Incoming call management
Your modem is designed to answer incoming calls,
determine their type, and manage the open associations for
the communications programs on your computer. This
function is known as incoming call management.
When a call comes in, the modem software tries to identify
the type of call by detecting calling tones. It then checks to
see which programs are set to auto-answer and connects the
incoming call to the appropriate program.
While the modem is on, it answers calls automatically
according to the following set of rules and priorities
m The modem only answers if “Auto-answer incoming calls” is
selected in the control panel.
m The modem only answers if at least one program is set to
auto-answer.
m If several different programs are set to auto-answer, the
modem uses calling tone detection to identify the type of
call, then sends it to the corresponding program.
m Under certain conditions, if no calling tone is detected, the
call is passed to the program designated in the “Transfer
incoming calls” setting (for Express Modem), if there is an
association of that type open.
m If no association of the appropriate type is open, the call is
resolved according to an internal hierarchy.
