2.11 ATE Enable command echo
Write command
ATE[<value>]
This setting determines whether or not the TA echoes characters received from
TE during command state.
TE during command state.
Response
OK
Parameter
<value> 0 Echo mode off
1 Echo mode on
Reference
V.25ter
Note
In case of using the command without parameter, <value> is set to 0.
2.12 ATH Disconnect existing connection
Execute command
ATH[n]
Disconnects any call in progress, such as voice calls, CSD data calls and active
GPRS connections. Cancels an active PDP context.

Response
OK
Note:
OK is issued after circuit 109 (DCD) is turned off (RS-232 level), if it was previ-
ously on.

Note
Using ATH in Multiplex mode (AT+CMUX)
• ATH terminates every data call, even if it is issued via logical channels 2 or 3.
• ATH terminates every data call, even if it is issued via logical channels 2 or 3.
• This behaviour is in accordance with ITU-T V.25 ter; (07/97, see “6.3.6 Hook
control“: "ATH is terminating any call in progress")
Using ATH while GPRS is active (PDP context is activated or online):
• CAUTION: The execution of ATH cancels an active PDP context. This takes
• CAUTION: The execution of ATH cancels an active PDP context. This takes
effect no matter whether ATH was used to end a voice or data (CSD) call, to
manually reject a network requested PDP context activation as described in
Chapter 6.3.2 or to terminate a call on one of the virtual channels in Multiplex
mode.
The context deactivation can be avoided by terminating a current call with
AT+CHLD=1 instead of ATH. See Chapter 4.16 for AT+CHLD.
