SAU-1900E CIRCUIT DESCRIPTION & THEORY OF OPERATION Product Description: SAU-1900E Wireless Local Loop The function of the SAU-1900E is to provide a wire-free interface between a Telephone Service Provider and the telephone wiring in a home or business. Up to 4 Telephones (or equivalent telephone-like loads) may be connected through up to 1000 Feet (~300 meters) of wire to the SAU-1900E to support a single-line (single phone number) telephone service. The SAU-1900E interfaces to the Public Switched Telephone Network (PSTN) via the 1900 MHz CDMA Cellular Phone Interface per IS-98A. The SAU-1900E provides all features associated with a standard ‘Plain Old Telephone System’ (POTS), plus Enhanced Features including the following: Telephone Battery Voltage (-60 to -68VDC), Telephone RINGING Voltages (40 Vrms minimum), Call Progress Signaling (Dial Tone, Stutter Tone, Receiver Off-Hook, Busy Signal, etc.) Caller-ID Signaling per GR-30-CORE, Call Waiting, Cancel Call Waiting, 3-Way Calling, Call Forwarding, and Cancel Call Forwarding. An optional expanded feature of the SAU-1900E is the ability to add an analog modem to the telephone line. This allows for the addition of an analog fax machine or a personal computer equipped with a modem. The following major functional blocks accomplish these features of the SAU-1900E: a. Subscriber Loop Interface Circuit b. 12V Battery Management c. Caller-ID FSK Generator d. Interface Circuitry e. DC/DC Power Supply f. CDMA RF and Baseband Interface f.1. Receiver f.2. Transmitter f.3. Synthesizer f.4. Baseband ASIC f.5. Mobile Station Modem g. MDL-1 Fax/Data (Optional) SAU-1900E CIRCUIT DESCRIPTION & THEORY OF OPERATION SUBSCRIBER LOOP INTERFACE CIRCUIT (SLIC): The Subscriber Loop Interface Circuit (SLIC) provides the means to transfer the voice-band audio signals between the CDMA board and the Telephone line. It also uses the output of the DC Power supply to provide telephone line power and power for ringing telephone extensions. All of these functions are accomplished via a single IC (U501) with external components selected to establish the desired operating parameters. A more detailed description follows: Operating Modes: The SAU controller (located on the CDMA board) establishes the following operating modes by setting the GPIO (and/or GPIO_Expansion) lines to an appropriate state. 1. Low Power Scan: In this state, the SAU controller configures the DC/DC converter to supply a – 65VDC to the Battery Input pins of U501. All other internal circuits, except for the off-hook detector, are turned off to conserve power. The SAU will be placed in this state when U501 indicates that all attached telephone-like loads are in an On-Hook (high DC impedance) condition. 2. Powerup, Forward: This is the normal condition when at least one phone is Off-Hook and a conversation is either in-progress or in the process of being established. The DC/DC power supply is configured for -24 Vdc (rather than -65 Vdc) to conserve power (for increased talk-time on battery power) and to reduce heat dissipation in U501. While in this mode, the SLIC acts as a DC Current Source to provide a 30 mA loop current for powering the telephone. In this state the SLIC IC converts AC Loop Current Signals from a telephone into AC Voltage Signals for transmission to the CDMA CODEC. In addition it operates as a signal amplifier for transmitting voice band analog signals received from the CDMA CODEC to the low impedance telephone receiver. 3. Powerup, Reverse: Same as the state listed above, except the Tip and Ring voltage polarities are reversed from normal {normally Tip is more positive than the Ring line}. This state is infrequently used, typically for signaling equipment other than telephones, which may also be attached to a telephone line. Normal telephone operation is unaffected by Tip/Ring polarity. 4. Ring State: When configured for this mode, and with the DC/DC power supply configured to provide -65 Vdc, the SLIC can apply a 20 Hz, 40-55 Vrms Ring signal to alert a telephone user of an in-coming call. In addition, U501 will monitor the ring current to determine when the phone is taken off-hook so that the SAU controller can terminate the ring signal and the Powerup Forward state can be established. Contrary to standard wireline ringing signals, wherein a Telephone Central Office supplies a 90 Vrms ringing signal which is superimposed upon a battery voltage of -48 Vdc, the SAU-1900E produces the ring signal by reversing the tip/ring voltage at a 20 Hz rate. Wave shape is controlled to produce a balanced trapezoidal waveform with a peak-to-peak swing of approximately 120 Vpp and a RMS voltage between 40 Vrms and 55 Vrms. This waveform is sufficient to ring all telephone types (including older phones with electromechanical ringers) under short loop length (< 100 meters) applications. In addition, up to 4 Ringer Equivalent Network (REN) loads may be simultaneously attached while still providing the minimum 40 Vrms ringing signal. 5. Disconnect State: During this mode of operation, the SLIC is put into a low power mode and the Tip/Ring lines put into a high impedance condition (> 100K Ohms). This state is applied for approximately 800 mSec after receipt of a far-end disconnect message to signal telephone answering machines (and other, similar equipment) to stop recording and to go into an On-Hook condition. Satisfactory audio performance relies upon the ability of this circuit to provide an electrical interface to a telephone which adequately emulates that provided by standard whirling telephone networks. The key features that must be controlled are AC Termination Impedance, Transmit Gain (Telephone Microphone Output to Codec Input direction), Receive Gain (Codec Output to Telephone Speaker direction), and Hybrid Balance. AC Impedance: The SAU is designed to apply a typical telephone network AC load to an attached telephone. Ideally, the SAU will present an impedance which can be modeled as a 270 Ohm…

Filename: L:\Project\2000\p0040007\Exhibits\Alignment_Procedure.DOC Author: Daniel R. Barbour SAU-1900E ALIGNMENT PROCEDURE The SAU-1900E is a CDMA Digital Cellular Receiver/Transmitter covering the frequency range from 1850-1910 MHz (Transmit) and 1930-1990 MHz (Receive). The system design and infrastructure normally controls the SAU-1900E transmitted power level and frequency within required specifications, however initial alignment is performed to constrain the open-loop output power levels to an acceptable range. Alignment of the unit is entails loading correction factors into non-volatile memory for setting minimum and maximum transmit power levels and to ensure that open-loop power levels are maintained within the limits specified in IS-98A by entering a table of AGC control settings. This alignment is performed at initial manufacture and after repair or replacement of the RF section or following replacement of the non-volatile memory. All alignment procedures are performed under software control of the SAU-1900E and specialized CDMA Test Equipment. The equipment required to Align the SAU-1900E and a description of the procedures is provided below: EQUIPMENT: a.
