5.3 Operational status of the modem
The operational status of the modem is given by the status of the green LED
located on the front panel of the modem.
The table below gives the meaning of the various statuses available.
Table 1: Operational status of the modem

LED Flashing rapidly Modem is switched on and
registered on the network, and a

OFF LED OFF Modem is switched off.
5.4 Echo function disabled
If no echo is displayed when entering an AT command, that means:
! The “local echo” parameter of your communication software (such as
Hyperterminal) is disabled,
! The echo function of the modem is disabled.
To enable the echo function of the modem, enter the
ATE1
.
When sending AT commands to the modem by using a communication
software, it is recommended:
! To disable the “local echo” parameter of your communication software
(such as Hyperterminal),
! To enable the echo function of the modem (
ATE1
command).
In a Machine To Machine communication with the modem, it is recommended
to disable the echo function of the modem (
ATE0
command) in order to avoid
useless CPU processing.
For further information about
ATE0
and
ATE1
commands, refer to document [1].
