“3“
6 dB power reduction with GMSK (with 4 Tx), no power reduction for 8PSK -
i.e. power profile 0 for GMSK and power profile 3 for 8PSK
“4“
(D)
Max. power reduction for GSMK and 8PSK (6dB for 4 Tx) - i.e. power profile 0
for GMSK and 8PSK
Initial Retransmission Timeout (IRT)
1...3
(D)
...60
This parameter determines the time (in seconds) the TCP/IP stack will wait
before starting the first retransmission of packets during the initial connection
establishment phase.
The TCP protocol ensures the retransmission of packets several times at
increasing intervals until some upper limit is reached.
This mechanism prevents packet loss and serious congestion problems. In
addition, the parameters
and
can be set to further optimize
this mechanism for special conditions depending on the mobile network.
Parameter is global for the ME and non-volatile. Use of default value is recom-
mended. If changed the new value takes effect the next time you
Maximum Number of Retransmissions (MR)
1...10
(D)
...30
This parameter determines the maximum number of times to retransmit TCP
packets.
The value set with
will be assumed as default for the
"tcpMR" when a new service profile is created with
. In each
service profile, you can set another "tcpMR" value which has precedence over
the global value set with
. Existing service profiles are not affected
when you change the global value via
.
Parameter is global for the ME and non-volatile. Use of default value is recom-
mended.
Overall TCP Timer for outstanding connections (tcpOT)
1...6000
(D)
This parameter specifies the number of seconds to wait before closing a con-
nection if TCP/IP packets are not acknowledged.
Setting the maximum value is practically equivalent to deactivating the tcpOT
mechanism because the maximum time would never be reached by the TCP/
IP stack.
The value set with
will be assumed as default for the
"tcpOT" when a new service profile is created with
. However,
in each service profile, you can set another "tcpOT" value which has prece-
dence over the global value set with
. Existing service profiles are not
affected when you change the global value via
Parameter is non-volatile. Use of default value is recommended.
URC mode or polling mode for Internet service commands
This parameter enables or disables the presentation of the following URCs related to Internet service com-
mands: "
" URC, "
" URC and "
" URC for parameter
=0 (Internet service events).
"
" URCs with
=1 or 2 used to indicate incoming Socket connections are always enabled.
Parameter is global for the ME and non-volatile.
“on“
(D)
Enable URCs related to Internet service commands.
Throughout the Chapter "Internet Service AT Commands" the mode is also
referred to as URC mode.
