FCC ID:OB5WPBX-9000-H Date: August, 1999 Project number:13308 Page 1 of 5 OPERATIONAL DESCRIPTION FCC ID:OB5WPBX-9000-H Date: August, 1999 Project number:13308 Page 2 of 5 SYSTEM DESCRIPTION The wireless PBX uses a spread spectrum frequency hopping RF link to transfer control data and digital compressed voice at a bit rate of approximately 115Kbit/sec in each direction. PBX features such as digital voice data switching, CO lines interface control and extension controls are all done at the base module. System basic configuration is done from the handsets. The Base unit manages the Handsets (Data and control). It acts as two CO lines interface and perform all PBX function. Other system options are two additional CO lines interface and TAD. The system consists of two major subsystems: 1. Base with upgrade capabilities, which optionally includes two extra CO lines and TAD in all combinations. 2. Wireless handsets (up to fifteen, eight of which can be operate simultaneously). The communication method between the wireless handsets and the Base complies with the WINGs TM standard. Following, a short description of the handset block diagram: • RF Module – Based on the Butterfly’s MMIC BFM9011J and BFM 9021J for 900MHz SSFH The RF module interfaces the handset through the BFC2203 (include controls and programming). The RF module has it’s own voltage regulator. • Base band – BFC2203 ASIC implementing of WINGS TM protocol. It communicates with handset controller using SPI protocol (with chip select option). The BFC2203 runs at 12MHz using a 12MHz crystal with 5ppm accuracy. • BFA5220TQ – HS application controller used to communicate with the WINGS TM network, operate the DSP, LCD and keypad, monitor battery discharging, supervise battery charging and implement the higher level protocol with the Base unit. • DSP – CT8015 TrueSpeech ® DSPG VOCODER. • CODEC and Audio Amplifier – Minus 3 volts PCM CODEC integrating the audio circuitry for microphone and earphone. The microphone is an omnidirectional condenser of the type WM- 54B. The earphone is 150Ω dynamic receiver for telephone HS. • LCD – A 2 lines of 12 characters dot matrix each, and 12 icons. Controlled by PHILIPS PCF2113x controller. Communication with HS controller is done over I 2 C protocol. • Keypad – Handset’s keypad is 19 printed switches, mapped on a 7X3 matrix. Matrix coulombs are connected to the lower bits of HS controller data bus, and matrix rows are connected to the interrupt lines of HS controller. The HS operates from three AAA cells NiMH 550mAh rechargeable battery. Voltage operation range is from 3.0 volts, and up to 4.3 volts. Two low-drop 3 volts regulators are used to maintain a constant voltage to all modules. One for the RF module with operation control ability (some parts of the RF transmitter operate directly from the battery). Second regulator (operates continuously) is used for all other components (excluding RF module). Voice channel components (DSP, CODEC and microphone) are powered through power switch controlled by HS application. FCC ID:OB5WPBX-9000-H Date: August, 1999 Project number:13308 Page 3 of 5 General The transmitter and receiver in the RF module share a single antenna terminal which is switched between them on a TDD basis (time division duplex), i.e., when a data packet is received the transmitter is inactive and does not interfere with the reception, and the reception is inactive during transmissions. The transceiver employs frequency hopping spread spectrum which is managed by the baseband processor (external to the RF module). The transmission and reception are based on synthesized oscillators that share the same 12 MHz reference clock which is provided as an input to the module. • Carrier Frequencies The transceiver’s 50 frequencies are: 902.5MHz, 903.0MHz, 903.5MHz...927.0MHz (902.5MHz to 927.0MHz with 0.5MHz channel separation). • Modulation and Bandwidth The modulation index of the FSK modulation is set to h≅0.5, which creates a modulated signal with a 20dB bandwidth of about 500kHz (maximum allowed by the FCC in this frequency band). Receiver The receiver is a dual conversion heterodyne receiver with a second IF at 10.7 MHz, where the FSK demodulation is performed. Its circuitry is based on the BFM9021J incorporating a low-noise- amplifier, two frequency conversions, an FM demodulator and an RSSI output (received signal strength indication). An external baseband stage functions as a data slicer and provides a logic- level output which is interfaced with the digital logic external to the module. The first conversion is based on a synthesized local oscillator which is set at 110.7 MHz above the received frequency (the first IF is at 110.7MHz). The second conversion is based on a fixed crystal oscillator at 100MHz which down-converts the modulated signal to the second IF of 10.7MHz. The receiver sensitivity for a bit error rate (BER) of 10 -5 is about –93dBm. Transmitter The transmitter is based on the BFM9011 IC, which incorporates the modulator and the power amplifier. The transmission power may be adjusted externally between a few power levels reaching a maximum of about 20 dBm (100mW). The RF oscillator runs at the carrier frequency and is frequency modulated directly by the data signal while the synthesizer loop is disabled.

ABEST COMMUNCATION CORP. 19-7 Ting-Tien-Liao, Hsien-Jenli, Tel: 886-2-26237902 2623-7903 Tamsui, Taipei, Taiwan, R.O.C. Fax: 886-2-2621-7261 October 10, 1999 Response to FCC’s Inquiry Regarding Selection of Frequencies in the Hopping Sequences (ABEST’s WPBX-9000 WiNGs TM Based Wireless PBX) 1. Adaptiveness of Hopping Sequences At system initialization, before the system’s base and handsets start transmitting, the base unit selects 5 frequency segments (“slices”) from the available 10 (see Table 1 in the attached appendix). These slices are selected using a minimal interference criterion based on measurements of received levels of interference performed throughout the initialization period. Once this selection has been made, the order of frequencies is set according to a randomization & scrambling algorithm. The various transmitters in the system transmit at different time slots (TDMA), and hence never occupy two frequencies simultaneously, or collide with each other. Collisions with other systems in the environment are possible, since the frequency use of each systems is not coordinated with that of others. The hopping sequences for each device are dynamically and independently modified further according to packet reception failures throughout their use. The system holds a separate error counter for each frequency slice (shared amongst 5 frequencies), and once this counter exceeds a predefined parameter, the frequency slice is considered inappropriate, and is replaced with a spare one that hasn’t been in use at that time. This complies with the FCC rules (15.247h), allowing the intelligent selection of frequencies based on reception indications, since the system does not coordinate its frequency use with that of other systems by any means. 2. Contents and Randomness of Hopping Sequences The frequency hopping sequences in the WPBX-9000 are based on a periodic use of 25 frequencies, which is the minimal number of frequencies required for systems transmitting up to 0.25W (the transmission power in the WPBX-9000 is 100mW). The order of appearance of the selected frequencies is randomized and scrambled by means of software to obtain a pseudo-random pattern. The calculation of the scrambling parameter used as a randomization seed, is based on the following: the RSSI levels corresponding to the reception of noise/interference, the system’s unique 6-byte identification number, and a random value determined by the system’s clock. This ensures both the random nature of the hopping sequence and its orthogonality with other sequences generated similarly in other neighboring systems. During the operation of the system, each of the handsets which communicates with the base has an individual frequency hopping link with the base, with multiplexing performed on the time axis (TDMA). Each of these separate channels is monitored and dynamically changed according to the link failures encountered in it. Consequently, the system may end up using different frequency sequences for the various handsets in it, depending on the link conditions of each of them. The 25 frequencies selected for a specific transmitter at a certain time will always comprise 5 frequency slices, each containing 5 different channels. Table 1 in the attached appendix lists all 50 available hopping channels, as they are arranged in frequency slices. Apart from frequency slice #9, which contains frequencies at which the system’s reception sensitivity is slightly degraded, the frequency slices are arranged in their order of appearance on the frequency axis. Table 2 describes a typical pseudo-random sample sequence generated by the system.
