August 2, 2000 Federal Communications Commission Authorization & Evaluation Division 7435 Oakland Mills Road Columbia, Maryland 21406 Attention:Equipment Authorization Branch Subject:Certification for FCC ID: AXATR-415-A2 Gentlemen, Ericsson Inc. requests certification (type acceptance) for the AXATR-415-A2. This OEM module transceiver is designed as a mobile for use in the AMPS/DAMPS cellular telephone system operating in the 800 MHz Domestic Public Cellular Radiotelephone Communications Services per Subpart H of part 22. This OEM module meets the requirements of IS-137A for operation in cellular systems. This OEM module is similar to previously type accepted FCC ID: AXATR-400-A2. Ericsson requests an exclusion from routine RF exposure measurements based on the discussion presented in Exhibit 11, RF Exposure Evaluation, since the analysis of the maximum RF exposures under worst-case and typical conditions clearly demonstrates compliance with the amended FCC rules. We have included specific instructions and warnings in Exhibit 8, OEM Interface Manual, regarding minimum separation distance, maximum antenna gain, and that use as a portable transmitter will require separate FCC approval for SAR compliance. Ericsson Inc. requests confidentiality under 47 CFR 0.459 for the following exhibits listed: Exhibit 4Block Diagram Exhibit 5Schematic Diagrams Justification of this request is that in order to facilitate the circuit miniaturization of the AXATR-415-A2, proprietary techniques were implemented in the transmitter, receiver, and baseband circuitry. To protect Ericsson’s competitive advantage on these proprietary techniques, we request the above listed exhibits be held as confidential and withheld from the Public Information File. Sincerely, Jim Sponsler Staff Engineer, Regulatory ServicesTel No:(919) 472-6460 Research Triangle Park, NCFax No:(919) 472-7452 August 2, 2000 Federal Communications Commission Equipment Approval Services PO Box 358315 Pittsburgh, PA 15251-5315 Subject:Enclosed a check for Type Acceptance and Confidentiality follows: FCC IDFEE AXATR-415-A2$ 580.00 Sincerely, John Rothgeb Specialist Regulatory Programs Room 2669 Tel:(804) 592-7476 Fax:(804) 592-6510 Enclosures:Check Filing for Equipment Approval Branch

To:Frank Coperich [email protected] FCC Application Processing Branch From:Jim Sponsler, Ericsson Inc Re:FCC ID AXATR-415-A2 Applicant:Ericsson Inc Correspondence Reference Number:15904 731 Confirmation Number:EA98413 Date of Original E-Mail:09/05/2000 Ericsson, EA 98413 - 1. Filing has made a request for exclusion from routine MPE evaluation and also indicate that the current device is similar to a previously approved device (AXATR-400-A2, EA 94593). The current device is requesting for a maximum output of 355 mW for all operating modes, therefore, all modes should be categorically excluded from routine MPE if all outputs are less than 1.5 W ERP. The previous device had 3.0 W peak output for one of its modes, which was not categorically excluded from routine MPE evaluation and had requested for an exclusion. Please clarify the maximum output of all operating modes for the current device and its association with the previous device (has same model number, DM-10) described in the cover letter. The previously approved device (AXATR-400-A2) was renamed from a DM10 to a DM10A, with the “A” suffix indicating the presence of 3.0 W peak output burst mode amplifier circuitry. The current device being certified is known as the DM10, and it does not include the burst mode circuitry, and is limited in output power to 355 mW for all operating modes. 2. Exhibit 6G1 (Ericsson labeled) describes a DM-20 module, please clarify which modules are included in this filing. The reference to the DM20 is a typo, it should have read DM10. The amended (corrected) document is attached, Exhibit 6G Rev B. 3. Please modify proposed "Safety" Section of the manual to indicate in Section 3.1 that this OEM module is designed and must be configured to operate with respect to Section 2.1091 of FCC rules, as a mobile transmitting device for satisfying RF exposure compliance requirements. It is not intended for use in hand-held or portable transmitting devices, which are required to obtain separate FCC approval to satisfy SAR compliance with respect to 2.1093 of FCC rules. OEM integrators are cautioned to follow these requirements. Exhibit 8 has been modified to reflect the recommended changes, and is attached, Exhibit 8 Rev B. 4. FYI - RF exposure info (section 1.2) describes device has 355 mW ERP, which should be conducted output. Section 2.3 describes a 30 minute averaging time, which is only applicable to fixed-mounted transmitters. Mobile and portable transmitters are required to satisfy source-based time-averaging requirements; please review rules in 2.1091 and 2.1093. MPE limits are more restrictive at the low end of the frequency band, MPE should be estimated with limits at the lowest operating frequency for the device to ensure compliance. Exhibit 11 has been corrected, and is attached, Exhibit 11 Rev B. 5.) Please submit a showing of compliance with the E-911 requirements under Section 22.921 Exhibit 2 has been amended to address E-911, and is attached, Exhibit 2 Rev B. The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information within 60 days of the original e-mail date may result in application dismissal pursuant to Section 2.917 (c) and forfeiture of the filing fee pursuant to section 1.1108.

CIRCUIT & DEVICE DESCRIPTIONS PARA. 2.1033 (b)(4), (c)(10) (10)FREQUENCY STABILIZATION A temperature compensated crystal oscillator (N1402) provides a 19.44 MHz reference frequency signal for the transmitter and receiver frequency synthesizers. This reference frequency is internally compensated to be within ±2.5 ppm over the temperature range of -30°C to +75° C. Upon power-up, the receiver searches and acquires a base station signal, and it adjusts the reference oscillator frequency to align itself to the high accuracy time base of the base station. The transmitter does not engage until after the receiver synchronizes to the base station. (11a)ATTENUATION OF SPURIOUS EMISSIONS The 800 MHz band transmitter frequency is obtained from mixing a phase locked VCO operating from 979.53 MHz to 1004.49 MHz with a 155.52 MHz signal. The 155.52 MHz signal is obtained by phase locking an oscillator to the VCTCXO output. The 800 MHz band receiver frequency is obtained by dual conversion. The first conversion is obtained by mixing the incoming signal with the 979.53 MHz to 1004.49 MHz VCO to a first IF frequency of 110.52 MHz. The second conversion mixes the IF frequency with a phase locked VCO at 110.4 MHz to obtain the second IF frequency of 120 kHz. All VCO’s are phase locked to the reference VCTCXO. As a result of the above circuitry, the spurious signals are transmitter harmonics, reference oscillator 19.44 MHz harmonics, the local oscillators and the microprocessor clock. The use of multi-layer printed circuit boards, with signal tracks between ground planes, for the radio as well as for the logic areas reduces the radiation to a minimum. Ceramic resonator bandpass filters for the duplexer attenuate conducted transmitter harmonics, reference oscillator and local oscillator signals. A bandpass filter in the receiver front end attenuates the local oscillator signal further. Additional suppression of radiation is achieved by shielding and key isolation between circuits. (11b)LIMITING MODULATION The modulation for the transmitter is produced inside a Digital Signal Processing integrated circuit. The modulation limiting is therefore controlled by an algorithm inside this chip. The limit is preset at the factory and cannot be changed thereafter. ATTENUATING HIGHER AUDIO FREQUENCIES The DSP chip provides an audio filter with a 120 log (f/3000) response, f=3K to 20KHz. Manchester encoded data signals are filtered prior to transmission by a four-pole lowpass filter providing an attenuation of 24 dB/Octave above 20 kHz. The signal produced by the DSP chip is a differentially shifted PI/4 QPSK signal for the digital system and a FM signal for the analog cellular system. These signals are fed through a three-pole lowpass filter with a 3 dB down cut-off frequency of 25 kHz to limit the adjacent channel energy in the digital mode. APPLICANT: ERICSSON INCFCC ID NO: AXATR-415-A2 Exhibit 12APage 2 of 3 ©2000 Ericsson Inc. CIRCUIT & DEVICE DESCRIPTIONS PARA. 2.1033 (b)(4) (11c)OUTPUT POWER CONTROL A loop circuit under supervision of the logic sets the output to any of the eleven power levels. A digital word is transmitted to the gain control amplifier for output power adjustment. A detector at the output of the power amplifier module senses the RF energy present and sends a corresponding DC voltage to the digital logic circuitry. Upon receiving a command to set power level from the handset or from a base station the microprocessor sends a predetermined word to the ALC amplifier. The output detector voltage is then read by the microprocessor and compared to a preset value. If the detector voltage is outside the allowed tolerance an adjustment is made to the gain-controlled amplifier to bring the detector voltage into the proper range. (12)DIGITAL MODULATION TECHNIQUES The NRZ data stream is transformed to 10kbps Manchester encoded data in such a way that each NRZ binary one is transformed to a zero-to-one transition, and each NRZ binary zero is transformed to a one-to-zero transition. The Manchester encoded data stream is filtered before being applied to the modulator. Direct binary frequency shift keying is used. A binary one into the modulator corresponds to a normal peak frequency deviation of 8kHz above the carrier frequency and a zero corresponds to a nominal peak frequency deviation 8 kHz below the carrier frequency. (12a)DESCRIPTION OF PI/4 DQPSK The modulation method used for the digital mode is known as PI/4 shifted differentially encoded Quadrature Phase Shift Keying. Eight distinct phase states are possible. The signal information is differentially encoded; symbols are transmitted as changes in phase rather than absolute phases. Transition of phase which would result in a zero amplitude momentarily are not allowed. APPLICANT: ERICSSON INCFCC ID NO: AXATR-415-A2 Exhibit 12APage 3 of 3 ©2000 Ericsson Inc. CIRCUIT & DEVICE DESCRIPTIONS PARA. 2.1033 (b)(4) 1.0 LOGIC BOARD OPERATION The logic board is the central controller system for the radio. It is made up of a microprocessor, DSP, codec, memory, and control logic. 1.1 ASIC CONTROL CHIP – D401 The ASIC control chip is made up of a ARM microprocessor and application specific logic circuits. The chip is the main control center for the radio and provides interfaces to the DSP’s, codec, memories, keypad, display, alarms, and system interfaces. 1.2 MEMORY CHIP’S D501 is the 1M x 8 flash memory used to store the radio’s operating algorithm. This part may be field programmed to allow new revisions of the operating algorithm to be installed without opening the radio case.

FCC ID NO: AXATR-415-A2 Exhibit 10B ALIGNMENT PROCEDURE Page 1 of 4 ©2000 Ericsson Inc. PARA. 2.1033 (c)(9) Due to the high accuracy of the I/O, the modulation, transmit voice, DTMF, SAT and data deviations are all preset in the DSP software and are not adjustable in production or the field. These procedures give the test method to verify the phone has proper deviations. RADIO TUNE/TEST INSTRUCTIONS FILTERING SAW, ceramic, and crystal filter technologies are used, and no tuning is required. REFERENCE FREQUENCY ADJUSTMENT TEST SETUP Testing of the VCTCXO circuit is temperature dependent and should be carried out at an ambient room temperature of +23°C to +27°C. Any frequency adjustments should be made 1.0 hour after re-flow soldering to allow for relaxation of thermal stress. Terminate ANT (X1802) into a frequency counter with a 50Ω input impedance. Enter the following test commands: **** The same channel should be used for all parts of this test **** @2705 (read thermistor A/D from Patti) check result 1 @80 (initialize the transceiver- carrier off and audio muted) @6502 (AFC off) @E11401FF (center DAC3) @3Czzxxxx (select a MID-CHANNEL) @8407 (set the transmitter power level 7) @81 (turn the transmitter on) check result 2 TEST RESULTS 1. Verify that the returned value is in the range 41 to 54 hex. (A higher temperature corresponds to a lower reading). 2. Wait until output is stable (<±42Hz variation in frequency).
