Functional Description XTI UART Interface Data Bus C1 DAA Interface C2 Si3018/10 EEPROM Interface DSP EESD EECLK EECS RXD TXD CTS RTS DCD ESC RI XTO PLL Clocking Controller CLKOUT To Phone Line AOUT CS WR RD A0 D0-D7 Parallel Interface MISO MOSI SCLK SS SPI Interface The Si2493 allows for rapid integration into existing modem applications by providing a serial interface that can directly communicate to either a microcontroller via a UART interface or a PC via an RS-232 port.
Si2493 4.2. Command Mode 4.7. Low-Power Modes Upon reset, the ISOmodem® is in command mode and accepts “AT” commands. An outgoing modem call can be made using the “ATDT#” (tone dial) or “ATDP#” (pulse dial) command after the device is configured. If the handshake is successful, the modem responds with the response codes detailed in Table 12 on page 40 and enters data mode. The Si2493 provides multiple low power modes.
Si2493 4.11. V.92 PCM Upstream 4.14. Caller ID Operation The Si2493 supports the ITU-V.92 PCM upstream data protocol. This protocol allows the ISOmodem to connect at speed up to 48 kbps upstream. Previously the upstream connection rate was limited to 33.6 kbps. The PCM upstream mode is enabled by default; to disable, issue the AT command +PIG = 1 (see Table 8 on page 23). To view both downstream and upstream connect speeds in the connect result message, issue the command “AT \V4” or “AT+MR”.

Si2493 4.16. Overcurrent Detection 4.20. SMS/MMS Support The Si2493 includes an overcurrent detection feature that measures the loop current at a programmable time after the Si2493 goes off-hook. This allows the Si2493 to detect if it is connected to an improper telephone line. The overcurrent detection feature may be enabled by setting the OCDM bit (U70, bit 11). OHT (U77, bits 8:0) sets the delay after off-hook until the loop current is measured.

Si2493 5. S-Registers The S command allows reading (Sn?) or writing (Sn = x) the S-registers. The S-registers store values for functions that typically are rarely changed, such as timers or counters, and the ASCII values of control characters, such as carriage return. Table 13 summarizes the S-register set. Table 13. S-Register Description Definition S-Register (Decimal) Function Default (Decimal) Range Units 0 Automatic answer—Number of rings the Si2493 must detect before answering a call.
Si2493 Table 13. S-Register Description (Continued) Definition S-Register (Decimal) Function Default (Decimal) Range Units 24 Sleep Inactivity Time—Sets the time that the modem operates in normal power mode with no activity on the serial port, parallel port, or telephone line before entering low-power sleep mode. This feature is disabled if the timer is set to 0.
Si2493 Table 13. S-Register Description (Continued) Definition S-Register (Decimal) Function Default (Decimal) Range 42 Blacklisting—The Si2493 will not dial the same number more than two times in three minutes. An attempt to dial a third time within three minutes will result in a “BLACKLISTED” result code. If the blacklist memory is full, any dial to a new number will result in a “BLACKLIST FULL” result code. Numbers are added to the blacklist only if the modem connection fails.
Si2493 6. User-Access Registers (U-Registers) U-Registers are 16-bit registers written by the AT:Uaa command and read by the AT:R (read all U-Registers) or AT:Raa (read U-Register aa) commands (see the AT command list in Table 11 on page 37). Many aspects of the modem’s and DAA’s behavior can be enabled/ disabled, configured, monitored, and/or modified through U-Registers; however, most of them will not be needed in normal use. There are two types of U-Registers.
