The VIM board provides unregulated 12 Vdc power to the ITCU; in turn the ITCU supplies regulated 5 Vdc to the VIM board. The CCU is a component of the Car Control Device (CCD), which comprises, in addition to the CCU, the antennas and an on-car power generation and storage subsystem. The CCD, including the CCU, is installed on a railcar by either trained GE-Harris personnel, or by trained and experienced support personnel provided by the customer. This equipment is not offered for sale to the general public, and is only offered to commercial markets along with agreements that provide assurances that the equipment will be installed and utilized in accordance with all government and industry regulations and guidelines. In addition to the FCC, such agencies include, for example, …

Exhibit D Frequency Stability Data: Variation of Ambient Temperature Document No. 5001366 16 April 1999 GE Harris Railway Electronics, L.L.C. D.1 Introduction The frequency stability of the ITCU was measured with variation of the ambient temperature. The following data supports FCC requirements outlined in Section 2.995. D.2 Equipment • Sorensen LT 30-3 DC Power Supply (Set at 12.0 V, 0.6 A) • Thermotron Temperature Chamber • Fluke Multimeter with Thermocouple Module (taped directly to ITCU) • HP Spectrum Analyzer 8563 E • Maintenance Monitor with special test mode software D.3 Overview Testing for temperature stability took place at GE Harris under the supervision of Michael Lipsky. In compliance with FCC code 2.995,(a),1, ambient temperature was varied from –40 C to +70 C. In compliance with FCC code 2.995,(b), measurements were made at intervals of 10 C, while allowing a sufficient period of time (30 min.) to stabilize all of the components. For this test, the radio was placed in a test mode that causes it to generate two non-spread tones at f c ± 5.5 MHz. The actual center frequency is derived by calculating the centerpoint between the frequencies of these tones. This center frequency was determined for ambient temperatures from -40°C to +70°C, the operating temperature range of the device. The test data and a plot of frequency deviation vs. ITCU temperature is provided below. Document No. 5001366 16 April 1999 GE Harris Railway Electronics, L.L.C.

E.1 Introduction The frequency stability of the LCM was measured with variation of the primary power supply voltage. The following data supports FCC requirements outlined in Section 2.995. E.2 Equipment • Sorensen LT 75V DC Power Supply • HP Spectrum Analyzer 8563 E • Maintenance Monitor with special test mode software E.3 Overview Testing for power supply stability took place at GE Harris under the supervision of Michael Lipsky. In compliance with FCC code 2.995,(d),1, the voltage supply was varied from 85 to 115 percent of the nominal value (12 V). In compliance with FCC code 2.995,(d),3, measurements were made at the input to the cable normally provided with the equipment. For this test, the radio was placed in a test mode that causes it to generate two non-spread tones at f c ± 5.5 MHz. The actual center frequency is derived by calculating the centerpoint between the frequencies of these tones. This center frequency was determined for ambient temperatures from -40°C to +70°C, the operating temperature range of the device.

Exhibit F Processing Gain Test Data Prepared By: Harris Semiconductor 2 2401 Palm Bay Rd, N.E., M/S 62A-024 Palm Bay, FL 32905 Report of Measurements: Processing Gain GE-Harris Railway Electronics Intra-Train Communications Unit Scope: To assess performance of the GE-Harris Railway Electronics Intra-Train Communications Unit (ITCU), part number 1002244, S/N 303 for compliance with Processing Gain per FCC Part 15.247(e)(2) Test Setup and Procedure A block diagram of the test setup is shown in Figure 1 below. The setup was identical to that described in a paper presented at the 7 th Annual Wireless Symposium/Portable by Design Conference (1) and the setup was calibrated per procedures described in that paper. A standard Harris Semiconductor PCMCIA WLAN assembly, S/N 95VBB002394 was used as the DS transmitter. The system operates at a data rate of 1 Mb. The span of measurement was chosen to be 17 MHz, that being the 3 dB bandwidth of the IF SAW filter used in the system. Initially, therefore, the frequency of the Jammer signal was set 8.5 MHz below the center frequency of the DS spectrum. The signal strength of the Jammer signal was automatically adjusted by the ATE system in 0.1 dB steps until the Bit Error Rate (BER), averaged over 10,000 blocks of data, increased to be within a window centered at 1 x 10 -5 (1E-5), that being the standard BER as stipulated in IEEE802.11. The Jammer/Signal ratio was then logged, the frequency was increased by 50 kHz, and the procedure was repeated. In all, a frequency span of +/- 8.5 MHz around the DS spectrum’s center frequency was covered. The Processing Gain (PG) is related to the Jammer/Signal ratio (J/S) by the following equation: PG (dB) = E s /N o + J/S + L system where: PG = Processing Gain (dB) E s /N o = Reference Symbol/Noise Power ratio (dB) needed to produce the standard BER of 1E-5 J/S = Jammer/Signal ratio (dB) L system = System Implementation Loss (dB) In our case of 1 Mb BPSK IEEE802.11 compliant modulation, E s /N o = 10.3 dB. Although it can be shown that the actual System Implementation Loss exceeds 2 dB in our system, L system is imputed by the FCC to be 2 dB maximum and this figure is therefore factored into the equation. The equation used to compute Processing Gain therefore becomes: PG (dB) = 10.3 + J/S + 2 = 12.3 + J/S (dB) (1) Abrahams, Richard L., “Measurement of Processing Gain in a Direct Sequence WLAN Using the CW Jammer Method”, Proceedings of the 7 th Annual Wireless Symposium/Portable by Design Conference, San Jose CA, 2/22 through 2/26/99. GE-Harris ITCU Processing Gain 3 RESULTS: Processing Gain was measured on three separate channels: CH6, 2437 MHz (in the approximate center of the ISM band) CH1, 2412 MHz (at the low end of the ISM band) CH11, 2462 MHz (at the high end of the ISM band) Per 15.247(e)(2), the Processing Gain was taken at the 20 th percentile point of the logged data. Detailed data is presented in Appendices A through C.
