Display AT& current settings.
ESC (pin 22) is not used.
ESC (pin 22) escapes to command mode from data mode if also enabled by HES U70, bit 15.
ESC (pin 22) assertion during a modem connection causes the modem to go on-hook and return to
command mode.
ESC (pin 22) assertion causes ATZ command (reset and return OK result code).
Line connection rate limit—This command sets an upper limit on the line speed that the Si2403 can
connect. Note that the &Hn commands may limit the line speed as well (&Gn not used for &H0 or
&H1). Not all modulations support rates given by &G. Any improper setting will be ignored.
1200 bps max
2400 bps max
Switched network handshake mode—&Hn commands must be on a separate command line from
ATD, ATA, or ATO commands.
ITU-T V.22bis only (2400 bps or 1200 bps)
ITU-T V.22 only (1200 bps)
Bell 212 only (1200 bps)
Bell 103 only (300 bps)
ITU-T V.21 only (300 bps)
V.23 (1200/75 bps)
Japan pulse dialing
Configure Si2403 for 10 pulse-per-second pulse dialing. For Japan.
Configure Si2403 for 20 pulse-per-second pulse dialing. For Japan.
Test Mode
Cancel Test Mode (Escape to command mode to issue AT&T0). This command will also report the
number of bit errors encountered on the previous &T4 test.
Initiate ITU-T V.54 (ANALOOP) test. Modulation set by &H AT command. Test loop is through the
DSP (Si2403 device) only. The Si2403 echoes data from TX pin (Register 0 in parallel mode) back
to RX pin (Register 0 in parallel mode).
Initiate ITU-T V.54 (ANALOOP) test. Modulation set by &H AT command. Test loop is through the
DSP (Si2403), DAA interface section (Si2403), isolation interface (Si3015), and analog hybrid circuit
(Si3015). Si2403 echoes data from TX pin (Register 0 in parallel mode) back to RX pin (Register 0 in
parallel mode). Phone line termination required as in Figure 1 . To test only the link operation, the
hybrid and AFE codec can be removed from the test loop by setting the DL bit (U62, bit 1).
Initiate transmit as originating modem with automatic data generation. Modulation, data rate, and
symbol rate are set by &H, &G, and S41. Data pattern is set by the S40 register. Continues until the
ATH command is sent after an escape into command mode. Data is also demodulated as in
ANALOOP, and any bit errors are counted to be displayed after the test using &T0.
