Configure Branch

Test

The Test configuration options determine specifics, such as the duration of a test, for the various diagnostic tests available to the modem.

Table 8-7 shows each Test configuration option as it appears on the LCD, with the Async Dial factory default setting (the default value if the modem is just being installed) shown following the colon (:) on the first line and with all available selections listed on the second line. Following this is a description of the configuration option, a description of the available selections, and any equivalent AT commands.

Test Configuration Options

DTE RL (CT140): Disable

Nxt Disable Enable

DTE Remote Loopback. Controls the use of Pin 21 of the RS-232D/CCITT V.24 interface by the DTE to initiate a remote loopback. An Abort command or test time-out ends this test.

Enable ± The DTE forces the modem into remote loopback when the signal on Pin 21 (CCITT 140) is turned ON. Remote Loop ends when the signal is dropped.

Disable ± The DTE does not initiate remote loopback in response to the signal on Pin 21.

The factory default is Disable.

AT command equivalent is S-register S51=n.

DTE LL (CT141): Disable

Nxt Disable Enable

DTE Local Loopback. Controls the use of Pin 18 of the RS-232D/CCITT V.24 interface by the DTE to initiate a local loopback. An Abort command or test time-out ends this test.

Enable ± The DTE forces the modem into local loopback when the signal on Pin 18 (CCITT 141) is turned ON. Local loopback ends when the signal is dropped.

Disable ± The DTE will not initiate local loopback in response to the signal on Pin 18.

The factory default is Disable.

AT command equivalent is S-register S52=n.

Test Timeout: Disable

Nxt Disable 30sec 60sec 240sec

Test Time-out. Determines how long a test runs before aborting.

Disable ± Allows a test to run indefinitely.

30, 60, or 240 seconds ± Allows the test to run for 30 seconds, 60 seconds, or 240 seconds.

The factory default is Disable.

AT command equivalent is S-register S18=n.

Rcv Remote Loop: Enable

Nxt Enable Disable

Receive Remote Loopback Response. Determines if the modem responds to a request for a remote loopback issued from a remote modem.

The factory default is Enable.

AT command equivalent is &Tn.
