American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 May 16, 2006 RE: FCC ID: AB6NT3030VBTS_ATCB003465 Attention: Thomas Wong I have a few comments on this Application. Please note that further comments may arise in response to answers provided to the questions below. 1. FYI - Please note that the FCC has in the last 12 months had objections to listing emissions designators for 2M25F9W, 3M73F9W etc. The positions is basically that these transmissions are only adjacent channels used in conjunction and as such would fall under the 1M25 designation. Please be aware that should the FCC require, these designators may have to be removed from the grant. 2. Please note that the test report does not clearly identify the test methods used for spurious ERP measurements. Please note that TIA603 is the required method. While the results appear to be for this method, no statement to that affect has been made. Please explain if TIA603 was used, or if another method was used to make these measurements. 3. Please note that confidentiality has been requested for the internal photos. Howver, please also note that the manual has not been requested to be confidential and it contains photos and drawings of the internal mechanisms of the base station. If this information is considered confidential, you will also need to put the manual under the confidentiality request. Please advise.

Introduction This test report is submitted in accordance with the FCC Rules and Regulations, Part 2, Subpart J, Sections 2.1046 through 2.1057 for equipment authorization of Nortel Networks’ CDMA 800 MHz Village Basestation 3030 Radio Module (vBTS 3030 RM). The 800 MHz vBTS 13030 RM is intended for use in the Domestic Public Cellular Radio Telecommunications Service and is designed in accordance with the following standards: • CFR 47, Part 22, Subpart H, Subpart H, Cellular Radiotelephone Service[1] • CFR 47, Part 2, Subpart J, Equipment Authorization Procedures - Equipment Authorization[2] 2. Test Result Summary Table 1 summarizes the measurement results for the CDMA 800 MHz vBTS 3030 RM. Table 1: Test Results Summary FCC Measurement Specification FCC Limit Specification Description Results Test(s) Conducted by Remarks 2.1033(c)(8) Measurement of DC Power Provided 2.1046 RF Output Power Provided Nortel Networks See Exhibit 2A 2.1047 Modulation Characteristics Not Applicable 2.1049 Occupied Bandwidth Provided Nortel Networks See Exhibit 2A 2.1051, 2.1057 22.917 Spurious Emission at Antenna Terminals Compliant Nortel Networks See Exhibit 2A 2.1053, 2.1057 22.917 Field Strength of Spurious Radiation Compliant NTS Calgary See Exhibit 2B 2.1055 22.355 Frequency Stability Compliant Nortel Networks See Exhibit 2A 4 2. Engineering Declaration The CDMA 800 MHz vBTS 3030 RM has been tested in accordance with the requirements contained in the Federal Communication Rules and Regulations Part 2 and 22.
