BOCA PRO16 Reference Guide
To start an LDL test:
• Type: AT\N0 <E>
• Type: AT&T3 <E>
The operator of the remote computer should now type a few sentences
to show that the modem is operating correctly. When the remote
operator has completed the test, the test may be terminated by:
• Type: AT&T0 <E>
• Type: AT\N3 <E>
An OK message will appear.
If you have set the test timer, the test will be automatically terminated
and an OK message will appear when the timer expires.
FThe remote modem cannot terminate a local digital loopback
test. The test may only be terminated by the modem which initiated it.
Grant RDL from Remote Modem: &T4
The &T4 command configures your modem so it will grant an RDL test
if requested by a remote modem. This is the factory default setting.
Deny RDL from Remote Modem: &T5
The &T5 command configures your modem so it will prevent a remote
modem from starting an RDL test. If you request an RDL and the &T5
command has been issued to the remote modem, your modem will
return to on-line state without commencing an RDL test.
Remote Digital Loopback Test: &T6
The Remote Digital Loopback test (RDL) is similar in function to the local
analog loopback test, except that it tests your modem, the remote
modem and the telephone line. If your modem can successfully com-
plete a local analog loopback test, you can be sure that it is not at fault.
FThis test is not available when V.21, V.23, V.32, Bell 103 or Bell 212A
communication is selected. Error correction must be switched off
prior to starting the test.
