Table 12. Extended AT& Command Set (Command Defaults in Bold) (Continued)
Initiate ITU-T V.54 (ANALOOP) test. Modem mode set by &H AT command. Test loop is through the
DSP (Si2456/33/14 device) only. ISOmodem 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. Modem mode set by &H AT command. Test loop is through the
DSP (Si2456/33/14), DAA interface section (Si2456/33/14), ISOcap interface (Si3015), and analog
hybrid circuit (Si3015). ISOmodem 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
ISOcap link operation, the hybrid and AFE codec can be removed from the test loop by setting the
DL bit (U62, bit 1).
Compute checksum for firmware-upgradeable section of program memory. If no firmware upgrade is
installed, &T6 returns 0x0408.
