Test procedure

1.Arrange to have &T6 set on the remote test modem.

2.Open your communications software and go into terminal mode. Type AT and press ENTER; you should get an OK message. Type AT\N and press ENTER to disable error correction.

3.Dial the remote modem and establish your online connection.

4.Type the escape sequence +++AT and press ENTER to bring your modem into online command mode.

5.Type AT&T6 and press 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 online command mode and enters data mode.

6.Enter data from your keyboard. For this test, typing multiple upper- case U characters is a good way to send an alternating test pattern of binary ones and zeroes. Data received by the remote modem enters its analog receiver, is converted to digital data, is reconverted into analog, and then is transmitted back to your modem. Your mo- dem passes this test if the data received on your monitor is the same as the data entered from your keyboard.

7.To exit the test, type the escape sequence +++AT and press EN- TER. This puts the modem in online command mode. The modem should respond with an OK message. If you wish to stay on line with the remote modem for normal data transmission, type AT&T and press ENTER to exit the test, then type ATO and press ENTER to return on line. If you wish to terminate the call, type ATH and press ENTER to hang up.
