Digital Loopback Test/V.54 Loop 2 (Remote/Auto)

In this test, your modem must be On-line with another modem set up to

respond to a request for Digital Loopback (note that some modems may

not support Remote Loopback or may have this feature disabled). The

test procedure is as follows:

1. Go into Terminal mode. Type

and hit ENTER; you should get an

message.

2. Dial the remote modem by entering the Dial command and the phone

number, to establish On-line mode. Note: The

&T6

command must

be set on the remote modem to run this test.

3. Type the Escape Sequence (

+++AT<CR>

) which brings your modem

into Command mode, while still maintaining the connection with the

remote modem.

4. Type

AT&T6

and hit ENTER. The local modem responds to this

command by transmitting an unscrambled marking signal, which

causes the remote modem to place itself in Digital Loopback mode.

Then the local modem exits Command mode and enters pseudo On-

line mode.
