&T8 LOCAL LOOPBACK WITH SELF TEST (See Figure 6)
The modem should be on hook. Enter AT&T8 to configure the modem for analog loopback and
self test. The test timer is started at the time indicated by S18, DSR is turned off (if &S1 is in
effect). A self test condition is entered, and an OK result code is sent to the DTE. During the test
the modem sends a test message and counts errors in the looped back signal. The test is
terminated when the timer times out (S18) or the &T0, H0, or Z command is issued. When the
test is terminated, the three digit error count is sent to the DTE. An OK result code follows the
error count.
