produces maximum Diagram emission. Excess cable lengths were bundled at the centre with 30- 40cm. in length. The worst-case configuration is noted in the test report and the photographs are attached. Each EME reported was calibrated using the Rohde & Schwarz SMX signal generator and are listed on Table 1. RFI Conducted FCC Class B FCC CLASS B RFI CONDUCTED Limits dB(uV/m) CISPR 22 CISPR 22 Freq.

FCC CLASS B Conducted Emission Limits 4.3 Description of Tests(Radiated) Radiated Emissions Preliminary measurements were made indoors at 1 meter using broadband antennas, broadband amplifier, and spectrum analyzer to determine the frequency producing the maximum EME. Appropriate precaution was taken to ensure that all EME from the EUT were maximized and investigated. The spectrum was scanned from 30 to 300 MHz using biconical antenna, 300 to 1000 MHz using log- periodic antenna, and above 1 GHz using linearly polarized horn antennas. Final measurements were made outdoors at 10-meter test range using Dipole antennas and EMI receiver. For frequencies above 1 GHz, horn antennas were used. Sufficient time for the EUT, support equipment, and test equipment were allowed in order for them to warm up to their normal operating condition. The EMI receiver detector function was set to CISPR quasi-peak mode and the bandwidth of the receiver was set to 120 kHz. The EUT, support equipment, and interconnecting cables were arranged to the configuration that produces the maximum EME emission found during preliminary scan. The turntable containing the system was rotated; the antenna height was varied 1 to 4 meters and stopped at the azimuth or height producing the maximum emission. Horizontal and vertical antenna polarizations were checked. Each emission was maximized by: varying the mode of operation or resolution; clock or data exchange speed; scrolling H pattern to the EUT and/ or support equipment, and powering the monitor the computer aux AC outlet, if applicable; and changing the polarity of the antenna, whichever determined the worst-case emission.

FCC ID : RZEDV-201DM 10.1 Test Software Used The EUT exercise program used during radiated and conducted testing was designed to exercise the various system components in a manner similar to a typical use. The software, contained on a 3-1/2 inch disc, was inserted into drive A and is auto starting on power-up. Once loaded, the program sequentially exercises each system component in turn. The sequence used is :(1) Display test, (2) RS 232 test (3) Key board test,(4) Printer test,(5) FDD test,(6) HDD test. The complete cycle takes about 20 seconds and is repeated continuously. As the keyboard and mouse are strictly input devices, no data is transmitted to them during test. They are however, continuously scanned for data input activity. The video resolution modes setup and change program was used during the radiated and conducted emission testing. NOTE: This is a sample of the basic program used during the test. However, during testing, a different software program may be used; whichever determines the worst-case condition. In addition, the program used also depends on the number and type of devices being tested. Actual program used is the Display “ H “ Pattern , White Pattern , 100/0/75/0 Colour bars,1000 Hz Audio signal. All resolution modes were investigated and tested REPORT NO. : HCT-F04-1314 HYUNDAI C–TECH 18/18

FCC ID : RZEDV-201DM 11.1 Conclusion The data collected shows that the DAVOLINK INC. VoIP Gateway FCC ID: RZEDV-201DM. complies with §15.107 and §15.109 of the FCC Rules. REPORT NO. : HCT-F04-1314 HYUNDAI C–TECH 19/18
