COMSPHERE 3800 Series Modems

Dial Standby/Return to Dial

The Dial Standby and Return to Dial functions appear on the LCD only after the Model 3810 or Model 3811, operating on leased lines, is placed into dial backup. Once the modem is operating in Dial Backup mode, these functions allow the modem to be switched back and forth between dial and leased-line operation while still maintaining the dial connection. See Figure 5-1. (Switching between dial and leased-line operation can be performed manually or automatically by enabling the Auto Dial Standby configuration option.)

For example, under normal dial backup conditions, when a problem occurs on the leased line, the modems establish a connection over the dial network using a telephone number stored in directory location 1.

Call Setup:

Dial Standby

F1 F2 F3

When this occurs, the Dial Standby function now appears on the LCD. By selecting this function, the modem switches back to the leased line while still maintaining the dial connection. As a result, the Return to Dial function now appears on the LCD instead of Dial Standby.

Call Setup:

Return_to_Dial

F1 F2 F3

If the leased line is found to be unacceptable, select Return_to_Dial which switches the modem back to dial network operation (LCD displays Dial Standby). If, however, the leased line is operating properly, you can select Disconnect from the Call Setup branch and drop the dial-line call.

NOTE

When the Model 3820 is configured for leased-line operation, this function is not available and is not displayed on the LCD.

To access Dial Standby or Return to Dial from the Call Setup branch, make the following selections:
