Command:
&T
n
Loopback Test (V.54 Test) Commands
Values:
n
= 0, 1, 3, 6
Default:
None
Description:
The modem can perform selected test and diagnostic functions. A test can be run only when the
modem is operating in non-error-correction mode (normal or direct mode). For tests 3 and 6, a
connection between the two modems must be established. To terminate a test in progress, the
escape sequence (+++AT) must be entered.
&T0 Stops any test in progress.
&T1 Starts a local analog loopback, V.54 Loop 3, test. If a connection exists when this
command is issued, the modem hangs up. When the test starts, a
CONNECT
message is
displayed.
&T3 Starts local digital loopback, V.54 Loop 2, test. If no connection exists,
ERROR
is returned.
&T6 Initiates a remote digital loopback, V.54 Loop 2, test without self-test. If no connection exists,
ERROR
is returned.
