Sometimes when I am
trying to dial-in to the unit
or when I am connected
to the unit via the modem
and I lose my connection.
If I immediately try to dial-
in again, I can’t get
connected.
However, if I wait for a
few minutes, the dial-in is
successful. Why is this?
In this case, "a few minutes" is the key:
The modem has a pre-defined "clean up time" after every connection ends –
it does not matter whether the connection is dropped, severed, or
intentionally closed by the user.
The modem will take about one minute to re-cycle itself to be ready for the
next incoming call.
