1.3.5.2 Serial EEPROM Interface

A serial EEPROM is required to store the Maximum Latency, Minimum Grant, Device ID, Vendor ID, Subsystem ID, and Subsystem Vendor ID parameters for the PCI Configuration Space Header. The serial EEPROM interface connects to an Microchip 93LC66B, Atmel AT93C66, or equivalent 256 x 16 serial EEPROM. The interface signals are: a serial data input line from the EEPROM (SROMIN), a serial data output line to the EEPROM (SROMOUT), Clock to the EEPROM (SROMCLK), and chip select to the EEPROM (SROMCS). The EEPROM is programmable by the PC via the BIF.

1.3.5.3 Audio Interface

One Speaker output (SPKROUT_M) is provided for an optional OEM-supplied speaker circuit. Two microphone inputs are supported: one for Voice Microphone input (MIC_V) and one for Music Microphone input (MIC_M), e.g., music-on-hold.

The MIC_V and SPKROUT_M lines connect to the handset and speaker to support functions such as AudioSpan headset and speakerphone modes, FDSP, telephone emulation, microphone voice record, speaker voice playback, and call progress monitor.

The MIC_M input can accept an external audio signal to support the music-on-hold function and routes it to the telephone line. If music-on-hold function is not required, the microphone signal can be connected to the MIC_M input to support telephone emulation mode.

The Speaker output (SPKROUT_M) carries the normal speakerphone audio or reflects the received analog signals in the modem.

1.3.5.4 Telephone Line/Telephone/Audio Interface

The Telephone Line/Telephone/Audio Signal Interface can support a 3-relay telephone line interface (Figure 1-3). Signal routing for Voice mode is shown in Table 1-2. Relay positions for VoiceView are shown in Table 1-3.

The following signals are supported:

A single-ended Receive Analog input (RXA_L1) and a differential Transmit Analog output (TXA1_L1 and TXA2_L1) to the telephone line.

Off-hook (OH_L1#), Caller ID (CID_L1#), and Voice (VOICE_L1#) relay control outputs.

A Ring Indicate (IRING_L1) input.

A Loop Current Sense (LCS) input.

An input from the telephone microphone (TELIN_L1) and an output to the telephone speaker (TELOUT_L1 ) are supported in AudioSpan modes. These lines connect voice record/playback and AudioSpan audio to the local handset.
