2. Type AT&T1 and press ENTER. This places your modem in analog loopback

mode in the originate mode. A CONNECT message should appear on your dis-

play. The modem is now out of command mode and in a pseudo-online mode.

3. Note that the CD LED is on. If you are set for 14,400 bps or higher, a speed LED

should be on. If the CD LED is not on, there is a defect in your modem.

4. Enter characters from your keyboard. For this test, typing multiple uppercase U

characters is a good way to send an alternating test pattern of binary ones and

zeros. The characters entered should be displayed on your monitor. The TD and

RD LEDs should flash when a character is entered.

5. To exit the test, type the escape sequence +++AT and press ENTER. This puts the

modem in online command mode. Then type either AT&T or ATH to return to

command mode.

6. Your modem passes this test if the data received on your monitor are the same as

the data entered from your keyboard. If different data appear on your monitor,

your modem is probably causing the problem, though it could also be your com-

puter. If your modem passes this test, but you are receiving errors while on line,

the remote modem or the phone line could be at fault.

Remote Digital Loopback Test (V.54 Loop 2)

The remote digital loopback test tests the phone lines and the circuits of both your

modem and a remote modem. In this test, your modem must be on line with another

modem that is set up to respond to a request for remote digital loopback. (Note that

some modems might not support remote digital loopback or might have it disabled.)

Data from your computer or terminal is transmitted through your modem and over

the phone line to the remote modem, where it is then looped back to your modem.
