10.2.1 Checking Connection Profile Status

at^sici?
^SICI: 1,2,1,"10.10.0.161"
OK
Assume the network connection is temporarily not available. (If URC presentation mode of network
registration is enabled, the state is shown by the URC "+CREG: 2").
at^sici?
^SICI: 1,3,1,"10.10.0.161"
OK
The network connection is temporarily not available, but the Internet connection is still established, so the
host may decide to stop the data transfer to minimize the risk of losing data due to memory limitations.

^SICI: 1,2,1,"10.10.0.161"
OK
After closing the service with AT^SISC:

10.3 AT^SISS Internet Service Setup Profile

AT^SISS serves to set up the necessary parameters in the Internet service profiles. Any service
Description:
profile can then be used to control a data link in conjunction with AT^SISI, AT^SISO, AT^SISC,
AT^SISR, AT^SISW, and AT^SISE.
The read command requests the current settings of all Internet service profiles. One line is issued
for every possible parameter of a given <srvParmTag> "srvType" value.
The write command specifies the parameters for a service profile identified by <srvProfileId>. At
first the type of Internet service needs to be selected via <srvParmTag> value "srvType". This
determines the applicability of all other <srvParmTag> values related to this "srvType" and sets
their defaults. Changing the <srvParmTag> "srvType" of an existing service profile will reset all
<srvParmTag> default values to suit the new "srvType". An exception is <srvParmTag-alphabet>
which can be set before or after selecting "srvType" and is not reset when "srvType" changes.
To change the settings, the write command needs to be executed for each single <srvParmTag>.
All parameters with AT^SISS are volatile.
The list below shows which <srvParmTag> parameters apply to each Internet service and which of
them are mandatory or optional.

Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371G)
Query the current status of the connection profile.
One connection profile has been created at <con-ProfileId>=1, and one service is
opened using this connection profile. The Internet connection is in <conState>=2 ("Up").
Query once again the current status of the connection profile.
Parameter <conState> has changed to state "Limited up".
Query once again the current status of the connection profile.
After re-establishing the network connection, <con-State> reverts to state "Up".
Query once again the current status of the connection profile.
Parameter <numServices> has decreased. The bearer is still open because the
service was closed before expiry of the inactivity timeout "inactTO" of AT^SICS.
Query again the current status.
The inactivity timeout "inactTO" of AT^SICS has expired, therefore the bearer is
closed now.
