Modem/DSU Commands

Test type (Required field for 3900 Series modems)

Enter the call test to be performed. Valid selections are as follows:

clear counter ± Resets the call attempt counter within the device. The modem will attempt to dial backup for a maximum of 10 times. At this point, the modem must be manually commanded to dial or reset before another dial backup attempt can be executed.

dial tone ± Causes the modem to go offline and recognize a dial tone. Once a valid dial tone is recognized, the test completes by releasing the dial line. Leased-line operation is interrupted by this test.

ring detect ± Causes the modem to look for a ring tone for a maximum of 30 seconds and terminates the test when a ring tone is detected. The modem does not answer the inbound call while running the test, but aborts immediately.

Leased-line operation is not interrupted by this test.
