Digital line guard
The modem has an optional Digital Line Guard Circuit that automatically detects an over current
situation on the Tip and Ring pins. When the modem goes off hook, it will immediately check the
current on the Tip and Ring pins. If the current exceeds 150 mA, the modem will display the
“DIGITAL LINE DETECTED” result code and then go back on hook. The modem will continue to
display this result code until normal current is detected on the Tip and Ring pins during an off hook
condition. The DLG feature will protect the modem in case it is accidentally connected to a Digital
Telephone Line.
Sleep mode operation
The modem can be set to enter the low power sleep mode by setting ATS24=n. In this case, “n” is
time, in seconds, that the modem will operate in normal mode with no detected telephone line or
DTE line activity before entering low power sleep mode. The timer is reset upon any DTE or
telephone line activity. If S24 is set to zero, the modem will never enter the low power sleep mode.
Disconnecting a call
There are several ways to disconnect a call. Below are the choices.
• Resetting the modem’s power or toggling the Reset Line (Pin #12) will disconnect and put the
modem back into the OFF line state.
• An ON to OFF transition of the DTR signal (Pin #4) will also disconnect the modem. If you
use this method, check to make sure that the DTR command is set to &D2 or &D3 and not
forced (&D0).
